It's not just you.

I have 2 greyhounds and people grab their kids and cross over the road with there dogs rather than walk past us. I can walk 5 whippets together and people are not bothered but if they see me with the greyhounds its totally different. Most of the people that cross the road have yorkies or JRT .

I now just ignore them and carry on walking. I know that my dogs are friendly and great with other dogs although they never run free with other dogs as they are too rowdy and big. You shouldn't have to justify why you own that particular breed but I think it is staffies that are called nanny dogs because they are so good with kids.
