The skin infection might be the result of an overgrowth of BAD bacteria:
Candida
Yes, do some research and start to give them some Probiotics. I bought my in the Vitamin store (in the fridge section). I keep mine in the freezer for freshness and to last longer.
The brand I bought is Udo's Choice - Super 8 Probiotics
They are capsules and I sprinkle a good amount daily onto a spoon of Danon Activa Yogurt.
I hope you are able to help them heal, those pics look like they are very uncomfortable.
P.S. Since you say your Vet has tried everything, maybe you might want to consider a Holistic Vet, maybe they could help??? just an idea
P.S.S. I am also feeding Organic Virgin Unrefined Coconut Oil to Roxy and TJ. It is suppose to have wonderful ALL around health benefits.
Google: Coconut Oil for Dogs
see what you come up with
