Meet Jax, my Adopt A Pet Of The Week! Jax is my first ever Yorkie mix on Pet Of The Week, and he is SO friendly! This 3 year old yorkie yorkshire terrier mix was an owner surrender through no fault of his own. You can see more pictures of Jax below, and I might see him at the OSCAR 5K this Saturday at Skylands Stadium. Find out how you can join me by clicking here.
