Loki

Bio

Meet Loki. He’s supposedly a Jack Russell terrier and Labrador mix. He’s a middle sized guy, weighing 38 pounds, very slim waist, deep chest and he’s also very slim, but muscular.
I see the Jack Russell in him, but have doubts about the lab mix. He’s very thin, and his structure resembles more Gray Hound or Whippet to us than a Labrador.
Any suggestions? Thanks!
