Sorry for your loss. We also lost one of ours on Friday he was an English Pointer named Fred. He was a horseback field trial dog, and had previously won runner up champion in the Georgia Shooting dog championship. Our handler was going to run him in a trial 2 weeks ago and something seemed off about him. So he took him to the vet right away. His lungs seemed to be full of fluid. There is something they call grass all. Its when seeds from some sort of grass get in their lungs and causes and infection. It happens sometimes with dogs that run field trials in dry conditions. That's what we thought we were dealing with. So they drained the fluid though it looked like more in the X-Ray than he managed to get out. Fred was on a course of antibiotics, and no running him the rest of the season. He seemed to be just fine until Friday, when he all of a sudden in a 2 hour period he started to go down hill rather rapidly worse than when he was originally taken in to the vet 2 weeks ago. This was a strong athletic dog only 4 years old! The vet had to put him down, nothing about his lungs and chest looked anywhere near normal in X-Ray or Ultrasound. We are having an autopsy performed to find out for certain what the problem was. The vet is thinking either cancer in his lungs or heart failure now not an infection. We want to alert the people, that have had puppies from him to be particularly watchful of their dogs if this should turn out to have been caused by cancer or heart disease.
It was a pretty terrible day for my wife as this is one of the few things she has to look forward to is her dogs running in field trials. He was performing the best of any dog we have ever had, so she was excited and hoped to see him run in the national championship next year. This dog was just phenomenal!
Anyway - Dogs are our children so this was a blow. I can see how it would be for you as well. We have another that is nearly worn out. He is over 15 years old. He has a real hard time standing up and getting around now. Fortunately we have a couple of young pups, that I hope my wife will get to bring forward.
