I have recently saved a toy poodle, he has been fixed, he is happy smart not a barker, potty trained for out side, eats well, no table scraps, playful. 4yrs old appricate or white.. he has from what I have learned is wore a little sweater most of his life.. The hair on his back and back of his legs is so thin you can see the outline of his little body which is pink and not dry. just pink and some brown spots. I am so worried. he is very tiny under 3 lbs.
