Bringing Home a Shih Tzu: First Week Calgary

Q: What do I need to buy before bringing home a Shih Tzu?

Twelve core items cover most Calgary households. A step-in harness with a back attachment (never a flat collar for walks, since pressure on a Shih Tzu trachea can aggravate a brachycephalic airway). A wire crate 24 to 30 inches with a divider. A washable crate bed and two blankets. Stainless or ceramic food and water bowls (plastic causes chin acne in some dogs). A slow-feeder or puzzle bowl. The same food the rescue or breeder has been feeding, for a 7 to 10 day gradual transition. Eye and face-fold wipes plus an ear cleaner. A 4-foot nylon or biothane leash. A cooling mat for summer. A frozen Kong and small training treats. Pet insurance enrolled before the first vet visit. A Calgary vet appointment booked within 7 days of pickup.

Q: What is the 3-3-3 rule for new dogs?

The 3-3-3 rule is a rough timeline used by rescues to describe how a newly adopted dog settles. Roughly the first 3 days are decompression: a Shih Tzu may hide, sleep heavily, refuse food, follow you from room to room, or sit unusually quiet. Roughly the first 3 weeks are routine forming: the dog learns the household schedule, where the potty area is, and which humans are safe. Roughly the first 3 months are when true personality emerges: a calm Shih Tzu may turn out to be a busy lap-shadow, or a shy dog may start asking for play. The rule is directional, not a deadline. Many rescue Shih Tzus from puppy-mill backgrounds take longer.

Q: My new Shih Tzu will not eat. Should I worry?

Skipping one to two meals in the first 24 to 48 hours is common for newly adopted Shih Tzus, especially adults from rescue. Stress, a new environment, and a food change can all dampen appetite. Offer the same food the rescue or breeder used, at the same times, in a quiet spot away from foot traffic. If a Shih Tzu has refused food for more than 24 hours and you also see vomiting, diarrhea, lethargy, or visible breathing effort, call your vet that day. Puppies under 6 months should not skip meals: they are at risk of hypoglycemia. If a puppy refuses one meal, contact your vet or the rescue right away.

Q: How long does it take a Shih Tzu to adjust to a new home?

Most Shih Tzus show meaningful settling by weeks 3 to 4. Full personality usually emerges by month 2 to 3. Velcro behaviour (following you everywhere) tends to start within days. Sleeping through the night typically settles in the first 1 to 2 weeks. Housetraining for adults usually solidifies between weeks 4 and 8. Shih Tzus from puppy-mill or breeding-kennel backgrounds often take 6 to 12 months to fully decompress. Slow progress is normal and not a sign you chose the wrong dog.

Q: When should the first vet visit happen?

Book the first vet appointment within 7 days of pickup. The wellness exam establishes a baseline weight, body condition score, dental check, and a brachycephalic airway assessment. The vet will confirm vaccinations, parasite status, microchip, and review medical paperwork from the rescue or breeder. Calgary first-visit wellness exams typically run $80 to $150 and may be longer for a senior. Enroll pet insurance before the wellness exam, because anything noted at the appointment can later be treated as pre-existing by some insurers. If you bring home a Shih Tzu with active eye discharge, breathing difficulty, or visible discomfort, do not wait the full 7 days, call sooner.

Q: What are the most common first-week mistakes?

Six mistakes show up across new Calgary Shih Tzu owners. Inviting too many friends, family, and other dogs over in week 1, which overwhelms a small dog still decompressing. Using a flat collar for walks instead of a harness. Changing the rescue or breeder food cold-turkey instead of over 7 to 10 days. Forcing handling and grooming on day 1 to 2 when the dog is still frozen. Leaving a Shih Tzu alone for a full workday in week 1 instead of building alone-time gradually. Skipping or delaying the wellness exam past day 7. Most are easy to undo, but the first week sets habits.

Q: How do I introduce my Shih Tzu to existing pets?

