Very Sad

Last night I came home after having a great time w/Ong celebrating her birthday to find out that my parents had to put one of my dogs to sleep. She had been having trouble standing up on her back legs. They did a series of tests and even tested for cancer, but it all came back negative and she started to get better, but I guess the last few days she seemed to be in more pain than before. The vet said that it probably was cancer and a week ago when they did the first cancer test she mentioned that it wouldn't be 100% accurate and that we'd have to do a bone marrow test to see if it was cancer. So, yesterday the vet asked if my parents wanted to go ahead and do the bone marrow test. She said it would take 2 weeks to get back, so in the meantime our dog would be in pain and since the vet was pretty sure it was cancer, my parents had her put to sleep. :( It just really sucks. She was seriously the sweetest dog. She was a pure white Australian Shepherd and because of that her eye sight wasn't as good as other dogs and she was deaf. (Something genetic w/white Australian Shepherds). It's sad because my dad rescued her from his work 4-5 years ago. She was roaming around and his boss would usually call people to come shoot stray dogs, but he saved her and brought her home. I just hope she had a good life with us...and though I am sad, at least she isn't in pain anymore.
