Jake had his first official vet visit Tuesday and he was a good boy! The vet found that he has some Demodectic mange (not contagious) and wants to hold off a few weeks on heartworm treatment. Jake will be continuing his Doxycyline antibiotic, and is now on progressively increasing doses of Ivermectin. From what I've been told, vets are trying to prepare dogs for heartworm treatment slowly instead of giving them one big blast of meds. Apparently it poses less of a danger to the dog. I'm not vet but it sounds logical to me... His skin and hair are slowly getting better!
