I am trying to get my dog off his RX diet of Hills Low Fat ID. He has been on it for a few years now and it has really helped his reflux but I really want to get him on something less full of fillers and more healthy but he struggles whenever a kibble has high omega 3 oils. I notice if the oil content goes over 2% it really causes his reflux to go nuts. Does anyone know of a good food for a senior dog without the high oil content? I’m struggling. Any thoughts? I’m also curious as to what amount of protein a senior dog his size should be getting? He’s 11 and he’s 25 pounds. He’s a dachshund terrier mix.
