@yingtai I had an aunt with a racist dog, due to the dog being terrified by a black guy as a puppy. They could never really get this trained out of the dog.

I hope people take this seriously and help with this.

@yingtai

Just clicker the dogs to be friendly to strangers and enjoy being petted. No need to make distinction in unfamiliar actitudes.
(tried , tested and aproved)

Well, you might save those efforts about "signs of fear or confusion when encountering unfamiliar physical attributes" for the owners, in particular from the right spectrum, that might give some results ..

@yingtai You mean if I were in the UK, I could tell people that I'm growing my beard due to requirements for guide dog training?
And then go and be around guide dogs for a good cause?

That'd be a proper win-win scenario.
Is that a thing in Germany, too? 🤔
