"Come on, it's wet out here"

Well, that's what you get for being a dog, cats can do it indoors because they use a litter, dogs have to go outside.
Mind you, it's one reason we have dogs rather than cats, litters can be smelly even if you do clean them regularly!!
Having said that we are having a guest from Sunday for a few days, Charlie is coming to stay with us while our Daughter and future Son-in-Law go on holiday to Malta.

Charlie is no trouble - but there is the litter to deal with of course.
