Dogs are dirty and smell like sh*t... Other than that, they are great companions.
Cats are just there... They don’t care about you and if you die they’ll start eating you. They are way easier to take care of, of they aren’t needy like dogs... So they also make for great companions.
My Shih Tzu goes to the groomer every few weeks and smells better than most people
Chows are like cats in that they have no intrinsic smell and groom incessantly; even after swimming in the river all afternoon, they have no smell.
