extreme temperatures seem to be normal these days. We've had some pretty hot summers already! This intense heat can be tough on our dogs, especially those with thick coats or older dogs. To help your four-legged friend, you can let him swim or cool him down with water. But what if there is no water nearby or if your dog doesn't like getting wet at all. Or if you simply don't want a dripping, smelling wet dog. Then there is the Cool Dog cooling jacket!
