Did the formula change??

My dog has done great on this food for over a year but the last two bags she has been farting NON STOP!!! It’s so bad!! I’m talking run you out of the room farts

My dog has done great on this food for over a year but the last two bags she has been farting NON STOP!!! It’s so bad!! I’m talking run you out of the room farts with every move. Nothing has changed in her diet either. She still does ok on the food but I’m considering switching just so the humans in the house can get some relief.

Auto delivery too soon

I ordered a bag before auto delivery date. I then changed the next auto delivery date to several months out instead they delivered on the old auto delivery date

He like it, which is a win for kibble with my dog

My dog is a grazer and really only eats his kibble when he is truly hungry. I was very pleased that he immediately started eating this without turning his nose up

My dog is a grazer and really only eats his kibble when he is truly hungry. I was very pleased that he immediately started eating this without turning his nose up. Bonus is that it’s fairly affordable and addresses kidney care.

She actually really likes it!

I was afraid she wouldn’t eat it since it was prescription food. The price is a lot better than other brands. I hope her renal function improves when they do her

I was afraid she wouldn’t eat it since it was prescription food. The price is a lot better than other brands. I hope her renal function improves when they do her labs at the vet again.

Kidney protection

Our furry child was not absorbing protein properly and spilling a lot of it in his urine. Since being on Diamond Care only a short time, we gave already seen improvements
