I have a big Lab mix named Amy, a Chihuahua/Fox Terrier cross named Barley, and a female Chihuahua named Lil' Chocolate. The majority consensus is Amy looks like Lab/Pit but some see Lab/Rottie-she's your classic big black dog. Lil Chocolate is smooth-coated, black with brindle points, and weighing in at between 4-5 lbs. She's the sweetest Chihuahua you'll ever meet (I'm biased though). Barley is around 20 lbs and light brown/tan colored. I love him but that is a worthless cross of breeds in my opinion. Barley we got as a young puppy, Amy was figured by the vet to be approximately nine months when we got her and the Chihuahua was three years old when we got her. I also have a husband, two precious daughters and four cats.
