Hi -- I have an 11 month old 1/2 husky + 1/4 border collie and 1/4 lab mix. He weighs ~45-50 lbs and is neutered. He is a very picky eater and I have tried every premium dog food out there... science diet, performatrin ultra, viand, fromm, acana, etc. I have tried all different protein sources, limited ingredient, grain free, etc. I have also resorted to using a tsp or two of canned food (Merrick, Kirkland, Tripe, etc) to make the dry food more novel. My problem is that he will maybe eat the food for 2 days and then he refuses to eat any of the food. Naturally I am worried because he gets about 3 hours of exercise a day (dog park, bike and walk) and he is still growing. I give 1 small treat a day after our walk and that is it -- i'm taking the tough love approach. He is perfectly healthy -- was just at the vet for a checkup. Any advice would be very much appreciated. Thanks!
