When I notice something may be wrong with our dogs, I immediately do an investigation. Yesterday, our hyperactive pug Pipoy was limping and later it looked like he couldn't use his left front paw. I thought that it may be due to his long toe nails. That's a problem with Pipoy, he hates the nail trimmer and he goes berserk upon seeing it.
But I know that I had to do something so I checked on his paw. And there it was, a boil in between his toes. I called up the vet and I was assured that the boil will erupt and heal by itself. True enough, last night, there was blood on Pipoy's paw and surely that was the boil that erupted. This morning, he looks okay.
