I am a dog groomer. Ninja was given to us as a foster dog who wasn't loved any more at his home. He was about 2 when we fostered him. He never made it past my home. We fell in love with him because he is playful, spunky, naughty (but SOOO cute!) and extra extra loveable. He loves being cuddled, held, and will do anything for a belly rub. He needed some housebreaking, but overall has been such a wonderful pet. His personality is wacky and we love him!
