I am going to be adopting a beagle from a friend soon. She is quite over weight and was hit by a car last spring and ended up with a dislocated hip. She's doing very well but I want to take some weight after I get her. She is an average size beagle. I'd just like to have an idea of an approximate weight she should be. She also has some arthiritis and I think she'd get around a little better if she lost some weight.
