Some symptoms that indicate a dog is near death include incontinence, dulling eyes, sadness, or when the dog seeks a quiet place or barely moves. Dogs go through various stages during their last moments; thus, identifying these symptoms is important in getting prepared for a pet's death.
During his last moments, a dog tends to seek a quiet place away from people and other pets. Also watch for the dog to show sadness and no longer get enjoyment from things he once loved doing. A dog that does not urinate or defecate in his usual place may be a sign of coming death. Increasing infections, such as skin problems and eye discharge, is also another symptom of a dying dog.
