It's because they are so often bought as status dogs...goodness knows why because yes, they are gorgeous.
I reckon so long as you're not wearing a hoody you'll be reet
Seriously though, I know from experience that taking on a rescue dog is no small responsibility at all and so hats off to you. It has been four and a half years since I got Hollie and she has gone from wanting to kill any dog she sees to living with three others. She still gets anxious around other dogs if they are too boisterous, but now she just runs off and gets out of their way.
I think bringing another dog into the home is a fab idea...but beware, rescue dogs can hang onto some weird and not noticable anxieties and behaviours that can be easily taught to pups, so I would very much advise puppy classes or, as Stretch and me did...socialise like mad so that you take away the chance of unwanted behaviours setting in.
As for other people crossing the road though, ignore them. We get the opposite, people see our four and just want to barge in and say hello...which is not good when trying to teach one of them that humans aren't scary!
Love the pics, they are both adorable
