I have an 11 year old springer and up until the last handful of months had always fed him purine pro plan sport 30/20. Switched to a grain free salmon that is Kirkland brand from Costo, belive it is made by Diamond. Switched since he has having a bunch of mysterious skin issues. Food didn’t seem to change it, but we now have him on a supplement that has taken care of he skin issue with success (Dr Oakley’s better wild bindi bites). After switching the amount of poop that he produced has tripled so I am assuming the kirkland brand is a lot lesser of a food than the Purina.
He is a lot less active than he used to be so don’t really want to go back to the pro plan sport 30/20. What are you guys feeding your dogs and roughly what is the price per pound?
