This litter over all tested submissive to people. I've never tested a litter of chihuahua's but perhaps that's why they are so snappy (in general). Spoo, my girl was dog and people submissive, and with slow steady socializing she has enough positive experiences in her memory bank she is now high functioning, but.... it's always there.
This litter arrived today! Mom is a tiny mix, perhaps some Chihuahua in her? Dad is a mix as well, the general thought is he looks lab-ish
