A few weeks ago I asked how to keep my dog cool in this heat. I was suggested a little plastic pool. And now that I have enough money(after babysitting a few times) there was just two things that I was wondering about, one around what is their price in Cananda. And the most important since I know rex is afraid of many things having to do with water how should I go about introducing him to the pool? I was thinking may be what is called a water wubba?
