tinned fish for dogs

Question
we have found out that our 14 week old German shepherd pup loves tinned mackerel in olive oil. what we would like to know is how many times a week can we or should we feed it to him. At the moment he is eating dry food with some puppy meat in jelly mixed in because he won't eat dry food on it's own.

Answer
Canned mackerel is an excellent fresh food source of Omega-3's so it is a great addition to your puppies meals! 2-3 times a week is enough and you can also alternate with sardines, salmon, and other deep water fish. I would recommend feeding fish canned in water instead of olive oil.
