Not everyone is able to access a river, or provide a kiddie pool full of water in a garden. However, your dogs still need entertainment and exercise, otherwise they will become bored and despondent. We are lucky enough to be around ten minutes walk away from a river, which our two play in. We still don't take them down there until it's out of the hottest period of the day, because the heat from the ground, and direct sunlight, isn't so much fun for a dog with bare pads, and a fur coat. There is some contention surrounding feeding ice to your dog during summer, to keep them cool. Some people believe it causes bloat, some people believe it's harmless. A bucket filled with water and toys/treats, and then frozen, is supposedly a good way to entertain a dog in the hotter weather. I haven't done it, and I'm not sure about its safety, so I need to do more research on that first. How do you entertain your dogs when it's too hot?
