The days are coming to an end for my 13 year old lab. She was my first dog ever, and she's been a great one. I noticed over the last several months her breathing has become more and more labored. X-rays show something in her lungs. I don't want her to suffer but I also don't want to put her down prematurely either. She still gets around decently considering her age, and she still had a great appetite. My question is how will I know it's time?
