Jojo started to swell in her abdomen and get skinnier everywhere else. She was quite old and couldn't run and chase after rabbits or go up or downstairs anymore. The vet said that she had a tumor in her stomach, and it ruptured and she was suffering. We were able to say goodbye to her before she was put down.
I have to admit, sometimes I was annoyed by her, she wasn't house-trained and shed like crazy, but she was a constant in the lives of our kids. They couldn't remember not having her. She provided protection for our family and was a great running companion. She was someone to go to when you needed to cry, she sat and loved you (and licked your tears). She was loyal to the end.
