Our dog is 5 months old, she is well socialised & has been regularly exposed to lots of things in a possitive manner all of which she takes in her stride & enjoys life to the maximum. Thunder storms, loud noises, crowds, traffic, horses, fireworks, the washing machine, electric groomer clippers & outdoor jet spray washer do not phase her at all however the one thing she does fear is the hoover. She has never been given reason to fear it but because we have predominantly wooden flooring the hoover is not in everyday use & as soon as it even looks like someoone is about to use the hoover she becomes wary & tries to hide away from it. We try to ignore it & dont make a fuss of her or a big deal about it but want to try & overcome this while she is still young without making it worse. Any tips would be appreciated.
