As far as your pup not growing, is it possible that since you see him every day you are not noticing it?? Also, you do not want him to grow too fast as that adds to joint problems. California Natural is EXCELLENT food, so is Innova, both made by the same company. Human grade meat, the animals used are not pumped with hormones and the vegtables are not sprayed with pesticides. Good luck and keep us posted on your puppy!
