My four legged family is definitely my best friends, every one of them individually, and as a whole!
I especially find my middle size girl my partner. She was the first dog I ever had by myself. We lived in an apt. in the city. We quickly bonded and did things together. Prior to living in the city, I had lived in the country where when you get 'tired' of having a dog in the house, you simply have them go outside for awhile. Since I didn't have that luxury in an apt, I adapted.
We were both alone, she was a shelter pup. It was an awesome way we came to find each other. I had seen her in the section where you are not suppose to go, in the section where they are not 'pulled' out for the general public yet. That was one trip. When I went back, it was closing time and someone asked me what I was interested in. I told them, and when they looked her up, the lady gasped. This pup was overdue for being killed. I said instantly, QUICK, tell them someone wants her and don't let it happen!
So I went through all the normal adaption procedure. This dog knew, she knew, I had 'saved' her. For the photo they take as you get your dog home after their surgery, she leaned against me and they said, look, she knows her momma already. I often wish I had a copy of that picture.
Anyway, as I said, we were both alone, and I took her with me almost everywhere. She grew up in one of the local dog parks. She was truly a blessing to me. We are family. She was and is the best partner I have ever had.
