My Frenchie has been suffering from interdigital cysts since he was born, he is 2 now and we have tried everything. Changed his diet, shampoo etc,. creams, he's been on antibiotics and atopica and none of it works. The specialist dermatology vet says that he should undergo laser therapy. Basically the laser heats the skin protein filling the cysts to extreme temperatures causing the cysts to vaporize and disrupting many other cysts. Has anyone heard of this or had this done? It sounds drastic to me and I'm quite concerned.
