Lost our little Mini Poodle two weeks ago, just shy of his 13th bday. Started having trouble breathing, trip to the vet showed his lungs were full of fluid. Treated with medication and seemed to recover, hoped for 6 months to a year, however a week later it was back. The medicine would destroy his kidneys so at 2 in the morning, we took to the all night animal hospital where the vet revealed that his lungs were full again. Had him put to rest right then, will miss him, sweet little dog we had since he was two months old.
