When it comes to introducing your puppy to a brush, you should make sure that they’re 100% settled into their new home first. Once they are, you can start the brushing process!
Start while your puppy is laying or sitting down and speak to them gently while brushing. Reward them with treats and lots of reassurance to help them understand this is a good thing. If you’re struggling to keep your puppy still, you can get things like puppy Kongs or lick mats to help distract them.
