Hello, first of all I'm planning on getting a family pet in the near future, I'm currently torn between, labrador, german shepherd or a husky (all beautiful). I'm also intending to go down the raw food route or barf diet. Being a keen angler, I catch lots of mackerel. I'm thinking this would be a low cost and very healthy diet. But obviously I'd like to provide a balanced diet. So how many meals per week could i feed frozen whole mackerel? All advice appreciated.