Wait until your Shih Tzu has settled, usually 2 to 4 weeks, before active introductions. For existing dogs: first meet on neutral ground (a sidewalk, not the living room), then walk parallel, then move to the home with both on lead. Keep early shared time short and positive. For cats: use a baby gate or x-pen so both animals can see and smell without contact, swap scent through bedding, and only allow direct contact once both are calm. Shih Tzus generally have low prey drive and do well with cats, but supervise the first weeks. For children: supervise every interaction in week 1 to 4 regardless of household experience, and teach kids to let the dog approach them.

The short answer

For the first 3 days, keep your new Shih Tzu's world small: one quiet room, a crate or x-pen, the same food the rescue or breeder used, and almost no visitors. For the first 3 weeks, lock in a routine: same potty spots, same meal times, short positive training sessions, and a slow build to alone time. Book the first vet visit within 7 days of pickup, enroll pet insurance before that appointment, walk on a harness (never a flat collar), and plan around Calgary's climate from day 1. That means cooling indoors in summer, a coat and short walks below -10°C in winter. The 3-3-3 rule is the frame: 3 days, 3 weeks, 3 months. Most Shih Tzus settle on that arc; mill-background dogs take longer, and that is normal.

A small Shih Tzu being welcomed into a Calgary home with a crate, harness, and starter supplies visible — A new Shih Tzu's first week is mostly about quiet, routine, and small wins. The setup matters more than any training session.

Before pickup: the small-breed supply checklist

Most of what a Shih Tzu needs is small-breed appropriate: bowls a flat face can drink from comfortably, a harness designed for narrow chests, a coat that actually fits a 9 to 16 lb dog. Buy the core kit before pickup so the first 48 hours are about settling, not shopping. Calgary cost ranges below are typical at Pet Valu, Bosley's, Tail Blazers, and large-format pet stores; online options vary.

Item	Calgary cost	Why it matters for a Shih Tzu
Step-in harness (XS / S)	$25 to $55	Spreads leash pressure off the trachea; safer for a brachycephalic breed than a flat collar.
Wire crate (24 to 30 inch) + divider	$60 to $110	Safe space, housetraining tool, future vet-recovery setup.
Washable crate bed + 2 blankets	$35 to $80	Soft surface protects the spine; washable for accidents week 1.
Stainless or ceramic bowls (shallow)	$20 to $40	Flat faces drink and eat more easily from shallow bowls; no plastic.
Slow-feeder / puzzle bowl	$15 to $30	Reduces gulping, helps with airway-friendly eating.
Eye/face wipes + ear cleaner	$25 to $45	Daily wiping prevents tear staining and face-fold infections.
4-foot leash (nylon or biothane)	$20 to $40	Short leash gives a small dog clear guidance on city sidewalks.
Winter coat + booties (4-pack)	$50 to $110	Small short-snouted breeds lose heat fast in Calgary cold snaps.
Cooling mat (summer)	$25 to $55	Brachycephalic dogs overheat fast; passive cooling helps.
Frozen Kong + training treats	$25 to $50	Alone-time conditioning + decompression chewing.
Pet insurance (enrolled day 1)	$50 to $120/mo	Pre-existing exclusions take effect after the first vet visit.
Day-1 setup total	$350 to $720	Plus first-month insurance and wellness exam.

Calgary cost ranges are directional; actual prices vary by retailer and season. Costs cited for example only.

Pickup day: what to expect on the drive home

Calgary pickups happen across the city: from Calgary Humane Society in the south, from AARCS intakes, from Pawsitive Match Rescue Foundation fosters, and from breeders out in Airdrie, Okotoks, or Cochrane. For a small Shih Tzu the car ride home matters more than the breed pages suggest. Three details to plan for:

Secure restraint. A crash-tested small-dog crate strapped to the back seat is safest. A loose dog in the front seat is dangerous for both of you and not legal under Calgary distracted-driving rules.
Temperature. In summer, pre-cool the car and never leave a Shih Tzu unattended. In winter, warm the car first; a cold cabin is rough on a short-coated small dog.
Carsickness is common. Many Shih Tzus drool, pant, or vomit the first car ride. Skip the meal right before pickup, bring a towel, and keep the ride direct (no errands).

