My breeder was feeding Iams super puppy so when I got him 3 days ago I put him immediately on Canidae (only 2 meals supplemented a bit with the IAMS). I heard of Pumpkin being a solution to diarrhea but was wondering where to get it and what to look for? His stool is a bit loose right now and sometimes watery so I'd like to offer this to him temporarily. Secondly, is it okay to feed yogurt such as 'plain' flavor to him with his food? Finally, Canidae doesn't seem to mention it has glucosiamine in it for joint health but I'd like to start early to optimize growth and hopefully prevent long-run arthritis. Any supplment I can add? Once again, thanks everyone.
