You cant be too careful , I have had a couple of incidents where dogs have tried to pick up my little Lottie as she is now terrified of other dogs, she will try to nip at them and run so I dont let her approach any dogs we dont know. She has some little yorkie friends here whom she adores but anything bigger than her or not a yorkie and she hates them!!
As for that comment that woman made ,,how rude!!!

i'm embarassed for some people!! They dont even seem to notice ho rude they are.
