Is your darling a hairless or does she have the fine, IG hair? Mine is hairless but they have similar faces.
The twins have very little hair. But their mom has a thick coat.
I actually think they are half hairless, half chi.
Yes, that’s a wide strip of bald on Randy. Lol. He has a bald chest and belly too. I’ve had him since he was a few weeks old, he just has a bald stripe which runs from his neck to the base of his tail. And a bald spot on top of his head. @DotLewis
I have to say, Randy's hair style is unique. Looks like a reverse Mohawk. I've heard through the American Hairless Terrier group I'm in that the genes causing hairlessness in the AHT is different than in the Xolo (Mexican Hairless) and offspring from a breeding between the two (and very possibly other breeds) can have odd patterns of hair growth or baldness. For Randy to have such a defined hairless stripe, there is no doubt some type of hairless in the family. Since you call them "the twins" I assume they were litter-mates. Randy does have a Chi looking head but Dariah sure has the look of an AHT in the face. The pic attached is not my baby, but the face looks a lot like you pup to me.
I've rescued Rat Terriers for 18 years, AHT are an offshoot of the breed so our group also rescues them occasionally. I never really thought I'd find them very appealing, UNTIL I took in one to foster. Much more delightful than I expected. Then later I rescued a pair, same breeder but not siblings. One of them was my little one. Her larger, more sedate "bro" was adopted but Nene had gotten so attached to me and I couldn't send her to a home where she would be alone for 6-8+ hours a day plus I just loved her to death by then so I adopted her myself. Best little hot water bottle ever!!
I do think the Cressies with their little topknots and hairy tail are adorable but I don't know what their personalities are like. The AHT is quite like the Rat Terrier in personality.
