I say Max is mostly chihuahua because that's his most obvious feature, but he's got some terrier in him too that I'm sure of, possibly Jack Russell. Max showed up with no collar at my friends warehouse in an industrial park in the middle of a slush storm. We don't know where he came from because there's no houses in the immediate area, and nobody knows how he survived long enough to get there considering the freezing temperatures over the distance he must have walked. After a couple weeks of flyering local businesses and shelters, I decided to take him in myself. He was malnourished and skittish, obviously having come from a rough environment. Today, two years later, he's put on some weight and has a happy, healthy life!
