My dog Smokey is 10 years old and had been eating ole roy for a long time. It was cheap for my parents to buy. He recently started limping really bad and I found out that he was arthritis in his left elbow. My vet gave me some tablets and we tried those but they didn't help. So my dads gf got him some liquid medicine called finish line. I started doing research and found out about all the stuff he should have in his diet. So I have been giving him Chicken Soup for the Dog lovers soul (senior dog formula) I mix his finish line(2 table spoons) with the canned chicken soup with the dried chicken soup in the mornings. I wanted him to have more Glucosamine and Chondroitin. He really likes the dog food with the canned, but wont eat much of it when it just plan dry. He hasn't been on it long, but he does have Diarrhea. Is is because of the switch of food. I did mix the chicken soup with ole roy so it wouldn't be a total switch. Has anyones dogs benefited from Chicken soup? I want his elbow to get better. Please any advice or personal experience??I just switched his food 7-5-09. Also i didnt switch gradually witch wasnt good. I just learned that yesterday. I just poured the left over old into the new bag.
