To add to this, starting with 'can you not' is automatically framing it to people who are bothered by this as a negative interaction because the starting premise is negative ('don't do the thing').
If you reframe it in the opposite way ('do the thing') with a 'please' to soften it a bit you'll probably have more luck, eg:
'Please can we keep the dogs untangled?' ('We' also helps here because you're assuming some of the responsibility for keeping the dogs untangled rather than it sounding like you're pointing a finger of blame which will get people's backs up pretty quickly)
Not autistic but worked in complaint management for a long time and learned how to more effectively get people on side. Also have ADHD and speak without thinking a lot and it helps to understand why whatever I just blurted out annoyed someone!
