What Breed is My Dog?This is Trooper, I rescued him from a shelter about a year and a half ago. He will be turning 2 in April. They told me he is a Chihuahua terrier mix, but he's 35 pounds and insanely muscular and toned. A little bigger than a Chi! ;D He is extremely loyal and obedient. He's all white with 2 brown spots on his back, the brown mask, and a brown little butt, and lots of freckles.
