All good things come to an end, and a dog's life expectancy is perhaps ten to twelve years. When a service dog dies, we request that you please notify us. Personally, it would be also nice if you sent us a picture of where you bury the dog or spread their ashes (that's optional, but really nice). At that point, some families find that their journey with the service dog is now over and they don't need a service dog so much any more, but if you decide you would like us to find and train another one for you, you would then go to the top of our waiting list. So, some families may let us know as the dog is getting sick, or other families let us know if the dog goes unexpectedly, but either way, the process takes perhaps a year because we need to finish up the current dogs we're training (up to six to twelve months), then find and train a dog for you (takes six to twelve months).
