Do Dog/Cat repellent sprays in reality work?

I'm having animal-on-furniture issues and was wanting to know what I could use to repel them off the furniture. I'm undo to any suggestions. It's hard to catch the dog on the couch but I know he jump up there cuz the pillows are not in the same place.

Answers:    Are you conversation about stuff like "bitter sprays"? I don't know if it works on dogs and cats, but my friends tried to use it for their rabbit, and it did no fitting. The rabbit loves to chew on cords, shoe laces, paper, just approximately anything on the floor. They used a bitter spray, she actually licked the junk rotten like she enjoyed it.

Unfortunately, it depends on the animal. My family have an older siamese cat and it worked fantastically when sprayed anywhere. However, I have a tabby kitten and she doesn't care what I spray where--though she will avoid it for rather while after I spray, as soon as the spray settles she is back on the couch.
