How much should our Lab pup eat?
I currently have a lab that is 10 weeks old and eats 3 cups of dry food twice a day. The sucking is her trying to imitate feeding from her mother. If you puppy is only 8 weeks old and depending how long you have had her at you home depends alot on how she acts. She may be lonely from all the other puppies. give it some time she will eat when she is hungry. Over time she will get more comfortable with you. The only thing I can say is to stop switching food so often and ask a vet if she stops eating for more then a day.
