LS, when we adopted her after she came from Puerto Rico she was supposed to be a 75 lb lab mix (we got her at 6 weeks old). Um, okay, maybe not.
She is just over 30 lbs, but she definitely has lab in her! She has webbed toes!
The vet says he sees Chi, pug, beagle, lab, Shepard, and a few more. She really is a Heinz 57. He said she truly had two Puerto Rican mutts as parents.
