hello everyone . i have 2 dogs a lurcher cross and a dear hound , the lurcher got mange so took him to the vets who gave me a 2 month course of skin drops , hes lost most of his fur on his legs and under belly , the fur doesnt seem to be coming back , now my dear hound has got a few patches on her legs she is booked in on friday to see the vet , does any one know of anything i can put on them to help there hair to grow back , i was told by someone to rub diesel oil on them but im not to sure about this . any ideas
