<human>: I love my boyfriend's mother to pieces, she babysat me growing up and I've known her for 20+ years. She is a great lady, so please don't think she's a terrible person just because she's got seriously wrong ideas about dog training. We live next door to her and the dogs she has raised are well-adjusted, good dogs (which makes it more difficult to approach this subject). She's also offered to watch our new puppy some days when we are away at work, which is wonderful because he won't have to be alone all five days of the workweek.

However, she's old-school, has watched too much Ceasar Millan, and the first time she met our puppy she put a choke chain on him and tried to drag him around for a minute (thank the gods it was literally only a minute because I was outwardly speechless and inwardly losing my shit), and she's already told us that "the best way to housebreak them is to give them a good whack and rub their nose really good in it," which also greatly concerns me. I don't want our little guy to associate leashes with bad things, we plan to take him out in public for walk/hiking on a leash a lot! I've never trained a dog before, but I know I'd much rather train one with positive reinforcement rather than having my poor little guy fear me. Plus I love dog kisses and I don't want my boyfriend getting his face rubbed in shit before he nuzzles me so why would I want to do that to my dog?

I really do love my boyfriend's mother. I love that she wants to play with our puppy during the day so he doesn't have to be cooped up in the house with nobody to socialize with all day, but I definitely don't want him being subjected to choke chains and shit in his face either!

Could you distill the essence of the text into 1-3 sentences?
<bot>: How do I tactfully inform my pretty much mother-in-law that I don't want her employing her own methods of training on our dog?
