i know mine that look like his are kenyi. i got both mine at same time and was all from same fry litter . heres pic of mine when i got them and the picture up there on the post is of the blue one a few months later.
well the only reason i guessed yellow lab x is because it has the the tracings of a black dart on the top fin like mostly all yellow labs do. i know not ALL yellow labs have that black line (i have a pale yellow one that doesnt) but it just looks so much like a lab. then again it could be a kenyi mix too..
