Well I'm not paying extra, he'll have to sleep outside, I'll have to go and buy the wood to build a kennel now:P I do have a spare spiked collar though (got at least two, possibly 3, but I've only seen the really heavy, wide one with the double row of steel spikes, and the thin single spiked leather band one around recently. Think there might be one with short metal studs on it somewhere as well.
