Our dogs stoped thought about what happened and then went right back. Kind of funny to watch but not very effective.

Pros: Will make the dog think

Cons: Didn't stop the chewing

I used this when my dog had a paw licking problem. I would spray it on her paw and in about a week she stopped. I use it on things my cats like to chew, too.

Pros: Easy to use.

Cons: none

I have had great results when using this with dogs but haven't with cats.

Pros: great for dogs

Cons: haven't known it to work for cats

One of my cats was going to the bathroom behind a chair. the bitter apple kept her away and we were able to retrain her.

Pros: kept cats away

Cons: too strong a smell at times

my cats always chewed my books now I spray bitter apple and they have stopped also worked on the dogs

Pros: kept cats off

Cons: none
