The little one doesn't even look like the field dogs that are popular here. The field dogs here push 100 pounds or more.
Tori is probably at the small end of the scale - she's about 1/2 inch taller than Shelley but MUCH longer in the back and about 10-12 pounds heavier (Shelley looks chunkier because her back is almost six inches shorter than Tori's - we measured) - but around here our field trial bitches tend to be about 55-60 pounds and the boys around 75-80. But of course they are very thin, they are kept lean on purpose, on a lot of them the ribs are visible. 90 pounds is considered a way big dog -- one of the guys in the club wound up with one, good old Ranger, who is a sweet dog but TOO BIG.
