Located in NW Panhandle of Florida Please check Spam emails for replies Roo is what we believe could be a Chihuahua pitbull mix. His mom was only 23lbs. He is 4 months old and weighs 11lbs. They say if you double a puppy's weight at 4 months then that should be about what their adult weight should be. He loves to be carried around like a baby. He is so incredibly sweet!
