Jasper is 20 weeks old now, so 5 months(ish). He does ask to go out for a wee most of the time, and is always given a small treat for performing outdoors. Indoor messes are just cleaned up without comment. So far, so good, right? Except sometimes he will ask to go out, run around a bit, do bugger all and come back in. And then will piss spectacularly on the floor. Tonight he christened my rug. He has crossed A Line. So, how do I get him to only go outside, and stop randomly peeing by the back door or on my rug when he has just been let out? If it helps, he's 3/4 cocker/1/4 springer.
