MY dog walker suggested it to me. Not sure it would work with Thumper since he has kidney issues but it could work for Bella.
I also am concerned about the cost. I know in NYC there are a few Petco locations that have displays of justforfood and they do demos so you can bring your dog to try it out.
I think I am going to stick with what I use since it seems to be works.
