Does anyone keep their mastiff outside?! I adopted my big man 3 years ago and have kept him in a outside pen since, which is on concrete with a roof and fan and all! He loves the outdoors and much of the time when he is inside (extreme heat/extreme cold days) he sits at the door and whines to go back out. I know people say its terrible to keep them outside but he doesnt seem to mind. He is walked every morning and then as soon as i get home from work, i immediately take him out again for about 2 hours. Just wondering peoples outlook on this bc having him outside is not the worst thing. Also, the boyfriend and i differ on how i think he should be taken care of. If it was up to me i would def keep him in, but he doesn't think that its necessary. He says that he sheds alot and is scared that he will have an accident while we are at work. He is house trained though. =( but all in all he lives a happy life!
