9 month old scared of strangers
Basically over the last couple of months my dog aero has started behaving differently with strangers.
He will now start doing little 'woof' barks and slightly growling. hiding behind me etc. but he still actually wants to say hello to the stranger as he will go close with his body lowered going to sniff them but then gets all silly about it.
I've noticed if that if a stranger approaches him, he is worse but if the person doesn't make an approach aero will go over and start sniffing etc. He has never had a bad experience with anybody before so i'm not sure where this behaviour has come from.
Does anybody have any advice on what I should do when meeting strangers out on walks etc/ or to improve this behaviour in general?
Note: he is quite a submissive dog in general.
