Ever had to deal with E-Collars? I know I have, when Jr. gets hotspots, I have to put one on him so that he doesn't chew on it. I definitely don't like them and Jr. doesn't like them, but I was reading an article about an alternative for the e collar.
The alternative is called a Pro Collar, full name ProCollar Premium Inflatable Protective Collar. They are available at supply stores and some vet clinics. Its definitely a good idea to consider seeing if this might work for your dog if you have had too much trouble with e collars before. Although as with most everything, this isn't good for all dogs. Nor is it a good idea to use if if the area you don't want the dog (or cat) to touch is on his/her head, as they can easily scratch it with their paws. Also some dogs might be able to wiggle themselves out of these.
Here's a link with the article, pictures and prices. What are your thoughts on it?
