Husky hot spots?

My husky has been scratching/biting/liking at his paws all the time. He has a huge bald spot on his behind that is bright red and another one on his side. I don't know what to do, I took him to the and they said it could be right worm so they gave me this "Lime Dip" and that didn't work. I've looked everywhere and all I could find that looked like it was hot spots. He's going crazy scratching all the time that he rips his hairs out and he's always so thirsty. I need help! I'll be taking him to the vet soon I just need someone to help me so I can understand what's happening. I love him very much  and I wouldn't want anything to happen to him. Thanks!

It certainly does not sound like ringworm. More likely a hotspot though I am concerned he is drinking so much. Excessive drinking can be due to several conditions but there a few hormonal disorders that also involve the skin. In the meantime, see if your local pet store has a topical antibiotic and cortisone ointment or medication. This in now way will replace you going to the vet but it will improve your husky's comfort until the day of your vet visit.
