HELP - I also posted this on the General Forum

Please take the time to watch this video of my Bully Ethel. She has been scooting around like this - the vet checked her out and does not think she is in any pain. She does jump up and run around with the other 2 dogs too. He told me to get her off puppy food and to cut down on her food intake. We did and she only lost 1 pound. She is a bit overweight for a female. she is now 58 lbs. He tried rimadyl for a week to see if there was any pain and she was the same. she runs and plays without limping, so is she just fat and a little lazy??? her one leg seems to be tucked under her big belly????
Thoughts please.....
