Hi

My puppy is 8 weeks old and she would not eat any of her food, its so bad she's lost a lot of size that her bones are showing, don't get me wrong she is really active running around and stuff. We currently have her sharing a cub with another puppy who growls sometimes when she is going to eat. Do you think this is what's causing her to not eat?:)

Little one is being out competed (is that a word?) for food. You need to start training both pups that their food dish is theirs, not the other one's. Yes they need separate dishes.

Feed them completely separately...

At 8 weeks they should not be sharing a food dish any more, all that is doing is making them food aggressive.

Dogs should be fed out of separate bowls. I have 4 dogs... they each have their own bowl.
