My friend's field chocolate next to my black Logan, who was an inch taller than the standard, BTW.
They liked him that big up here. I've seen a lot of them.
I just took a look through the latest issue of Hunting Retriever News, the official UKC/HRC magazine, for the stud dog ads (the boys being generally larger than the girls). All these dogs are very well bred - the ancestors listed are all GHRCH, FC/AFC, grand passes, and so forth.
Chocolate dog with Way-Da-Go Rocky, Barracuda Blue, and Storm's Riptide Star (Shelley's grandfather) - 70 pounds.
Black dog with Trumarc's Zip Code, Rogue River, Rebel Ridge, and Wilshire's HonestAbe - 75 pounds.
Here's a funny one - five littermates who all made HRCH or better and all passed in the 2006 Spring Grand, the above stud dog and his brothers and sisters -- 75, 70 dogs, 60, 45, and 40 pounds for the bitches. (The littlest sister is advertised as "40 pounds of testosterone." Must be fun!)
Black dog with Ebonstar Lean Mac and Gunstock's Lethal Weapon - 65 pounds.
Chocolate dog with Candlewoods Super Tanker/Cajun Dakota breeding - 90 pounds. The only 90 pound dog I saw advertised at stud.
With the best of the best (the big UKC performers with multiple Grand passes and plenty of FC/AFC and GRHRCH back of them) it seems like 70-75 pounds is typical.
