Food geared for older dogs.

My "Old Boy" is 13 so I've started feeding him this age appropriate food. He likes it and it's better for him. What's not to like?

Lily couldn’t tolerate it. Threw up with an hour of eating it

Unfortunately Lily had one serving and threw it up. She was suffering from cancer and we had to Put her down yesterday. Such a sad time for our family right now
