Right to the end, she was still happy and bright and brave, still wanting to play, however I made the decision to put her down as she was losing too much weight from the constant pain in her shoulder (vet suspected bone cancer however xray scans only showed slight shadows) and could only walk about on 3 legs. Her condition was deteriorating fast and I knew it wouldn't be long before I had to make the painful decision. She had numerous trips to the vets for blood tests, muscle and bone manipulation and xrays to try to find the exact cause of the shoulder pain, was put on cortisone, which didn't work, then on metacam which only eased her pain temporarily.
Roxy passed away peacefully in my arms at the vet surgery, 2 weeks before what would have been her 12th birthday.
I brought her home with me and buried her at the front of the house, with stone angels standing guard over her grave.
