How I Unwittingly Adopted a Chihuahua

How I Unwittingly Adopted a Chihuahua

Have you ever had a DNA test done on your dog? Have you ever wanted to? When you have a purebred, you don’t think much about it. You have a pretty good idea of your dog’s history, lineage, and evolutionary story. However, when you have a mixed breed dog, you may find yourself asking what his/her story is? What is their history? What behaviors and personality traits are typical for him/her?

After adopting Jax, these questions were a daily thing for me. If you are not familiar with Jax’s adoption story/adventure, check it out HERE. I would study his face and features, watch his behavior and movements (and he has some serious moves!), and note all of his many personality traits. I wondered what lurked underneath it all; what produced the unique creature that was Jax.

One day my husband gave me a dog DNA test for Jax. Apparently, he was sick of hearing my frequent ponderings on the subject 😉 We quickly got our samples and mailed the kit off to Wisdom Panel. Jax sat patiently and let me rub the swabs along his cheek and gum line; like he was invested in this venture as much as I was!


We sent the sample off and patiently awaited the results. Was he a Papillon/ Pomeranian mix, as ResQ Animal Coalition thought, or maybe a Papillon mixed with a fox or rat terrier as we suspected.

Well, we don’t have to ponder anymore! The results are in and to our surprise, Jax is not quite what we expected!

It turns out that those ears are not Papillon ears after all. In fact, there is not a trace of Papillon in him! There is also no trace of Pomeranian in him either.

When I opened the results, I was surprised to read the sentence “Jax is a Chihuahua, Toy Fox Terrier mix”!


I suspected some kind of fox terrier type dog, but I admit, the Chihuahua part caught me by surprise. And that Chihuahua part is 50% ?

Working my way through the results, it made sense.

Recognize any of these Chihuahua behaviors in Jax?

  • Alert, active, and often playful dogs.

  • Small size makes it easy for them to live in smaller places such as apartments.

  • Responds well to reward-based training using treats or favorite toys.

  • May be suspicious of strangers or bark at other dogs when intimidated by their size.

Why yes, I do!

Recognize any of these Fox Terrier (Toy) behaviors in Jax?

  • Agile, energetic, intelligent and playful dogs.

  • Toy Fox Terriers seem to enjoy dog sports such as agility, flyball, and tracking.

  • Toy Fox Terriers learn well with reward-based training using treats or favorite toys.

  • Is an excellent watch dog due to its tendency to bark to defend itself.

Why yes, I do!


I am very glad that those ears are as big as they are and the ResQ Animal Coalition had him listed as a Papillon mix, because otherwise, I would not have come across that special little face during my search.

Regardless of Jax’s ancestry, he remains a special part of our family and we couldn’t imagine not having him and his antics around.
