My Foster Dogs: Meet Gizmo

We have a new foster! Meet Gizmo, who is a year and a half old, weighs about 10 lbs and full of beans. He is a long haired chihuahua and mixed with yorkie we were told, but no one can see the yorkie in him... we just know that he is super cute and looks like he is smiling all the time.
His previous owner was unable to care for him and Gizmo did not get out to meet people, dogs or experience a lot of things that young pups usually do. He is a quick study though and is picking things up fast. He is a great jumper and quick as the wind.
Gizmo still uses his mouth and may not have been taught that this is unacceptable. He does not hurt us and is learning not to do this. He loves toys and will play fetch, but is reluctant to give up the toy when he brings it back.
Gizmo goes for his vetting in a few days and will be neutered and brought up to date on his shots. He should be ready for adoption shortly after that and should find his new home very quickly.
