Hi, lol. If you find the answer to this question please let me know. I have two EB siblings, my female Blossom will walk for hours, she has so much energy, but her brother Bulldozer does the same thing Sherman does. He doesn't like to walk, he gets outside the house and will do his duties, and then pulls to go back to the house. If I try to take him for a walk, he will walk for about 5 or 10 minutes, and then will lay down and refuse to move. I feel bad sometimes, because I will go on long walks in the morning or evening, or on a cooler day with Blossom, but I leave Dozer at home because he won't walk. One time my son and I tried to walk up to the plaza by my street, to go to Tim Horten's' and we got there, but he refused and just wouldn't walk home, he weighs 45 lbs and I can't carry him home, so we had to call my hubby and ask him to bring the car to come and get us. Lol. He is happiest sleeping, or cuddling with us.
