I agree with the above, just wanted to add something to ponder.
Wellness is rather a 'rich' food, my dogs did not do well on it, and I know a few others that didn't either, mainly diarhea..So maybe, just sayin,,I would try switching the food as your thinking.
I like Vetericyn for rash/wound all around care..While I am NOT a fan of purina, I did put one of my aussies on it PUrina SS, sensitive skin/stomache for a time,,he gets 'fungal' sores during certain times of the year..cleared them up great, his coat was gorgeous, stools were great, BUT, he porked on the weight,,so I discontinued it..I did like the food, it was salmon based..
Hope you can clear things up, I don't really have any advice on the antibiotics but I DO like using probiotics..
