As a lot of you know, i have 6 dogs. the oldest is the mama dog, and she is about 13. still very agile. the next was the daddy dog trevor, at 12 or 13. a couple of years ago he was diagnosed with heartworms. the treatment is 3 to 400 bucks, and not only does it often fail, sometimes it will kill the dog itself. given his advanced age i did not spend the money. a couple of weeks ago he started losing weight rapidly. down to maybe 70lbs today from 110lbs. last friday i noticed that he was almost blind. by saturday afternoon, he could only see shapes, light, and shadows. for a week now, he still got around the yard well. ran into things occassionally, but still had an appetite for food and water. the last day and a half he has been unable to walk. his range was confined to about a 15 foot area that he could drag himself around in. i took him to the vet this afternoon and had him put down. when i was a young man, i used to put down my dogs myself, when necessary. as you get older, life and its value becomes clearer all the time. the passing of even a pet, at least for me, is heart-rending anymore. i guess i am just a big baby, but i had to put up with teary eyes the whole time. i miss my old dog.
