I definetly see Lab.....not sure exactly what else...possibly hound?
Very pretty though! Those markings on her ears are so gorgeous! Do you have a pic of her back? I can't really see from those pics, but it looks like she may have some more of those markings?
Usually when looking if they have alsation in them, prick there ears to see if theres any real resemberlance...however i dont think theres alsation in her, def lab...and like others had said possibly hound.
No, i say Lab be happy i lost my first home owners insurance because my shepherd X 50 pound mutt with no teeth cost me my insurance .
The Mastiff looking CAS did not. And the mutt would never hurt anyone.
