It seems crazy that anybody could not be a dog person.
Dogs are humanity's best friends and have been for over 2,000 years. The little waggly tail pup that you have coming up to you and licking your face after a long day is one of the most therapeutic feelings in the world.
But some people just are not dog people. Maybe they're cat people. Or maybe something bad happened with a dog wen they were younger. But non-dog people exist.
