Here’s a really simple dog training tip to stop your dog play biting without punishing him (e.g. by putting him in a crate). This tip was taken from the Dog Training Planner.
Outcome: Stop your dog biting
Your puppy is likely to nip or bite because they’re teething. It is important to remember not to punish them for this behaviour as this can make the problem worse. Remember to give your dog appropriate teething toys and try these two step plan to stop your puppy from biting.
Step 1: ‘Ouch’ or ‘No’
Every time your dog bites, or nips at you, make an ‘ouch’ sound. It needs to be loud enough for the dog to hear, but make sure it isn’t aggressive or punishing in any way. You want the dog to realise that biting can hurt you. ‘Ouch’ can also be replaced with ‘no’ or a command of your choice.
Step 2: Teething Toys
Whenever your dog begins to bite or nip, distract them with a teething toy. Repeat this until the behaviour stops.
Puppies may often bite, or nip, because they are teething. Be sure to have teething toys available and do not punish your dog for biting. It is important to shape the behaviour you desire with positive reinforcement.
