Puppy Care Guide
Canis lupus familiaris
The first 16 weeks set the pattern for the rest of your dog's life — socialization, vaccinations, and training foundations all happen on overlapping timelines during this window.
Lifespan
10-15 years on average, varies significantly by breed and size
Adult size
Varies enormously by breed — confirm expected adult size before adopting
Diet
Puppy-formulated food, 3-4 meals/day tapering to 2/day by 6 months
Temperament
Varies by breed and individual; socialization in the first 3 months shapes adult behaviour
Housing
Crate sized to the adult dog (or a divided crate), plus a puppy-proofed area
Legal notes
Municipal licensing is required in most Canadian cities; some municipalities have breed-specific legislation — check local bylaws before adopting
Puppyhood is a short, high-stakes window — the first three months overlap the core vaccination series, the peak socialization period, and the start of house training, all at once. Getting the basics right early makes life dramatically easier once your dog is an adult.
Housing & crate training
- Choose a crate sized so the puppy can stand, turn around, and lie down comfortably — not much bigger, or it defeats the den effect used for house training
- For growing breeds, buy an adult-sized crate with a divider panel rather than replacing crates as the puppy grows
- Introduce the crate gradually with treats and short positive sessions before expecting the puppy to sleep in it overnight
- Never use the crate as punishment — it should be a safe, calm space the puppy chooses to enter
- Expect several nighttime bathroom wake-ups in the first weeks; very young puppies can't hold their bladder through a full night
Feeding schedule & food transitions
- Feed a food specifically labelled for puppies (or 'all life stages') — adult dog food doesn't have the calorie and nutrient density growing puppies need
- Typical schedule: 4 meals/day at 8-12 weeks, 3 meals/day at 3-6 months, transitioning to 2 meals/day by around 6 months
- When switching foods, mix old and new gradually over 7-10 days to avoid digestive upset
- Follow the feeding guide on the food bag as a starting point and adjust based on body condition, not just weight
- Avoid free-feeding (leaving food out all day) during house training — scheduled meals make bathroom timing predictable
Core vaccination schedule
- Puppies typically start their vaccine series around 6-8 weeks of age with a combination vaccine covering distemper, parvovirus, and other core diseases
- Booster shots are usually given every 3-4 weeks until the puppy is about 16 weeks old, since maternal antibodies can interfere with earlier doses
- A rabies vaccine is typically given once the puppy reaches the minimum age required by your vet and province, often around 12-16 weeks, and is legally required in most of Canada
- Exact timing and which vaccines are 'core' vs. 'lifestyle-dependent' varies by vet, region, and the puppy's risk factors — confirm the specific schedule with your veterinarian rather than following a generic timeline
- Keep the vaccination record — many boarding facilities, groomers, and puppy classes require proof before your puppy can attend
Basic training foundations
- Start potty training immediately: take the puppy out first thing in the morning, after meals, after naps, and after play — consistency matters more than frequency
- Reward the puppy immediately after it eliminates outside, not after coming back inside, so it connects the reward to the right action
- Begin name recognition and recall in a low-distraction environment (like your living room) before expecting it to work outdoors
- Use short, positive training sessions (5-10 minutes) multiple times a day rather than long sessions — puppy attention spans are short
- Puppy-proof the home before the puppy arrives: secure cords, remove small chewable objects, block access to stairs if needed, and store household chemicals out of reach

Frequently asked questions
Most puppies start the core vaccine series around 6-8 weeks old, with boosters roughly every 3-4 weeks until about 16 weeks, plus rabies around 12-16 weeks depending on provincial requirements. The exact schedule varies by vet and region, so confirm the specific plan with your veterinarian at the first appointment.

Corn snakes are one of the most beginner-friendly pet snakes, but they're also notorious escape artists — enclosure security matters as much as heat and feeding.
- Finches (e.g. Zebra Finch)
Finches need horizontal flying space more than they need a tall cage — a lot of standard bird cages are actually the wrong shape for a finch's needs.

Pet snails are genuinely low-maintenance, but a few basics — humidity, calcium, and ventilation — make the difference between a healthy shell and a cracked or eroded one.

Guppies are a classic beginner fish for good reason, but their easy livebearing reputation cuts both ways — without a plan, a small guppy tank turns into an overcrowded one fast.
