Seriously? At least 90% of dog owners do NOT clean up after their hairy turds and when a dog-owner puts a house on the market, the grass in fenced yards is so patchy and destroyed, realtors advise the owner to plant grass before the house is advertised. Even if dog shit is picked up, it still leaves toxic residue that kills grass and pollutes the soil. Additionally, after being covered by years of dog shit, the soil is so polluted that new grass want even grow.
Indoor dogs aren't worth 2 hoots in hell if your house gets broken into. A TV station in Oklahoma installed hidden cameras in dog owners' houses and had an "intruder" wearing protective padding enter the house both when the owner was, and wasn't there. If the owner wasn't there, the killer dogs (even Rottweilers and pit bulls) ran to another room and hid from the intruder. If the owner was at home, the vermin (dogs are vile vermin) hid behind the owner expecting the owner to protect them. A woman who bought a Rottweiler for protection was out walking her overgrown shit-machine one night when she was attacked and raped -- the big, bad Rottie ran away!
Dogs are filthy. They stick their noses in other dogs' asses, eat human shit, eat their own shit, then vomit it up and lick up the vomit, and wallow on carcasses of dead animals. Anyone who touches such a filthy, disgusting POS is as filthy as the freaking dog!
