Our dog loves chasing ice cubes around on the kitchen floor..it's hilarious to watch him trying to pick them up too! You could also try freezing some chicken necks or bones in some water or chicken/beef stock. Will keep her occupied for a while, and also provide some liquid and some food for her.

We also got one of those shell pools for our dog (we got ours 2nd hand so it has a hole in the side which we must patch up so we can fill it up more!) one half of it is filled with water and the lid bit has some beach sand in it, he has free access to both of them all day and loves jumping in the water when we come back from walks in the morning. He has a long coat and has been quite hot, I let him inside when I get home from work, I'm just glad he is gold, not black otherwise I would feel even worse for him!
