I think dogs know it too. Mama Dog was a stray that wondered up to my parents house. I was the one that always took care of her, even though she was suppose to be my sister's dog. But she has that really loving, cuddly personality about her, as if she knows what would have happened if I hadn't taken her in. And Missie, she didn't even know she was a dog until she came here. Sure, she had a nice yard to live in, but she was alone and neglected. Her owners would forget to give her water, and in July in the south, that is not very good. When we went to get her, we didn't even see a house or any shelter for her. Here, she has the choice of two dog houses, or the porch. For water, we have a big metal bucket, a smaller plastic bucket, and a swimming pool (just a kiddie pool for the dogs to cool off in) for her to choose from. And the look of love she gives us. She knows that she has a real home now. I really believe that the dogs know.
