Stopped eating it again

Last year my 2 German shepherds loved this food. We were so glad to find something they would eat. Then at the end of 2022 Hills was out of stock for months. Then Hills started supplying it again and they would hardly eat it. It has gotten worse with each bag to the point they are starving themselves not eating it. Why do these companies have to change their formulas? Of yea I forgot its all about them making money and our pets suffering. I will just keep returning it to Chewy. Chewy you need to speak up.

Nessie won’t touch it

Nessie is a very picky eater and has allergies so her choices are limited. She loves the bites of salmon I give her when I eat it but dog food salmon must be a lot different. She won’t even try it.

Not for my dog

This is my 3rd bag of different varieties prescribed by my vet. My dog is drinking 3 times as much water than usual and having more difficulty with pooping. Her skin is no better as a matter of fact seems much worse. More dandruff more paw licking. Maybe it’ll work for someone else’s dog not my Daisy.

My dogs will not eat it

I purchased this by vet recommendation due to a white haired Maltese who seems to have year round allergies (ear infections and irritated paws). The idea was an elimination diet, but after eating it twice, she won’t go near it anymore. My Pomeranian appears to feel the same way. Normally the Maltese turns in circles when it’s time to eat, now she lies down or goes back to her bed if I put this in her bowl.

My little Coton is t quite taking to it yet. She usually is nuts over salmon treats, but those are mostly freeze dried fresh salmon, so not sure if she will like this. Should of tried a small bag instead.
