this is not a chihuahua. I have both long haired and short haired, and this doesn't match that well.... It is very cute in a way, but its more Papillon than Chihuahua...
Honestly, that makes me feel a little disappointed.. but thank you for your comments. I appreciate any input to help make my drawings better.

So maybe you can tell me what to change?
It may be the head throwing you off a little, am I right? That was the most difficult part for me. I made the ears overly large, but I thought it added cuteness.

However, I have had a pure chihuahua who looked almost exactly like this.
A comparison of the two breeds for myself to look back on:

And yep, a golden retriever is on my list. ^^
