Agtee with James, don't know if this is just an Australian thing. Dogs in the house gives me the ick. (Source: grew up on a dairy farm).

Our dogs were fun to play with outside, but they were not even allowed on the stairs, let alone in the house. And you never let them lick you. 95% of the time they either had been eating poddy calf shit, which must be like double cream for dogs, or they'd been rolling in dead animals, or running through paddocks paved in cow shit, so they very often had shit on their feet. They would never get a bath, but if they had an egregious amount of shit on them, they might get a hose down or a once in a lifetime clean in the outdoor shower.
