Why puppy-proof your home
To a puppy, everything is new. It has no idea that an electrical cord, a plant, or a cleaning product could hurt it, or that the furniture and your shoes are not toys. It is up to you to adapt the home: removing hazards prevents veterinary emergencies, and it spares your belongings too. Everything is easier afterward, for both of you.
Handy equipment
- A crate and a comfortable bed
- Food and water dishes
- Toys, including dog chew toys
- Safety gates (baby gates)
- Child-proofing supplies: latches, outlet covers
- A collar with an ID tag and a microchip: a puppy that slips out the door gets home faster
- Our number and a 24/7 emergency clinic's, saved before you need them
Never punish a puppy
This is the single most important point in this guide. When a puppy makes a mess, chews something, or has an accident indoors, the natural reaction is to scold. Resist that urge.
Why punishment backfires
A puppy does not connect a loud voice or a smack with an act that felt perfectly natural, even when caught in the act: it mainly learns to hide from you (for example to eliminate out of your sight), which is sometimes mistaken for 'he knows he did wrong.' In truth it grows confused and anxious, and new behavior problems can appear.
Do this instead: reward
Show your puppy what is allowed and praise every good behavior, with petting, kind words, or a treat. For this to work, meet its needs for its age and energy: a well-occupied puppy gets into far less trouble.
Mouthing is normal (and not to be punished)
Mouthing and nipping are part of a puppy's normal development, especially while teething: it is not aggression. When its teeth touch your skin, redirect it right away to a chew toy, or pause the game and withdraw your attention for a few moments. Never wrestle with your hands.
Remove the hazards
Go through each room at puppy height. Anything that can hurt it should be out of reach or behind a door. Some rooms, like the garage, the shed, or a storage basement, are best kept off-limits entirely.
Deadly hazard: antifreeze
Antifreeze (ethylene glycol) is sweet and it kills dogs. It is often bright green, but also orange, pink, yellow, or blue depending on the product: do not rely on color. Even a small amount, a puddle a puppy laps up, can cause fatal kidney failure within 48 to 72 hours. The poison acts before any symptom shows, and the antidote only works in the very first hours: at any contact, go to the clinic without waiting. Store it out of reach, wipe up any spill, and take leftovers to a hazardous-waste depot.
Poisons and dangerous products
- Electrical cords, extension cords, and power strips
- Rodenticides (mouse and rat bait), often at floor level
- Cannabis, THC, and edibles (often mixed with chocolate or xylitol)
- Cleaning products and other chemicals
- Human and veterinary medications, especially anti-inflammatories (ibuprofen, naproxen), acetaminophen, ADHD stimulants, and antidepressants (check under furniture)
- Trash, compost, and moldy leftovers (molds: tremors, seizures)
- Toxic house plants (sago palm, dieffenbachia, azalea…)
Foods dangerous to dogs
- Chocolate and coffee (caffeine)
- Xylitol (also labelled birch sugar): sugar-free gum and candy, some peanut butters
- Grapes and raisins
- Onion, garlic, chives
- Macadamia nuts, alcohol
- Cooked bones (splinter: risk of blockage or perforation)
Small objects they can swallow
- Coins and button batteries
- Socks, string, hair elastics
- Small toys and detachable parts
- Risk of choking, blockage, internal burns (button batteries), or zinc poisoning (galvanized hardware)
Targets for destruction
- Shoes, clothing, children's toys
- Books, magazines, remote controls
- Toilet paper, trash cans, rags
- Candles, and food left on the counter
Simple strategies that work
Close doors, set up gates, store things in cabinets or closets, and keep your puppy in view whenever it is not in a secured space. Supervision is your best tool.
Meet their needs
Puppy-proofing is not only about taking away: it is also about providing. A puppy needs to chew, tug, play, and learn. Give it the right objects and the right outlets, and it will turn to your belongings far less.
Things to chew
Offer sturdy but not rock-hard chew toys and food-dispensing toys, big enough that it cannot swallow them (aim for about four times the size of its mouth). Avoid very hard objects (antlers, hooves, bones, rigid nylon) that can fracture a tooth: if you cannot dent it with a fingernail or it would hurt to tap your kneecap, it is too hard. Save rawhide for supervised time only, since a puppy can swallow large, slow-to-digest pieces that may cause a blockage. Supervise at first, wash them regularly, and toss any damaged toy. A food-stuffed toy (such as a Kong) keeps a puppy busy during quiet time.
