Puppies grow fast, and their collars need to keep up. Here's how to stay on top of it.
First collar
Many puppies start with a lightweight, adjustable collar. Choose one that's adjustable, and check the fit often. Remember that it's only for the early weeks or months.
Check the fit weekly
Use the two-finger check every week or so. See how tight a collar should be. If it's getting tight, adjust it, or size up.
Signs it's time for a bigger size
- You've used up the last adjustment hole
- The collar leaves marks or flattened fur
- Two fingers no longer slide in comfortably
Growth varies by breed
Small breeds reach adult size sooner. Larger breeds keep growing for longer, so they may go through several sizes. Your vet can give you an idea of how big your puppy is likely to get.
When to buy a personalised collar
Many owners wait until their puppy is closer to adult size before buying an engraved collar, so the engraving isn't wasted on a collar that will be outgrown. In the meantime, a simple adjustable collar with a temporary ID tag works well.
Keep identification up to date
Even puppies should have identification, and a microchip is usually the first step. Local rules vary. Our country guides explain more, starting with Australia, New Zealand and the UK.
A rough timeline
Every puppy is different, but these are general ideas:
- First weeks at home: A light, adjustable collar for getting used to wearing one.
- Growth spurts: Check the fit weekly and adjust.
- Adolescence: Many puppies need a bigger size as they grow.
- Adult size: Once growth slows, you can choose a longer-term collar.
Your vet can tell you roughly when your breed reaches adult size.
Getting a puppy used to a collar
- Introduce it gently. Let your puppy sniff it first.
- Put it on for short periods with treats and praise.
- Distract them. Play or a walk helps them forget about it.
- Increase the time gradually.
- Check it often. Make sure it isn't rubbing.
Frequently asked questions
Should a puppy wear a collar all the time?
Many owners keep it on during the day and take it off at night. Ask your vet if you're unsure.
Is a personalised collar worth it for a puppy?
It can be, particularly once your puppy is close to adult size. Until then, an adjustable collar and a temporary ID tag are a practical choice.
How do I know it's too small?
Check the two-finger fit and look for marks or flattened fur. See how tight a collar should be.
How many collars will I need?
It depends on your puppy's breed and growth. Larger breeds may need several.
When should I microchip my puppy?
Ask your vet. Rules vary by country, so see our guides for Australia, New Zealand and the UK.
