Well.. Riot has ALWAYS been a finicky eater. While we were at the cottage, he was extremely active going on hikes daily as well as long swims daily. He gained a fair amount of muscle in a week - BUT he also lost a significant amount of weight. I had doubled his food intake while at the cottage knowing he was going to loose weight the way he was so active.. but it didn't work very well for him lol What can I suppliment into his food that will help him gain weight. Hes at the point where I can feel ribs and half of his spine (although in Belgians feeling a slight bit of spine is acceptable for showing). Anyways, he is being fed "Fromm Duck and Potato". He likes the food - but only eats small amounts at a time. Right now I'm giving him 2 tb spoons of Eagle Pack Lamb formula mixed in with his 2 cups of Fromm twice a day. So far he is eating it. but, I dont like canned food for him. I noticed when he was younger he developed plaque quite quickly when given canned food even with daily brushing. Is there anything else that would be healthy for him to have mixed in with his dry food???