A puppy class
Puppy classes build social skills with people and other dogs, and your bond. Choose a certified trainer who uses only positive methods, without fear, force, or pain.
Safe play
Always play with a toy, much bigger than its mouth (about four times) or its head (twice), so it never mistakes your hand for a target. Never lift it off the ground by the toy. Teach it to take, to drop, and to trade for a rewarded 'sit': trading an item for something better prevents resource guarding, so never snatch food or an object away from it. Off-leash only in a known, fenced area.
A puppy's first weeks count double
A puppy's first weeks are a sensitive period for socialization (roughly 3 to 14 weeks). Calm, positive, gradual experiences during this window (meeting a variety of people, friendly well-vaccinated dogs, everyday sounds, different surfaces, and gentle handling) shape a confident adult. It is also the reason to start a positive-methods puppy class early. Because this window closes before the first vaccine series is finished, ask us how to socialize your puppy safely in the meantime.
Set up the space
A young puppy is easier to watch in a single room than in the whole house. Limit its territory to wherever you are, and secure heights and edges.
- One room at a time: for a very young puppy, keep it where you can see it.
- Gates on the stairs: top and bottom, to prevent falls.
- Balconies, decks, and upper-floor windows: block access to anywhere it could fall from; a screen won't hold a puppy.
- Railings and balusters: check that it cannot get its head stuck.
- Blind and curtain cords: tie them up out of reach or switch to a cordless style (strangulation risk).
- Water hazards: pools, buckets, bathtubs, and toilets (keep the lid down) are a drowning risk.
- An exercise pen: a safe space for when you cannot supervise.
- Garage, shed, basement: best kept off-limits entirely.
Falls and stuck heads
Puppies fall and get their heads stuck more often than you would think. A well-placed gate and a quick look at railing gaps prevent a lot of accidents.
Leaving them alone takes thought
Dogs are social animals. Absences need planning, especially while the puppy is not yet housetrained.
- Get it used to alone time early: short absences first, lengthened little by little, with calm departures and returns; a puppy that gradually learns to be alone develops less separation anxiety.
- Until it is housetrained: keep absences short and regular.
- A small puppy: needs to go out about every hour to urinate.
- A young small-breed dog: needs to go out every few hours, even once housetrained.
- 4 hours alone or more a day: a dog can then experience stress.
- Never alone in a car: a cabin turns deadly hot within minutes; in the car, buckle it in or crate it.
- For longer absences: consider doggy daycare or a pet sitter.
The crate, done gently
If you use a crate for housetraining or safety, introduce it patiently, as a pleasant den, never as punishment. Done well, many dogs come to love it as a safe retreat.

When to rush to the vet
Some situations cannot wait. At the slightest doubt, call us or go to an emergency clinic: with poisons, every minute counts. Acting fast is already the right move: call and we will guide you.
Suspected poisoning
Antifreeze, chocolate, xylitol, grapes, cannabis, medication, a plant, rodent bait… If you think your puppy swallowed something toxic, or if it suddenly trembles or has seizures after getting into the trash, do not wait for symptoms and do not make it vomit without advice: get to the vet and bring the packaging. Tell us honestly what it swallowed, cannabis included: it does not change how you are received and lets us treat faster. For antifreeze especially, treatment must begin within hours.
A swallowed object or battery
Choking, gagging, repeated vomiting, refusing food, or a painful belly after swallowing something: this is urgent. A swallowed button battery, magnet, or piece of string is especially dangerous: a battery can burn the esophagus within hours, magnets can pinch loops of bowel together, and string can saw through the intestine. Do not wait for signs to appear, even if the puppy seems fine.
A chewed electrical cord
If it is still in contact with the cord, first cut the power at the breaker (or unplug the cord with a dry object) before touching it. Then look for burns in the mouth, heavy drooling, coughing, or labored breathing. Lung complications can appear up to 24 to 48 hours later: have it checked even if it seems fine.
