misha is scared of the muzzle. last time the man was carrying the muzzle like people carry masks sometimes. just in case they see some covidian molecules heading for their face, or in case the dog should of all times be aggressive this one. anyway the mask was on and the muzzle too and everyone was lovely. i said, you had another dog last time i saw you right? (this one is five) and my brain said, yeah and that one bit barney. so i have noticed, not to typecast mind you, because i don't see how it works or with who, but something is being transmitted to the dogs of certain people that makes them (and me) nervous. 
like people they are not born haters, they are triggered in some overt covert way.
