These neighbors have indoor dogs who come outside through their doggy door, several times a day. If we are in the house and hear them bark, Jax stops whatever he is doing, looks at me intently and reaches toward the outside window. I tell him, "Dog!" and he laughs. Then we go outside so he can stick his hands through the fence and let the dogs lick his fingers. Such delight.
Here he is clapping his hands which means he is happy. "Happy, happy, happy!" we say when he claps his hands. My joyful son.
