Do any of you have recommendations on which kinds of food have worked best for your dogs and your wallet? Do you think it's possible to keep a lazy bloodhound and 2 energetic 11 month olds (retriever and cur) on the same diet? The hound gets fat if she even looks at her bowl, and the cur eats like a horse but can't keep still long enough to put on weight.

Also, has anybody found diet affecting energy levels and in particular hyperactivity? Or does anybody have any training suggestions? My retriever is in training for Search and Rescue, and has amazed everyone with her drive, but all hell breaks loose if she sees a flashlight or any kind of reflection (like from a mirror or CD). All she can think about is chasing it, including up the walls in my house. She'll run into people to get at it, and becomes selectively deaf when usuallyshe minds well. I don't know what to do for/with her, as it could result in her failing her certification test. Will she maybe outgrow it? HELP!!
