This is probably a good idea. How old is Sam? Like you I was quite surprised that a golden would ever even growl...they obviously love their toys
Good Luck..I'm sure it will be ok.
He is a year old... He's been doing really awesome at home lately so I have hope(as far as the resource guarding goes). My husband normally has him during the day but I've taken over with him and work in lots of obedience training during that time(I'm a housewife). I think I really have to stay on top of things with him... I don't want to use the word "dominant" but he is VERY head strong and if you give him am inch he will take a mile.
Kyleigh suggested I practice doing some obedience work with Sam and Ollie in the same room(they would both be a ways apart from each other and tethered so either one couldn't interfere) so that Sammy could hopefully see that I am the leader and in control with Ollie as well.
He obeys my commands very well, its just when it comes to other dogs is where I'm having problems. He is absolutely stellar with people though, I think he would make an outstanding therapy dog! We can't go anywhere with him without being stopped and him making even grown men fawn all over him and baby talk, lol. He is also so good with small children, I mean he absolutely adores them that it makes me feel guilty that my husband and I don't plan on having any.
He has his good points, I just have to remember that when he's making my hair turn grey.
I have also been paying a lot closer attention to his body language trying to figure out all his cues, I know one is going rigid but hopefully I'll be able to figure out more and be able to stop him before something happens from now on.
