He is very huggable! His only downfall is that he sheds like CRAZY and he gets really hot really easily (and he drools like nothing I've ever seen) - he likes to sit on your lap but won't for more than 20 minutes because he overheats. In the summer he just sits in this wading pool we bought him. He absolutely loves people, but the thing I love about him is that he's a great guard dog but is good with people we want him to be good with - the breed can read body language of their handlers and so gets agitated when their handler does... when we have company and we're happy, he's happy. When we don't like the people he's very anxious. They're also very family protective - when I went away to Europe for a few weeks in '08 my parents said he moped. Dunno what he's going to do in a year when I go to university...
They get along really well together, mostly because they can play rough with each other which they both love - I like to wrestle with them but they can get really carried away and Bear is the same weight as I am.. it can get dangerous and overwhelming when they get really playful!
I hate that big dogs have such short lifespans... the average lifespan of a Pyr is like 9-10 years.
I wouldn't worry too much about the puppy harassing your older dog - if anything it helps the younger dog become more socialized and balanced and your older dog will tell the pup to get lost if he's being annoyed.
