You can’t deduct the family pet, but a working guard dog can be a fully deductible business expense.
In Cox v. Commissioner (2005), a taxpayer operated a used-car business located in a high-crime area of Houston.
To protect the commercial inventory and premises from frequent theft and vandalism, he maintained a guard dog on-site.
The taxpayer wrote off the food, veterinary care, and maintenance costs associated with keeping the animal on duty.
Because the animal lived at the commercial site, fulfilled a genuine security role, and was not an everyday family pet, the IRS didn't even contest the deduction.
To survive audit scrutiny, business animals require clear documentation proving an exclusive commercial purpose over personal companionship.
