I have have my sweet foster dog for one week today. When I tell people about her they have very discriminatory comments to share. I even told the vet how snuggly and affectionate she was and she said, "That doesn't sound like a Chihuahua." Most people comment on how yappy she must be, this dog rarely yaps at all. Just three or four barks when someone knocks on the door. I have been told to not even bother to try and train her not to growl at strangers because "all Chihuahua's do that."
So my question is, what are the traits that really are specific to most Chi's that may be just to hard to train away in the short time we will have Jenna? I didn't plan on trying to teach her not to shake (although she rarely does that.). I am focusing on potty training, not growling at people, and the basic commands like sit, stay, and come. Oh also, the "don't climb on the table" command

.
Thanks!
