Definitely a chihuahua mix. Its got chi eyes and ears the whole expression looks like chi chi and who knows the other half or it could be just a run of the mill chihuahua.Look at that ugly taco bell dog.It is a Cute pup and chi's come in that color and those markings. But the eyes give it away that and the shape of the head. its a cutie. Lucky pup it got found by someone who cares.
Ugly Taco Bell dog... LOL One look at those eyes and that smirk, definetely Chi in the lines. Has to be at least 1/2. But I do agree, I see Beagle or something else thrown in.
