Great list, can't do Newfs or Berners as my husband's allergies can't handle it.
I have been around Labs for a long time. I do love them but I won't get another one after Petey. I have shown them, worked them in hunt training, and bred them (although I never produced a litter, Petey was a stud dog for a service dogs organization). They are a lot of work and they can have a lot of problems. Very high energy, often too high even for my kids and they shed like a bugger. Don't believe that whole average shedder myth about them. These are heavy shedders. We brush Petey daily when he is blowing coat (which happens 2 to 3 times a year) and we have to sweep twice a day or we have tumbleweeds of hair floating around the house. But they can be great dogs if you enjoy the energy and since you want a Newf and a Berner, the hair probably wouldn't bother you.
My husband can't breathe during two or three weeks of the year. During that time, he always says, "This is it. I hate to do this to him but Petey has to go. I can't breathe and he is going to kill me with his hair." I always nod and say, okay, I'll put an ad up and contact a lab rescue. Then I wait patiently while he gripes for the few weeks. Finally, at the end of the allergy period, he always comes up and says, "Cancel that ad. I could never get rid of my boy."
It is a yearly ritual we have and even Petey knows it. He is usually glued to my husband but during those 2 to 3 weeks, he parks himself by my desk day in and day out until the allergies are gone. I think he knows and feels awful about it. LOL. Daisy's hair and the cat's hair doesn't bother him.
