I was counting up-the-arse as one (hence the dashes). If you counted them separately your dog would need to know 7 not 6.
Right. Got you now. I don't think I'm alone in thinking that the list you gave was the words the dog knows, from RHC's repetition thereof, and not the entire vocabulary of the Cheese's regulars.
Now that the winds have died down. I would like to thank my neighbours for the garden shed, 2 wheelie bins, an outdoor trampoline, and a 6 month old Yorkshire terrier named Patch.
