We have just picked up our new baby last night. He is extreamly skinny, much thinner that his pic. He has been tested for worms, neg. He was being fed Science Diet and we are putting him on Candiae today. My question is... are there any concerns with changing to a high quality food. Is there a right way to do it or do I jump right in. Also, are there supplements or anything I should consider in order to help put some meat on his poor bones. He is 12 months old and I can see his ribs and hip bones at all times and his back bone is prominate when he lays down, I can count the vertibre. Any advise will be greatly appreciated as I am off to the feed store after work.