Expect a quiet dog on arrival. Some Shih Tzus shut down completely for the first 24 to 48 hours; others act fine and then crash on day 3. Both patterns are normal.

The 3-3-3 rule, applied to a Shih Tzu

The 3-3-3 rule is the timeline rescues use to describe decompression: 3 days, 3 weeks, 3 months. For Shih Tzus the pattern looks like this:

Days 1 to 3 · decompression

Hidden, scared, may not eat

Many newly adopted Shih Tzus go quiet in the first 72 hours. Expect skipped meals, sleeping in the back of the crate, refusing to make eye contact, or velcro-following one person. Some shake. None of this means they dislike you. Your job is low pressure: same room, same food, same potty spot, no visitors, no grooming session. Talk softly, drop treats nearby, and let the dog set the pace for contact. Adult puppy-mill survivors may stay in this phase 1 to 2 weeks.

Weeks 1 to 3 · routine forming

Trust building, potty training, alone-time conditioning

Personality starts emerging around day 4 to 7. Housetraining for adult rescues usually solidifies in weeks 2 to 4. Separation anxiety tends to peak around week 2, especially after you return to work, so build alone time slowly (start with 5 to 10 minute departures, then 30 minutes, then a couple of hours). Keep the schedule boring: same wake-up, same meals, same walks. Boring is what builds trust.

Months 1 to 3 · full personality

The real Shih Tzu emerges

By month 2 to 3, the dog you signed up for usually shows up. A shy Shih Tzu may turn out playful, a calm one may reveal a stubborn streak, a mill survivor may finally wag at the door. Some new behaviours surface as comfort grows (resource guarding around food, barrier reactivity at the window). Treat the first 3 months as a non-decision window: do not rehome unless safety is at stake.

Setting up the home: spaces, gates, and the safe spot

A Shih Tzu does not need a big setup, but it does need a deliberate one. Five zones worth defining before pickup:

The safe spot. A crate or x-pen in a low-traffic corner with bed, water, and a Kong. Place it in or near your bedroom for the first week so a velcro dog is not isolated overnight.
Gated areas. Baby gates at the top and bottom of stairs (Shih Tzu spines are vulnerable to disc injury from stair tumbles). Block off any room you do not want the dog in until housetraining is solid.
Potty area. One outdoor spot near the door for fast trips in cold weather, plus an indoor backup (pee pads in a tray or a small artificial-turf patch) for Calgary's coldest weeks. Many Shih Tzus refuse to potty in deep snow or below -15°C without an indoor option.
Feeding station. Quiet corner, shallow bowls, slow-feeder, away from foot traffic. A dog that startles while eating learns to guard food.
Grooming station. A non-slip towel on a counter or table where face-wipes, eye care, and brushing happen daily. Familiarizing a Shih Tzu with this spot in week 1 saves grooming battles later.

Daily routine in week 1

Predictable schedules speed up settling more than any single training trick. A reasonable Shih Tzu day for the first week:

Time	Activity
7:00 am	Wake, immediate potty trip, short sniff walk if calm.
7:30 am	Breakfast in quiet feeding spot. Slow-feeder bowl.
8:00 am	Face wipe, eye check, light brush. Two minutes max.
10:00 am	Potty trip, frozen Kong in the safe spot, 30 to 60 min alone-time practice.
12:00 pm	Lunch (puppies) or potty + sniff break (adults). Short on hot or cold days.
3:00 pm	Potty trip, 5 min positive reinforcement session (name recognition, sit).
5:30 pm	Dinner. Quiet meal, same spot.
7:00 pm	Calm walk on harness, 15 to 25 min depending on weather.
9:30 pm	Last potty trip. Lights down, settle in crate.
2:00 am (puppies only)	One overnight potty trip in the first few weeks for puppies under 6 months.

A Shih Tzu settled on a crate bed in a Calgary home during the first week of decompression — By weeks 2 to 3, most Shih Tzus settle into a routine. The crate becomes a chosen safe spot rather than a confinement.

