Want a Dog?

Went for a walk today with a friend of mine and, it was sad. A dog came out of his yard and followed us. It was a large dog, we've seen it before and it has followed us before. Today, even though it was limping, it still followed us. It seemd glad to see us. But we didnt want her to follow us across the main road, we didn't want her to get hit by a car. We tried to get the owner but no one answered the door. Later on our way back someone was home. The amn put a rope around the dog's neck and she didn't want to go with him, she wanted to stay with us. It broke our hearts. The man said he didn't have time for the dog. He asked us if we wanted it.
I have two dogs already- I couldn't possibly- but I felt so badly for this poor dog- when she was out walking with us she had a spring in her step and she was wagging her tail, sniffing about and exploring the neighborhood, greeting strangers.... we had to keep explaining that is wasn't our dog!
It's so sad that someone would get a dog, and not give it the attention it needs. Dogs are social animals, this poor thing just wanted to be petted, a little attention-she could see I was a "dog person" and I think that's why she wanted to follow me.
it was so sad.
Anyone want a dog?
