Whether you have a puppy or a dog, you cannot allow them to bite.
It is a behavior that must be corrected as quickly as possible.
Aggressive dogs can be a menace and leave you wanting to get rid of them.
Before you take any extreme measures try to fix the problem.
Get to the root of your dog's biting problems, observe your dog and recognize the reason for each one of their biting incidents.
He may bite as a reaction to a certain family member, strangers, another pet, a noise, or it may be playful biting.
Observing your dog more closely may even expose that your dog is not to blame.
If your dog only bites one specific person you may learn why.
Such as if your child or another pet is aggravating or tormenting the dog and leaving it to believe that it must defend itself.
If you understand the reason for your dog's issue, it may be easier to overcome.
Getting your dog to stop biting can be frustrating, but it is a very important action that needs to be corrected.
It's embarrassing, stressful, and annoyed to have an aggressive dog that bites.
When you think your dog is about to bite say "don't bite," "no," or some kind of simple command to correct them.
If your dog already bit you, say "ouch!" even if it was a little nip that didn't hurt.
Make your dog think that they hurt you and then ignore them and have the rest of the family do the same.
Be consistent and never let your dog get away with any nip or bite.
Your dog must know that you are in control, that you will not accept such behavior and also that you will not give up on ignoring them until they act properly.
If you know what triggers your dog to bite and they do not bite when that trigger occurs, praise them.
