Too cute! Is the girl in the back a mix? I haven't seen quite that coloring before.

No she is a full long hair chihuahua.  Her color is called "blue."  She looks black, but if you look at her closely you can see she's actually more of a blue/grey than straight black.   She also has a bit of pigment loss on her nose, which is normal in blues.  It's some kind of mutation that I don't recall the specifics of.  

She has some alopecia on her ears, which is one of the issues that blues can have.   You can't breed two blues together and expect good results due to it being a mutation.  Her blue fur is also a different texture than the white.  It's almost like how a bunny feels.  It's very soft/cottony.

All three girls are full sisters.  They are just from different litters.  We loved Teq so much that I wanted one more puppy from the same parents and then when I decided I needed one more chihuahua her parents had just had a litter, so even though it was about a year earlier than I planned on adding a new addition, I could not let that pass by    They are 5, 3 and 2.

Awwwwww cuties!!!!

Also, and I'm blaming @Fascinated for this because of her spermy drawing, but when I read the title of this blog post, I thought it was about Curious' "girls"  (is it worse that I thought this, or that I thought this and still clicked lol)

They're all very cute!

Odd place to put it, but @Curious when I try to go to your markers blog entry I get Error code: 2B202/1

So do I. 

I unpublished that post because I wasn't finished with it.  I accidentally set the date wrong so it published a day early and unfinished.  I'm going to finish it right now and will republish it.

Sorry for the inconvenience
