I own a Beagle-mix and she hates the warm weather. I love to excercise with her though and I like long, endurance type excercising whether I'm walking, hiking, or running.
I will be making another four-legged addition to my home after I finish college next spring. Which breed of those listed below would be okay going for long walks/runs in 20 degree Fahrenheit weather, but also 85 degree F weather?
Newfoundland
Great Pyrenees
Rottweiler
German Shepherd
Mastiff breeds
Saint Bernard
(I am looking for a 100+ lb. breed from the shelter, so most likely mixed with a couple breeds)
