try finding a different vet. i cant believe there are vets that still use mitaban dips. there are way better treatments available. my vet uses oral ivermectin, an antibiotic, and an oral antioxidant.

your vet told you the dog could not have antibiotics because it was recently dewormed? thats a load of crap. find a different vet. as far as your puppy being depressed, its from the dip. the dip is sulfur based and can burn, irritate, and dry out the skin. it also can cause pets not to feel well.
