Would i be in the wrong if....?

You are right, golf for a large breed can equal bad news. He could choke on the . I think approaching your neighbor wouldn't get you started off on the wrong foot so long as you do it in a nice fashion. I would just knock on their door and introduce yourself if you haven't already done so. I would then express your appreciation in wanting to give your dog toys to play with, and then I would let them know that you are in the process of training your dog and the toys they are giving him are impacting that. I would most likely leave out that golf are a choking hazard as that would most likely come off wrong. The most important thing is now what you say but how you say it. Best of luck.
