You might want to pick up some Sam-e at WalMart and give it to your dogs for a few weeks, add some B-50 complex (you need a balanced B with Sam-e).. it will help detox the liver. Good for you homecooking. They don't need kibble anything, dog's don't need grains. Just remember to add some ground egg shell for calcium 1/2 tsp per pound of meat.
Thank you for your help.
