Penelope is refusing to eat her puppy kibble. She will eat anything else, just not the puppy kibble. Yesterday, she threw up because she had an empty stomach and would not eat. So, I did have some canned version of her kibble I got from the breeder when we picked her up. I was only to use it if/when she wouldn't eat. I was to mix in a little bit, about a tablespoon, with her dry kibble. Well, I had to do this both times she was fed yesterday. She ate it then. I don't want that to become a habit (the wet food, was also an adult form). So, what should I do? Is it time to switch foods, is she ready to move to adult food (the breeder actually would start them on adult food at 4.5 or 5 months, she said they didn't need the extras in the puppy food by that time), not sure if that is right, but she has been breeding champions for 30 years. Or, what else do I do? Also, if it is time for a switch with the food, Saturday she is going to spend the week with my mother and sister-in-law while we are in Mexico. Not the best time to make a switch. She will just sniff the food and then turn her nose up to it. I'd appreciate any help!
