Changing flavors of food every bag

[Haley, Yeti, and Phin]

We are feeding Yeti wellness simple. We started out with the salmon and potato however I think he was getting pretty burnt out on it. We switched it up to the lamb and oatmeal and he is gobbling it down in minutes. I know he just likes it right now because it's new. He will probably go back to his old ways in a week or two and that's okay (we're used to having to sit with him for 10 minutes encouraging him to eat). My question is, is it okay to switch flavors with every bag we buy? We usually order the big bag (26 pounds?) off chewy and it takes him around a month and a half - two months to finish it (depending on if he eats his whole cup at each meal or not). I was hoping that switching flavors might help keep him interested in his food longer.

After all of our troubles with Yeti not eating anything but his bland diet we are VERY skeptical about giving him add ins. We don't plan on it, but you never know if you need to kennel and we don't want to get ourselves over or heads with his eating patterns lol. He does pretty well with the wellness and we give him kongs and homemade frozen dog treats :).

I think you're being very wise about that.
