no dogs or no neighbours

dogs are peeing on our lawn and front door, these are not stray dogs. dog owners do nothing and assume this is normal. with this year snow all over the place, it's becoming easy to see the size of the problem. yellow all around the house. yesterday i watched as the neighbour was walking his dog in front of our house and right in my front door, his dog made the call. the two were gone by the time i got my shoes on. i got out and waited for the couple, and then called in "good morning neighbour!", he noded his head, and i said "can you please don't let your dog pee on our front door again", he said "he didn't", i said "i was just watching you and him from my the window, he did it right here", he said: "it was just a pee", i said: "yes it is, DON'T LET HIM DO THAT HERE AGAIN", the neighbour paused for about 4 seconds, he appear to not like what he just heard, he said "ok" and just kept on going without apologizing or just saying sorry. as he walked away, i called in back at him "THANK YOU .. NEIGHBOUR!"
