I have larger 7yr old, supposedly Chihuahua x mini Pincher mix that we adopted from rescue center. Unlike other Chipins - she's got really short legs, so she kinda looks more like a Dachshund. (and about that size too), chewed off ears & tails, with balding back fur that our vets couldn't really figure out why. Definitely wasn't my choice - my daughter loves her. However I'm the one who's taking care of her most of the time, as she sees me as the master, not my daughter.
She's the most timid dog ever - scared of everything and everywhere. Yelps at slight discomfort - I think she has some trauma or sort from pup days... (seeing from that tattered ears and tails) Doesn't like to go out for walk, sits/sleeps in sunshine all day long with loud snore. She's one of the most silly dog out there - with great ability of only hearing/obeying you when she wants to. (She does all kind of tricks when she wants her treats, but not when there's no food involved) - and she is really a great pretender of not understanding what I'm telling her. I've grown attached somewhat, and probably be pretty sad when she's gone.
