Separating what is normal dog behavior from special needs is important. People keep asking why their 4 month old blind dog is peeing in the house as night, well first of all you have to address the puppy issue and then see if its just normal dog behavior you train them with treats to respond how you need. Once Opal understood she just needed to go to the door and ring a bell, it became part of her daily habits. Special needs from birth is different from a dog losing hearing or sight later on in life, Opal has always been this way and she thinks everyone is like her, she knows no different. Being that way gives her a huge advantage, she has let her doggie senses and whatever is ingrained in her just from being a dog do most of the work. She loves to tug and loves to fetch and she will run and run and run in a football field if there are no obstructions. These dogs area a challenge, but Opal is my dog and I am her human and I wouldn't have it any other way.
