Brain Freeze in Dogs

My Australian Shepherd loves to eat ice cubes. Every time I get some ice, she trots over and asks for one. Sometimes I give her several in a row. She never seems to suffer the dreaded "brain freeze" or "ice cream headache. So I began to wonder - can dogs get brain freezes? Does anyone have any experience with this? How about dogs getting just headaches in general?

Actually, dog trainers teach owners to give ice cubes to their dogs when they are at work, because they can't let them outside "to go" until they come home. Restricting their food in the day will make them need to drink less water, and the ice cubes give them enough liquid without filling up their bladders too quickly, therefore less potty accidents are made in the house. There hasn't been any reported cracked teeth from chewing the ice cubes (yet), as that's what would concern me... so it should be okay! : )

:) interesting I have never tried to give my dog ice cubes. I had poodle 3 years ago, he liked ice-cream ,very much, he was 14 years old but I have never notice any problems with him :)
   
So, I think ice cubes won't effect badly :)
