Help I'm at my wits end. Potter has just turned one YO and is a Marley. I have put him through 2 training schools, and I work with him a home. He gets too excited around other people! 2 days ago I took him to the park, he know to stay when I open the car and is good at this command. However he saw a group of people and ran over to them completely ignoring my come command! Went and got him by the collar nearly back at the car and he slips his collar and runs back at them again, by this time I was very unpopular in the park so I took him home. Today I took him out again, get home open the car, he did his stay and was walking to the door when he spotted the young kids across the road, he ignored my "come command" and jumped all over them, knocked one over and scared them all. Any advice as I'm close to giving him up. I have had 4 Golden's but never one like this.
