I don't own a dog, but I do have two cats. What's great about the cats is that I don't need to walk them. All I have to do is sift through sand for their poop, which isn't as bad as it sounds. One thing I admire is how loyally dog owners take their dogs on walks. Through hot or cold, rain or snow. I just never understood what you're supposed to do when it was raining. This answers that question.
It's got to be annoying to have to dry your dog off right after going on a walk. Plus, you'd probably want to bath the dog too. I live in Los Angeles. The rain is 50% dirt here. This isn't fun rain. It's more of a "will be acid rain in five years" type of rain.
