Rocco's mom was a Rottie and his tongue hangs out a lot.
LOL! Perhaps these too-big tongues are haphazardly created through eugenics...Bre
eders want rottweilers to have big, square heads (unlike Betti's little bubble-head), but try to produce lines with shorter, broader snouts. Somehow I don't think the breeders are exactly genetic engineering experts and do not account for the tongue, which ends up thick and stocky, just like they are hoping will happen with the rest of the dog...
Even funnier, sometimes I think it ends up that the only big muscle on the rottie's body is a big, sloppy, floppy tongue which acts as a convenient, moist toilette, washing him-/herself.
