My big doggie, Scooby, is happy and contented in his back yard. It is about 50 feet by 30 feet or so, and so he can get excited and run hard and fast, and he does sometimes. I brought him in the house a few days ago because I took his fence lose at the corner when I was working on the house wall, and he was surprisingly descent in the house, except when I came in the house, and he got all excited thinking we were going for a walk. He actually escaped from the house, and I was worried for a short time, but he came right back, so I was happy about that! Anyway he has a nice house back there, and he is a cold weather dog, so he is happy to be outside. When we are gone we just make sure he has been fed and has enough water, and he is fine. He dug him a hole, so that he can be cool when it is hot outside.
The other doggie, Rand, we take with us just about everywhere we go, and we leave him at our youngest daughter's house when we need to be gone all day, and he is fine there. She has 2 doggies, a border collie, and a little doggie just like the Royal family in England have. Well, the little doggie bites Rand in the face, playing of course, but Rand does not like it, so he rolls his eyes and growls. He never hurts dogs or humans, so growling is all he does, but he sound vicious. The other doggie goes into the protective mode, and starts barking at him. Then he runs over and sits by his food, so that Rand will not eat it, but Rand will not eat when he is away from home! I'm sure he would if he were gone long enough to get hungry, but for just a day, he will not eat until he gets home!
The other morning our youngest daughter was sleeping, and Wally the Amazon Crown bird flew down off his high home on top the freezer. The border collie went after him. Wally the bird literally ran into our daughter's bedroom yelling help in a man's voice. It tickled our daughter and made us laugh to hear about it, but also we are thankful that nothing bad happened. Our daughter is trying to figure out how to protect Wally so the doggie doesn't harm him while no one is looking.
