We then had her spayed on December 20th. Following the surgery, she never fully got her appetite back. She had spurts of her old self but overall never fully recovered. She had previously been full of energy and joy, always eager to play with us and strangers.
We took her to the vet. First, she thought her lack of appetite was due to the surgery. Then Teka got a lot worse. The next time we brought her to the vet (a few days later), she was surprised how much Teka had taken a turn for the worse. She gave Teka steroids, antibiotics, and an IV. She also did a blood test and it was discovered that Teka had a very high level of calcium, which could either mean cancer or vitamin D poisoning. We did notice a lump near her throat/ear.
Two days later, I brought Teka to be put to sleep. She had not recovered at all. The vet did say we could bring her to Appleton to a pet hospital, but she was not hopeful that Teka would be able to fully recover. It was a tough and heartbreaking decision to put her down. She was the first dog that I had ever had. We miss her. My memories of her will be watching her run so fast and free around our house in every season, surrounded by the Northwoods. She was such a gentle and fun dog for our family. I put together a compilation video of Teka moments:
