I'm just such a passive person and very quiet that before on two instances (months ago) a stranger asked to pet my dog and I let them when I shouldn't of and I knew better but I couldn't bring myself to say no (normally I just try and avoid all people and not pay them any attention, but these people came up to me regardless). So after that, for the sake of my puppy, I said I would never allow it again. So I think my friends (being that I know them) it was easier for me to perk up and say no.
I've done enough research and understand why I shouldn't let them pet him, but they just made me feel like I was being mean to Finn... Which I know I wasn't. But yeah, as Chip said I have a people problem and I do need to toughen up! lol which I will set as a personal goal for myself to have some thicker skin.
Finn is definitely a people lover.. loves to be loved on.. so I can see it hard for my friends to ignore him. My older one was more weary of strangers when she was younger and took much longer to warm up to new people (not an issue now) so they understood with her. Now they just think I'm depriving him of being a carefree happy puppy...
Julian, I have not tried the prong on him I did work with one with my older and helped a lot. The trainer I currently see has us using an ecollar... Which after going to training for about two months now he's been doing great! Made lots of steps forward. He does excellent in his group class. Just the normal puppy excitement that I deal with here and there which is expected from an almost 7 month old.
Chip, I have read your link (few months back) on the Sit on the Dog, and I did use it last night at my parents and it helped! Took him a bit but he laid down quietly at my feet and finally just took a nap! Even with a bunch of people and two small dogs barking at him. I'll be sure to implement it more along side his place command
