I have an 8yo pomeranian who is overweight. The only exercise she gets is a daily game of indoor fetch. I'd like to take her for walks, but whenever I do she develops a limp that lasts for at least a couple hours. Her diet consists of dog food (we free-feed), egg yolks, and several dog treats daily. Given these facts, what's the best way to get her weight problem under control--diet or exercise? Thanks!
