How to Crate Train a Puppy

To crate train a puppy, make the crate a calm den in small steps: leave the door open with treats inside, feed meals in it, then close the door during meals and slowly build the time while your puppy stays relaxed. Keep crate stretches short, especially under 6 months, plan potty breaks around your puppy’s age, and never use the crate as punishment. That’s the approach VCA Animal Hospitals and Humane World for Animals describe, and VCA says most puppies accept the crate within a month or two.

Done well, the crate becomes the place your puppy chooses to nap. Done too fast, it becomes the place your puppy screams. The difference is almost always pace.

Choose the right crate

VCA says the crate should be just big enough for your puppy to stand up, turn around and lie down. Many crates come with a divider so you can enlarge the space as your puppy grows.

Make it comfortable with bedding and a safe chew or a food-stuffed toy. VCA suggests safe chews, stuffed toys and puzzle feeders for crate time.

The introduction, step by step

Humane World for Animals lays out a gentle progression. Move to the next step only when your puppy is relaxed with the current one:

1. Door open, treats inside. Toss treats in and let your puppy wander in and out. No closing the door yet.
2. Meals in the crate. Put the bowl near the front, then further back once your puppy steps in easily.
3. Door closed during meals. Close it while your puppy eats and open it as soon as the bowl is empty. Then gradually leave it closed a few minutes longer, building to about 10 minutes after eating.
4. Longer, calm stretches. Build to about 30 quiet minutes with you mostly out of sight before you leave the house or try a full night.

If your puppy whines to get out, Humane World for Animals says that usually means you lengthened the time too fast. Shorten it next session rather than waiting it out.

The free puppy crate training schedule has these steps, the potty table below and a daily log on one page.

How long can a puppy stay in the crate?

Less time than most people think. Two respected rules of thumb are both maximums:

Puppy’s age	VCA: about 1 hour per month	AKC: months of age + 1
2 months	About 2 hours, even overnight	About 3 hours
3 months	About 3 hours	About 4 hours
4 months	About 4 hours	About 5 hours
5 months	About 5 hours	About 6 hours

At 6–8 weeks, VCA says puppies need to go out at least every 2 hours, even overnight. And Humane World for Animals advises that puppies under 6 months stay in the crate no more than 3–4 hours at a time. Use the stricter number while you learn your puppy’s signals.

When to take your puppy out

The AKC lists the moments that predict a potty break: on waking, after naps, 5–30 minutes after meals, after drinking, and after play. Add a last trip right before bed. Taking your puppy out at those times prevents most accidents before they happen. If you’re keeping track, the free house-training log makes patterns obvious within a week.

The night routine

Put the crate in or near your bedroom, as the AKC and Humane World for Animals suggest, and take your puppy out right before bed. If your puppy wakes and cries, take them out, but keep it brief, calm and boring. VCA advises no play on night trips, so your puppy learns that night is for sleeping.

What not to do

• Never use the crate as punishment (VCA; Humane World for Animals). It has to stay a good place.
• Never punish accidents, rub a puppy’s nose in them or hit. VCA is clear that this doesn’t teach house training.
• Don’t rely on the crate for separation anxiety. Humane World for Animals notes a crate isn’t a fix for it; a behavior professional is.

When to call your vet

VCA suggests calling your vet if your puppy drools, cries constantly, tries to escape or can’t settle in the crate. The AKC notes that stalled house-training progress can be a sign of a urinary tract infection, and VCA suggests checking in with your vet team if your puppy isn’t progressing by 4–6 months. Most puppies are fully house-trained by about 6 months, according to VCA.
