Had to put my pup down a little over a year ago due to cancer... Sucks, plain and simple.

Came home from a business trip and she had a huge swollen eye... Thought maybe a bee sting, tried drugs and it got better for a bit, then much worse. They wanted to remove her eye, but couldn't offer any sort of opinion whether or not it would fix the problem. I sought out other opinions, but came back to the same conclusion. 11 years isn't abnormal for a lab. I've seen anywhere from 9-15. Still hurts.

Sorry to hear.
