Would really appreciate some advice on how to deal with a 1 year old who has suddenly started reacting to being petted.
By way of background, have had her since 8 weeks old and everyday she gets walked in the city centre and must be approached by between 10 - 15 people a day. She is fine at the park and at the beach but is generally off lead then. Recently when in town, she has started backing away, tail wagging when stranger men (only men never anyone else) reach out their hands. If they persist even just leaving their hand for her to sniff, she has been known to airsnap. I've tried repeatedly telling them not to approach her but they don't listen and I really don't want this to escalate. Timidity can run in her breed but this is just showing up for the first time and only with some men.
Have tried teaching her to bump her nose with outstretched hands ( works with everyone but the scary men) have tried having treats passed to her by men she's scared of but she's getting worse. Really don't want to resort to muzzling if I can avoid it but nor do I want this to escalate. She's a very striking dog and people seem unable to ignore her and not approach her.
Would welcome any ideas - thanks
