My 20 year old sheltie stopped eating. Now I realize he is old and his days are limited but I wanted him to eat. Turned his nose up at everything, I mean everything. My local grocer just put this in the pet aisle. I bought the smallest roll and gave it a shot. He smelled it for a few minutes and to our delight he ate it. It’s been a week and I notice subtle differences, his potty breaks are easy for him and I notice him walking more. My guess is he just feels better. Thank you for making this food.
