I'm very sorry to hear about your injury. I hope you can recover quickly 'cos I know how aggravating it is to be immobile.
I agree about the sensitivity and good judgement of this breed. When Scout and Gypsy were only about 8 months old and still in the chase each other around and bang into walls phase, we had to go visit my Mom (who is in her 80's and walks with a cane).
I'd prepared myself for the idea that they'd have to spend 2 days in her backyard because I expected the normal puppy foolishness to make having them inside a chancy thing. From the moment we arrived though, their whole demeanor changed. They were quiet, didn't jump on anyone the whole weekend. They just walked up and put heads in her lap to get petted then laid down under the breakfast room table. Like someone had traded me for a whole new set of Pyrs for the weekend.
I've discovered that they're gentle around all older people we've met on our patrols. No jumping, just cuddling standing up. Not sure how Pyrs manage to be so intuitive, but then I guess it's because they're not really dogs after all.
