Does anyone use county dog food premium hypoallergic grain free. I am usi g a third of a tray of this as a topper to fishmongers finest. My jack Russell mix seems to like it. I calculate the amount so as not to overfeed him. My mole valley store is nearer to me. I was also wondering whether to change his kibble to country dog. I have a months supply of fishmongers finest to use up. He is a year old. Any advise please. He was on fishmongers finest puppy food until it was difficult to buy due to lockdown.
