Good thing they're outside
I wonder how safe that is...
Aside from possible upset tummy from lactose intolerance and sugar, not much. Just don't give them hella ice cream all the time and nothing they couldn't otherwise have (cherries, chocolate, etc).
Gotta be careful about some sweeteners too. Xylitol is pretty toxic to dogs if I recall correctly.

Kinda reminds me of the pup from The Sandlot with all that white slobber foam
