Honor,
My ex has 3 dogs. One was left to him after his father died and that one became my dog when we were together. I have loads of pictures of him and miss him. I used to send the dog care packages when I was away at school.
Anyway, ex of course kept the dog despite telling me throughout our relationship that the dog was mine. I got a new puppy 6 weeks ago. I LOVE him. I do miss the other dog, but I know that dog is happy with the other 2, and Marvin (new puppy) and I are very much in love.
