I'm going through and trying to write off all I legally can. I've got the home office deduction, 25% of my water bill for extra laundry and lawn watering, 30% of treats/food/toys, 25% of phone/internet used for bookings and updates, 50% of gardening work, 50% of flea/tick/heartworm medication, 100% of pet cleaning products & poop bags, a one-time carpet/hardwood floor cleaning for pet stains from customers' dogs (50%) & 33% of our house cleaner costs since most time is spent on dog-related cleaning.

Does that sound legitimate? In addition, I'm wondering if it's legal to write off a percentage (say 33%) of veterinary costs in order to have healthy dogs when people leave their pups with us, no one wants their pet to stay with a sick dog.
