anti chew spray sprayed to item he chews and ultra sonic bark breakers. Sorry I have not tried the positive things. But I have used these. With 10 dogs in the house it is sometimes hard to catch which dog is doing the chewing or barking (if one barks then they all seem to bark anyway.) Pam had problems with the ultra sonic bark breaker as one of her older yorkies was distressed by it. She would cry and was glued to Pam's leg. Not her usual behavior. So she sent hers back. |
