I have jack russells who do the prominent terrier hop when happy, ie on a walk, i wondered if parson russell terriers did this aswell? In fact do all terriers do this? Which and which don't?
Thank you x
A: All terriers don't do this. This is indeed a health issue called a Luxtating Patella. It's where the kneecap pops in an out. Depending on how bad it is, sometimes surgery is urgent to repair it.

They can have other spots, but it's most average for them not to. It just happened that none with spots made it to that part of the judging.

kick the bucket your standard, but I'm fairly certain it's a bit like the great danes. 99.9% of the measure, it's a brindle or a fawn in the ring-but blacks, blues, mantles and harlequins are just as delightful.
