It's cheesy ice cube season! (cheap fun hot weather treat)

When Bugsy was a pup we had to be very creative in thinking of things for him to chew that were inexpensive, renewable, low in calories, safe and easy to always have around.
Somewhere someone mentioned making large ice cubes for him to munch on. So I filled the bottom of a 32oz yogurt cup with water, froze it and gave it to him by placing it in his pool. This way he had to catch it before he could eat/destroy it and it cooled him off in the process.
As he matured he wasn't too interested in the plain ice cube. He'd go get it from the pool but he wasn't too interested in it afterward. So I got a bit more creative and took a cheese stick and broke it into pieces which I added to ice cubes and water in my 32oz yogurt cup. Wala he was totally interested again. Now he won't leave the ice cube alone until he has de-cheesed it. And if he feels like it he eats all the ice too.
"hmmmmmmmmmm dis iz good!"

So if you want an easy treat and time consumer for your pup, try this. You might use a little beef or chicken broth in the water or cheese or whatever you like to make it interesting. If you use the broth only use a small amount as the salt content will be high.
You can choose whatever size is appropriate for your pooch.
I've attached some pictures below of Bugsy enjoying his cheesy ice cube earlier today. It was too hot for fetch so this was an easy cool form of entertainment for him.
