There is no definitive answer to this question as it largely depends on the individual dog and its comfort level. Some dogs may be able to live a few more years with continued treatment, while others may be ready to go after only a short period of time. Ultimately, it is up to the pet parents and their veterinarian to decide when it’s the right time to put their dog to sleep.
If your dog is showing signs of decline, such as difficulty eating or moving around, it might be time to give him or her a gentle medical retirement. However, if your dog appears to be doing well and is only showing minor symptoms, there may not be any need for formal euthanasia at this stage. It is important to speak with a veterinarian about your specific dog and his or her health in order to make an informed decision about when it’s the right time to put him or her to sleep.
