(NSFW) Funny question: How can I make my dog to do this thing? (see detail)

Inspired by this question.

Just for entertainment purpose, what’s the best advice you could give so my dog (assume it’s a male) can do this thing?

I want to see the level of humor of jellies here. Any advice is welcomed!!

PS: You can skip this question if you think it’s too shallow for you or if you consider this as animal cruelty. Thanks!
