Good afternoon and welcome!
I give my Otis grizzly salmon oil in his dry food as supplement. Toy's - he loves deer antlers and balls, any soft toy is destroyed before we know it. I also give him broccoli, carrots and popcorn for treats. As far as food I just switched to California Natural Grain free kagaroo and lentils because I was having constant ear infections and this food has no potatoes, yeast and is low in protein (good for his weight)
Best of luck to you!
