Things You'll Need
- Mackerel, fresh raw or canned
Instructions
Buy mackerel. This can be fresh from the fish market, or canned from the supermarket. Be careful what canned mackerel you choose however, as some are full of salt. Simply drain the juice from the can if this is the case. Also, choose one that is high in fat which will help with weight gain.
Mix some mackerel in with your dog's dry food. Give it as a meal.
Feed your dog mackerel once a week, or every other day, depending on how much weight they need to gain. If they don't seem to like the taste, consider putting fish oil capsules in their food instead, as mackerel is a key ingredient in fish oil.
