I have a teacup poodle of about 15 years now. Last summer, her eyes developed cataracts and she usually is blind. Sometimes the swelling is down and she sees but she is usually blind. She's considerably deaf too. I can get by with walking on a broken floor right past her without her waking up or interrupting her itching. Our poor little dog does fine sleeping when we aren't home but tends to act nervous and scared when we are there. She'll cry for us to come but just itches when we come. I'm leaning towards believing my dog is just suffering and there really isnt anything that can be done. Is it time to let her go?
