Dogs can have ice cream.
Ice cream is a good treat for dogs and they can safely eat some ice cream.
Just don't feed them ice cream too much because the fats and sugars could cause weight gain in the dog and make the dog unhealthy.
However when fed to the dog in moderation a few times per week or so the ice cream is a healthy treat for the dog.
Dogs can eat almost any other food that humans eat except for some foods such as chocolate and grapes.
They also make and sell ice cream for dogs as well which is made for dogs.
But dogs can eat the same ice cream that humans eat.
My dog eats some ice cream with me.
I remember even sharing an ice cream cone with my dog one summer as a 4 year old.
My brother used to do the same when he was 2 years old.
I don't recommend that but we lived and are healthy.
