The Bernese was a large male, unfixed. I think he weighed about 160ish, stood as tall as I with his paws on my shoulders. His job was guarding the corral area & farm yard from coyotes. Yet he was still gentle with children and other dogs & the farm cats. If I ever have the room I'll get one.
Discussion
Did you notice any differences between fixed and unfixed as well as vaccinated and unvaccinated dogs?
Farm dogs were never fixed. Increased aggression and size, plus the cattle dogs were for breeding too. They were always vaccinated as well to prevent easily transmissible diseases.
Bernese and st Bernards are such nice dogs. I hope you have the room for one soon.
