There are lots of products which help discourage pets from destructively chewing household objects, and from chewing, licking and scratching wounds and bandages.
One of the most popular chew deterrents is bitter apple. Bitter apple is a formula developed by American Irv Grannick in 1960. Bitter apple formulas now exist for dogs, cats, birds, ferrets and small mammals like guinea pigs and hamsters. Bitter apple chew deterrents come in sprays, liquid drops and gels.
To introduce a chew deterrent to your pet, it can be helpful to place some on a rag or piece of paper, and then gently put it in the pet's mouth. She will taste it and spit it out, and will most likely want to avoid chewing any objects that the chew deterrent is sprayed on.
