Never heard of it but spin it around and see what the first line ingedient is. If the first is corn then there is the start of your problem. Also look at protein and fat content to see what level you are feeding. If you hunt em hard gonna have to have a quality feed in em to keep from burning up their energy and provide stamina. The other posts as far as supplements on here are also good advice coupled with their diet. Good luck with it bro.
just because it says 28% protein does not really mean the dog is actually eating 28% protein in some cases especially with the cheap feeds. It could be 18% quality digestable protein and 10% hair (hair is protein) which is not digestible. Same with Bone it is calcium but is not digestible. Be careful with the cheap feeds. The bag must say 100% nutritionally complete if it is a quality feed.
