One of my least favorite topics. LOL I'd say they are prone but skin problems seem to be a problem for most dogs where we are.
The first thing I'd do is an allergy test. Sometimes the results are surprising. We had a girl whose problems were greatly reduced by not giving her cotton blankets, which is what we were doing before finding out she was allergic to cotton. (Being cuddled by someone wearing a cotton nightgown likely didn't help either. LOL)
The next thing I'd do is wash their paws after they've been outside. We've had good luck with that.
Finally there are some topicals that can help. I think we've used Vetercyn (sp?) and at least one other. They don't seem to help as much as the washing but sometimes you may need to calm things down. You might ask your vet what he/she recommends.
The cone of course sucks. We've also tried ace bandages and similar. All of which were not ideal solutions.
