It was a defect in the base of her spine. When she was between 2-3 yrs old, she started showing signs of a problem. I had her xrayed, afraind of hip dysplasia, but found out otherwise. The vet gave her 2 years, before I would have to put her down. Rimadyl was a new drug back then, and they didn't know how much it would help her. They also said we could try surgery, but didn't have much hope for recovery.
She was 6yrs old when I had to put her down.
It was an incredibly hard decision, one I have had to make a couple times (the last one being the beginning of March, when I had to put my boy, Koda, down, due to cancer).
He was a rescue. He was supposed to be a temp, 4 day foster, but I fell in love and adopted him. I had him for 6 and a half years before I had to say goodbye.
I still miss him every day, but the pain of losing them does not compare to what they bring to your life.
Clearly, your girl is well loved, and she is happy.
Here is an old pic (about 17 years ago) of me and my first GSD.
Then my beloved boy, Koda.
And also my two girls, both GSD mixes. Rory, the black and tan is a GSD/Lab. Alexa, the tan one, is a GSD/Malinois mix.
I've had Rory since she was 12 weeks old. She will be 9yrs old in April. She came from a puppy rescue, who got the whole litter from eastern WA. The mom was a stray, found giving birth to the pups under a construction trailer. Rory was the only one who looked GSD, all the others looked Lab.
Alexa was pulled from a shelter in CA right before being euthanized due to lack of room.
She was brought to WA by one of the GSD rescues. I went to look at her a few weeks after I lost Koda. One of my friends who raises Mal's (she has three) recognized the Mal in her, and had it not been for that friend, I do not know that I could have known how to deal with her. She came with her own set of issues, from her previous owner, but we have worked through a lot, and I wouldn't trade her for anything!
