What is bitter apple spray for dogs?

Bitter apple spray for dogs is a chewing deterrent. Spraying it on a dog is supposed to keep the dog from chewing on his skin if he has a wound or hot spot that he feels compelled to tend to.

Bitter apple spray can also be used to keep dogs from pulling at their hair, and it can be safely sprayed all over the body with the exception of the eyes. The spray puts a foul taste in the dog's mouth, keeping him from chewing at specific areas of their body or paws. Many pet owners also use bitter apple spray on household furnishings to discourage their dogs from chewing these objects.
