Hmm, that is strange. Could it be possible that he cut them somehow at first and now that the pad is separated it just gets worse in the summer when he is more active outside?
I'm picturing the part of the pad to be similar to the extra thick skin we have on our toes and fingers around the nail- it's thick and doesn't hurt when you trim it- does that seem like the same thing for his pads?
I wouldn't consider amputating unless it was bothering him or infections became a problem. Will he leave booties on for a week or two and see if that makes a difference? Keeping the skin protected may help it heal faster.
