I've got two accounts that have dogs. I charge them $10 extra, carry a 10' garden hose in the truck, if there is not one on the customers property I can use. Plus they give me plenty of extra work through out the year. I quickly hose my boots, the mower rear tires and a quick squirt under the deck if the smell is bad. Then I'm on my way in 5 minutes, no big deal. I grew up shoveling **** in a dairy barn and slopping hogs, I'm used to smelly boots. Husky liners are a must for the truck.
