I would highly recommend the fish oil. As I stated before in a previous post, I put Zak on a grain free diet and added fish oil pills daily and a Cosequin DS (glucosamine & chondroitin) capsule sprinkled on his food each day for arthritis and he has not had a problem with arthritis since. There are foods with these supplements included, however, it is my understanding that they are just sprayed on the food. My vet had in the past suggested for my senior dogs at least 1000mg fish oil daily for cognitive health and the arthritis. For Zak and some early kidney disease he is showing she is recommending, and I have also read on line, 100mg fish oil per 10 lbs. of body weight (2500 mg daily). I don't think you're going to find the best level of fish oil supplement in a kibble. Oh, and his coat this year is sooooooooo soft! :)
