You can serve it every day of week, hopefully rotate between 3 different proteins. It's a good idea to give him some vegetables too, preferably steamed, if you don't buy the mix that includes vegetables you can give steamed green beans, because it's filling, but I also give canned pumpkin ( not the pie filling one ) . Other vegetables are good too, just not onions. I like to thaw out individual servings that I put in zip lock bags, 24 hr in advance in the fridge . It can be served frozen too but my dog tends to throw up raw food so I think it helps a little to serve it thawed.It's always a good idea to thaw slowly at fridge temperature. I also like to microwave a little bit of water and add that to the raw food in her bowl to warm it up a bit and give her a little extra moisture in her diet and it also mixes up the other stuff I add ( organic turmeric, hempseed oil or flax seed oil, fish oil, Actiflex 4000, sea kelp ). The sea kelp is like a multivitamin if you only serve straight 80/10/10 meat. eg.
