Our lab just turned a year old November 15th and weighs right at 100lbs. I have never had a lab this big and was curious if there is a larger breed of lab. His dad was the biggest I have ever seen but his mom was a short legged lab and both were pure breed and registered. I will try to add a picture I have of our lab at 9 months old.

I'll give you my very limited knowledge of the breed. Yes there are 'english labs' that are shorter and stockier. The only reason I know this is I took our female yellow lab to the Canton Trade days and was stopped by a lady who said she was a breeder and that I had a fine example of an 'English Lab'. It was news to me at the time as she was a pup that was dumped in the country near our home and chose to live at our house. The american type labs I understand are taller and larger. I'm sure more knowledgable people will chime in here for more help.

There are not different "breeds" of labs. But different "types". There isn't supposed to be, but unfortunately with the ranges in breeding ethics and purposes for breeding, there are a lot of variations of Labradors. The typical types fall into show (or English/Bench/Blocky heads/stocky), field (American/Lanky/long snouts), or Pet Bred, which is a mixture of the two, or nothing at all. Unless your breeder actually shows in the conformation ring or regularly runs Field Trials or Hunt tests, more often than not, your dog is likely a pet bred dog and it will vary greatly in size.

I had a phone inquiry yesterday from someone looking for a chocolate female. She had been referred by several folks to me... after we chatted a bit, it came out that her choc male was 110#. I told her I didn't breed that size, or even close to it, even if I did have any chocs available (unlikely for this litter due in 10 days). Anyhow, I proceeded to explain what the standard called for w/ regard to weight (~80# for males), and how added size tended to increase the chances for joint issues. It sounded like she had a mini horse, and since I started out w/ bigger field lines years ago, I do tend to be a little sensitive to that! Some folks just seem to think "bigger is better" but they couldn't be further from the truth, really.

Are you saying I should expect joint problems? If so at what age? My labs dad is 5 and has had now issues. My lab isn't fat he is very lean and muscular but I have never seen labs as big as my or his dad before he is my 3rd lab and the other 2 only were around 60 to 70 lbs. I was mainly curious where this larger line of labs come from.

Does the Sire and Dam have their joint clearances- OFA for Hips and Elbows?

Having multiple generations of normal Elbows or Good or Excellent Hip (Fair is also passing) ratings decreases your chances of orthopaedic issues for your dog. The breeder should have given you a copy of the OFA ratings, if they did them. Otherwise, you can go to the OFA site and look up your dog's Sire and Dam and see if there are any clearances. http://www.offa.org/search.html

Unscrupulous breeding.

The faster the growth, and bigger the dog (no matter what the OFA background from what I've seen in the old field lines), you have more risk of having issues. Dysplasia means "bad fit". All puppies start out w/ normal joints but the faster they grow, the more risk there is that things will get out of sync. His growth is probably mostly done now, so there may not be a lot you can do at this point besides just keep him well exercised (free exercise is best for conditioning) and lean.

I was told long ago that it was more risky to breed 2 extremes together (big dog to small dog) as well-- better to reduce size thru gradual transitions. That's what I did, and i sure don't regret it. My first bitch was not big herself (only 21.5"), but she sure produced some monsters. :( One local guy who imo, got lucky w/ his big boy (aged rather well-- 13yo now and was 110 in his prime, and at least 25-26" tall), still wants a pup that will be a big dog. I told him to go fish... my boys are now more like 75# and 23" on average and I don't plan to change that as I don't like hearing about issues.
