Teddie is a picky poodle.

It was not the food. I am still looking for a food she will eat. She doesn’t eat this. She will leave her food and eat her sister’s, which is puppy food from Hill’s

I am not happy with my purchase, the delivery box was not damaged but the dog food bag was ripped and food was all over beneath the bag so at this point I don’t know if who packed it knew it was rapped and decided to still send it like that, I would like a exchange

No corn no soy no wheat

I decided to switch to this after they changed an ingredient in their adult dog food. My dog can’t handle the barley it kept giving him diarrhea. He has been eating the puppy bag which is chicken and brown rice. I’m not sure why they added the barley but I had to find something that didn’t give him diarrhea. This is great and he loves it. If your dog has issues with the chicken and barley I suggest this bag!

Ah, Dagger Is A Little Picky With This

I just transitioned Dagger off the puppy formula and assumed this was pretty much the same flavor for adults - he just turned a year old - but he is usually a walking

I just transitioned Dagger off the puppy formula and assumed this was pretty much the same flavor for adults - he just turned a year old - but he is usually a walking vacuum cleaner with food and he's turning up his nose and walking away. Then he goes back to his dish, finally, probably because he's hungry. I am going to shop around with other flavors to see if something looks more appetizing. I wish he could talk!