Feeding: gradual transition over 7 to 10 days

Whatever food the rescue or breeder has been using, get a 1 to 2 week supply at pickup. A cold-turkey food switch causes diarrhea, vomiting, and skipped meals on top of an already stressful arrival. Transition gradually over 7 to 10 days (per AAHA standard guidance):

Days 1 to 3: 75% old food, 25% new food.
Days 4 to 6: 50% old, 50% new.
Days 7 to 9: 25% old, 75% new.
Day 10+: 100% new food.

Feed 2 to 3 small meals daily for adults, 3 to 4 for puppies under 6 months. Use a slow-feeder bowl: Shih Tzus gulp food, which makes a brachycephalic airway work harder. Keep the meal spot quiet, do not stand over a dog while it eats, and let the dog finish at its own pace.

If your Shih Tzu refuses food entirely for over 24 hours and you also see vomiting, diarrhea, lethargy, or breathing difficulty, call your vet. For puppies under 6 months, any skipped meal is worth a phone call: small-breed puppies can drop into hypoglycemia quickly.

Calgary climate notes: heat-sensitive in summer, cold-sensitive in winter

Shih Tzus are brachycephalic (short snout) and small. That combination means they handle weather extremes worse than most breeds. The American Veterinary Medical Association notes brachycephalic dogs have reduced airway capacity and overheat faster than non-brachycephalic breeds (AVMA brachycephalic statement). Calgary's climate hits both ends:

Summer (May to September):

Above 22°C, shift walks to before 8 a.m. and after 8 p.m. Hot pavement burns small paws faster than a Lab's.
Above 27°C, skip walks and use indoor play or the cooling mat instead.
Never leave a Shih Tzu in a parked car. Even 10 minutes in a Calgary July car can be fatal.
Check breathing during play. Heavy panting, gum colour changes, or stumbling means stop and cool down.

Winter (November to March):

Below -10°C, limit outdoor time to 5 to 10 minutes. Use a fleece or insulated coat.
Below -20°C, potty trips only. Booties protect paws from salt and ice. Indoor pee pads are a reasonable backup during cold snaps.
Watch for shivering and lifted paws, which mean the dog is too cold.
Chinooks (sudden warm-ups) can swing daytime temperatures 20°C in hours. Recheck conditions before each walk.

Sleeping arrangements: crate, bed, or yours

Most Calgary trainers recommend the crate or x-pen near your bed for the first 1 to 2 weeks. A velcro Shih Tzu separated to another room usually cries through night 1 and reinforces panic. After settling, the choice is yours. A few realities:

Crate in bedroom. Best default. Quiet, contained, near you. Most adult rescues sleep through within a few nights.
Dog bed on the floor. Works once housetraining is solid (typically week 4+ for adults). Use a non-slip mat under it.
Your bed. Many Shih Tzus end up here, and there is no health reason to avoid it for an adult dog. Two caveats: do not lift onto a high bed without ramp or steps (IVDD risk), and resource guarding around sleeping spots can develop with some dogs.
Puppies. Stay crated near you for at least the first 2 to 3 months. Bed-sharing under 6 months can suppress housetraining progress.

The first vet visit: book within 7 days

Book the wellness exam before pickup if you can. The first appointment is short (30 to 45 min) and establishes:

Baseline weight, body condition score, dental check, brachycephalic airway assessment.
Vaccination status review and any missing boosters.
Microchip and parasite-prevention plan.
Eye condition baseline (Shih Tzus are prone to dry eye, proptosis, and corneal ulcers per the American Shih Tzu Club health page).
Dental baseline (small breeds, especially Shih Tzus, develop dental disease early; the AKC Shih Tzu breed page highlights dental care as a lifelong priority).

Calgary wellness exam pricing typically runs $80 to $150 for a first visit (directional; costs vary by clinic). Bring all paperwork from the rescue or breeder. Ask about a baseline blood panel for seniors. Take notes on the vet's recommended deworming, flea/tick, and heartworm schedule.

