i have a small long coat chihuahua that i think may have a few deformities. both of her parents along with her are registered pure blood chihuahuas but she is kinda off looking. she has a scrunched snout kinda like a peke or a pug and her hips are set very low to the ground while her front legs are nice and tall like normal. she also has a very unusually calm shy personality amlost like she was abused or beat. any ideas?
