I feed my 12 week old Aislee, Wellness and she loves it! Does anybody know how much a 1.9lb puppy should be eating? She eats 3 times a day- sometimes up to 20 pieces of kibble at each meal. Is this normal? Sometimes she'll eat more than that...I've read a ton of books and they just tell me how many times a day she should be eating for her age, not how much. Help?
