Pretty fantastic bite... much better than Astrid's (her's isn't the best - not totally appalling, but not great!)...
I'll try and get some more photos of him when I'm at home over the weekend, but he has a nicely pronounced stop.
Good temperament as well - not all-over-the-place friendly, but not overly cautious either. Typical good chihuahua temperament.
He's a bit of a sod for lead-walking though! His first show is in a couple of months, so he should be up to scratch by then. I think I would die of mortification if he just sat in the middle of the ring and wouldn't budge, which is what he deems it appropriate to do when we're out walking sometimes
