I have 3 dogs, my main concern is my Cavalier she has a murmur asymptomatic, but i want to get her on the best food to prolong any issues that i can, one dog is has just general joint stiffness. Zignature was suggested but its high in sodium i guess.
Do a search here for “low sodium” Another poster, some time ago, did the work for you on finding low sodium foods. If you aren’t opposed to feeding raw, you might want to add a bit of heart to your dog’s diet. Heart muscle is a good source of taurine, which they have found Cavs need.
