Ive posted on here before that Colby is a picky eater. He pretty much doesn't like most kibbles. I make a home made chicken/rice/egg mixture and add Stella and Chewy's freeze dried chicken mixers to it. We also give him a puppy vitamin to make sure he is getting all his nutrients. Until I found this, mealtime was a fight with him. He'd go on hunger strikes. You might want to look into Stella and Chewy's its a good brand. I also found this website:
Dog Food Reviews and Ratings | Dog Food Advisor they are a good place to see what you are feeding your dog, what is in the food, and how it stands up against other foods. I has helped me choose. Good luck!!
