Hi there, my name is Amber and I recently lost my beloved Weim named Marz in August. My dream dog has always been an English Mastiff and though I've read all there is to read about them, I thought I would ask experienced owners a couple of questions that I've been wondering. The breed, the health, the size and everything that goes with a large breed dog I'm up for (Marz was a big Weim at 114 lbs, no where near the size of a Mastiff but Marz was not a small guy). I like to take my dog everywhere I go and I mean everywhere; road trips, we have a place on the River in Arizona, car rides from CA to Utah to see my mom, bbq's/get togethers at friends houses and even to work. How well do they travel? Is my Toyota RAV 4 too small? Do they do well in the heat? Is it easy for them to get in and out of a car?LOL! I want to make a wise decision and I want the puppy that I get to be happy in the environment I bring him home to and just because I've always longed for a Mastiff does not mean that a Mastiff would do well in my lifestyle. These may be werid questions for some but any answers are greatly appreicated!
