There's a reason why Daisy gets first dibs on ice cream, and it isn't because Cooper is a gentleman who lets his lady go first.
Judging by this video, in which the two dogs share an ice cream cone (though given Cooper's appetite, "share" seems like a stretch), Cooper goes second because he has a bit of a problem with portion control.
Don't worry, Cooper. Many humans aren't much better at sharing the frozen treats.
We don't advise feeding your dogs ice cream, as many have trouble digesting the lactose and can become sick. However, if you do, the ASPCA recommends sticking with small amounts and steering clear of any chocolate flavor.
