Sorry I missed this Jules. I am glad she's feeling better.
On a side note. While I never thought Keegan was overweight - my vet did they just didn't say anything until her annual checkup and when I brought it up. She has now lost 15 pounds!
You would know if she is uncomfortable, Keegan when she started showing signs of dysplasia she was slow to get up in the back end. If she wants pets from and people are close enough to do this or to just watch people she spins on her butt. My vet had never seen a dog do that before until our last visit. But I am so used to her doing it I didn't think anything about it. It is just a way she has compensated herself.
Good luck to sweet Daisy.
