Rosco is about 8 1/2 months now, and is super excited when he sees people or even my boyfriend and I. He's been jumping like crazy and is knocking even me over! I've tried the air pressure gun, worked for a minute, not so much after that. I try puttin a knee out, doesnt really bother him the slightest bit, still attempts to put two paws up on my kitchen counter. Any ideas as to how I can get him to calm down? Im afraid to answer my own door, or let any guests come in my house, its not that he's scary he just jumps and wants to love you all over! lol. I appreciate the ideas!