Enroll pet insurance before the wellness exam. Anything noted at that appointment can become a pre-existing exclusion for some insurers later. The ASPCA new-pet guide also recommends scheduling a wellness exam within the first week as a general rule for all newly adopted dogs.

The most common first-week mistakes

These are the patterns that show up most often in Calgary rescue follow-up calls and rehome-risk surveys. None is fatal, but each makes the first month harder than it needs to be.

Too many visitors in week 1. A small dog still decompressing cannot meet your whole social circle. Hold guests off for 7 to 14 days.
Flat collar on the walk. Use a step-in harness. A collar pulling on a Shih Tzu trachea is the wrong gear for a brachycephalic breed.
Cold-turkey food switch. Causes diarrhea and skipped meals during a phase when you need stable digestion. Transition over 7 to 10 days.
Forcing the bath on day 1. Wait until at least week 2 for the first full grooming session. Wipes and a short brush are plenty for week 1.
Skipping the wellness exam past day 7. Delays the insurance baseline and misses early dental, eye, or airway issues.
Treating shutdown as “the dog is fine.” A Shih Tzu sleeping all day on day 2 is decompressing, not adjusted. Real personality usually shows after day 4.
Returning to a full workday in week 1. Build alone time slowly. Separation anxiety often peaks around week 2, especially if alone-time training was skipped.
Walking outside in extreme weather without gear. Below -10°C or above 22°C, a small brachycephalic dog without climate gear is at real risk.

Frequently asked questions

What do I need to buy before bringing home a Shih Tzu?

A step-in harness (never a flat collar), wire crate 24 to 30 inches, washable bed and blankets, shallow stainless or ceramic bowls, a slow-feeder bowl, the same food the rescue or breeder used, eye and face wipes, ear cleaner, a short leash, a winter coat and booties, a summer cooling mat, a frozen Kong, and pet insurance enrolled before the first vet visit. Setup total in Calgary is typically $350 to $720.

What is the 3-3-3 rule for new dogs?

A directional timeline: roughly 3 days of decompression (quiet, may not eat, may hide), roughly 3 weeks of routine forming (housetraining, alone-time conditioning), and roughly 3 months for full personality to emerge. Mill-background and senior Shih Tzus often take longer.

My new Shih Tzu will not eat — should I worry?

Adults skipping 1 to 2 meals in the first 24 to 48 hours is common from stress. Stay with the rescue's food, in a quiet spot. Call your vet if it goes beyond 24 hours or you see vomiting, diarrhea, lethargy, or breathing difficulty. Puppies under 6 months should not skip meals: call the rescue or your vet right away if a puppy refuses food.

How long does it take a Shih Tzu to adjust to a new home?

Meaningful settling by weeks 3 to 4 for most. Full personality by month 2 to 3. Sleeping through the night by week 1 to 2. Housetraining for adults usually solidifies by week 4 to 8. Mill survivors take 6 to 12 months.

Should I crate train my new Shih Tzu?

Most Calgary trainers and rescues recommend introducing a crate from day 1, even if you do not use it long-term. Place it in or near your bedroom for the first week. Use positive associations (Kong, treats) and never use the crate as punishment.

When should the first vet visit happen?

Within 7 days of pickup. The exam sets a baseline for weight, dental, eye, and airway, and lets you enroll pet insurance before any pre-existing exclusions kick in. Calgary first-visit pricing typically runs $80 to $150.

What are the most common first-week mistakes?

Too many visitors, flat collar instead of harness, cold-turkey food switches, forced bathing on day 1, skipping the wellness exam past day 7, mistaking shutdown for adjustment, and going back to a full workday in week 1 without building alone time first.

How do I introduce my Shih Tzu to existing pets?

Wait 2 to 4 weeks until the dog is settled. For other dogs: meet on neutral ground, walk parallel, then move home with both on lead. For cats: gate-and-scent-swap first, then short supervised sessions. For kids: supervise every interaction for the first month and teach kids to let the dog approach them.
