Breeder Impressions

[borzoimom]

Actually, you see more undersized agility shelties than oversized ones. As has already been posted, you can get an undersized sheltie pup and an oversized sheltie pup in the same litter. It's the reason being undersized or oversized will lead to dismisal in the show ring. They are trying to get the breed more standardized in size.

However, many agility enthusiasts prefer the smaller sheltie. In AKC, the 12" jump height allows for dogs ranging in height from 10" to 14". Many sheltie agility folks want to jump in the 12: height, and get a pup that they know will be small. The 16" inch jump height allows for dogs ranging in height from 14" to 18".

You asked how big Aslan, my MACH sheltie, is. He's undersized at 12.38". However, my color-headed white, Jericho, is oversized at 16.5". Both had parents that were well within the standard for size.

I don't know any breeders who intentionally breed for large agility shelties, although I could see a demand for small agility shelties. They are very popular.

OH MY STARS!! WELCOME AGILITYK9TRAINER!!!! OH PT'Rs she has the most amazing agility shelties- WELCOME WELCOME!!
That is amazing you see the opposite of smaller shelties verses larger ones. You attend alot more agility trails that I do, and your observation would be more the norm than the my observations would be in this area. Also, the flyball competitions they just broadcasted had some awfully big shelties. Do you find flyball teams using bigger shelties or smaller ones?
