The dog
 

My neighbor found out her dog could hardly hear so she took it to the veterinarian.
He found that the problem was hair in its ears. He cleaned both ears and the dog could hear fine.
The vet then proceeded to tell the lady that if she wanted to keep this from recurring she should go to the store and get some "Nair" hair remover and rub it in the dog's ears once a month.
The lady goes to the drug store and gets some Nair" hair remover. At the register the pharmacist tells her, "If you're going to use this under your arms, don't use deodorant for a few days." The lady says,
"I'm not using it under my arms."
The pharmacist says, "Well if you're using it on your legs, don't shave for a couple of days."
The lady says, "I'm not using it on my legs either. If you must know, I'm using it on my schnauzer."
The pharmacist says, "Stay off your bicycle for a week."
