Marley was in our park yesterday off leash playing (very nicely) with another dog they were running all over the place then this woman came in carrying...yes carrying her two dogs either side of her. Marley naturally being 7 months was curious so went over to see and this woman just went mental shouting at me to put him on a lead, when I got him on we thought best to leave park and woman said please dont let your dog look at my dogs as they are very nervous, after being carried around for god knows how long am not suprised they are nervous, no interactions poor things.
So yes I worry about some people too
