I was shaving Mr. Biggles some more last night (doing a little at a time not to over stress him... only have his legs left to do now) & when I was doing his chin, I opened his mouth to take a peak at his teeth. The bugger has 4 K9s on his upper jaw The extra ones are infront of the normal K9s & they are a bit smaller, but still pretty darn big!!! His lower K9s fit right inbetween the top ones (he has an under bite)... Silly thing
