I was wondering if anyone can help me out. What can I add to Dukes food to help him develop muscle or even just put on some weight. I dont know Dukes exact weight/height but hes the height of a tall lab and maybe weighs 60 pounds at most. You can't see ribs but he does look very lean and could easily add 10 pounds and not look different. He doesnt eat much at all. He free feeds and eats when he feels like it. He maybe goes through 2 cups a day give or take, and hes just over a year. He does have a very sensitive stomach any food with too much fruits or vegetable makes him very sick and gives him diareaha for days on end. Right now he is on Performatrin (sp?) and does wonderful on it, coats great/energy level is awesome, very healthy. He is very active and we spend easily 2-3 hours offleash running around. Is there anything I can add to add weight and also help develop his muscles?? Reading around on the food thread I noticed people give there dogs eggs? What does an egg do for them? Thanks for reading and any advice would be great.
