Hi Jennifer,
I have a beagle cross which I rescued 7 years ago. He is now eight years old. When I first got him he scratched himself and bit his legs until they were bleeding. After many visits to the vet they finally did allergy tests and found he was allergic to beef, chicken, duck and just about everything growing. I tried fish, lamb and turkey based grain free foods. They helped a bit but he was still scratching a lot.The vet prescribed atopica capsules which worked well for ages but then started to make him a bit sick and lethargic. so stopped them.A friend suggested yumega oil. I bought a bottle over a year ago and put a measured amount over his dry food every night. He has stopped scratching and biting his legs and his coat is looking great. I also give him a monthly bath using ruggle-it shampoo which works a lot better than the malaseb from the vet. I hope this is of some help
