Size Genetics – “But I want the BIGGEST puppy!”

Size Genetics:

This is your lesson on Size genetics.

Size of  a dog is based on genetics.  It is NOT based on the size of the puppy at 8 weeks of age.  This is why I make it a point to tell my clients over and over DO NOT pick your puppy based on the size.  DO NOT worry about what puppy is larger and what puppy is smaller.  Pups grow at different rates, develop at different rates, just like children do.  Think about infant birth weights… will a 9 lb. baby necessarily be bigger than a 6 lb. baby as an adult?  Not at all! Bigger puppy does not equal bigger adult dog.

Pictured above are two black female pups from Erica and Ch. Endless Mt. Mack Truck, “Mackie” (the largest dog in our kennel!) The little one, Abbey, was the smallest of the bunch.  Not all 8 week old puppies are always the same size.  There are so many factors to affect the size of young pups.  Richness of mama’s milk, size of litter, etc.  And like I said, puppies grow at different rates.  She was, however, the BIGGEST sweetheart!  (We all doted on her because of her pocket-size!)

Below is a picture of Abbey at 4 months old, sent to us by her family.  As you can see, she is no longer pocket-sized!

When it’s time to pick your puppies, remember this information.  NEVER be concerned with the size. We breed in Lab Standard and our pups grow as they should.





  1. Very interesting. My first lab was one of the smallest of the litter, but he grew up just fine.

  2. Hi.. I’m writing about Brodhi (BrickxHero). He is 91/2 months and 88.1 lbs. I’m being told he’s overweight but I’m not sure since I’ve never had an English Lab before. I feed him a really good food but am not sure if I should be feeding him Large breed puppy food. Any thoughts? BTW we feed him Wellness Core puppy food and he’s doing real well on it.

  3. We had a litter of “Goldadors” a few years ago. They are Golden Retriever/Labrador Retriever hybrids. The runt of the litter was just over for a visit.. She was literally half the size of the other pups. Well, she is 3 years old and 90 libs of mush now. The pups now range in size from 63-92 libs. They are a fantastic hybrid. They look identical to the Father who is an English Lab with the exception of having the tail of their Golden Retriever mother.

  4. Love your Blogs: When I picked up my puppy 10 yrs ago. Both females in the litter were close to the same size.. My girl Tique is beautiful, looks like an English Lab, however she stopped growing at 18 1/2 inches, The rest of the litter all ended up within Standard.. Her size actually turned out to be a positive. I receive comments
    and questions, constantly, asking what breed she is. Labs just are not that small,, says most commenters. She is perfect in my eyes.

  5. My family has bred golden retrievers for generations, I wanted to pass on this info in case it helps someone pick the right puppy for their home. Size does matter, but not the way most people think. The biggest (usually fattest) puppy is usually one of the more dominant pups, and the runt is usually the most submissive. If you want the biggest or smallest puppy for full grown size, look at the paws. Bigger paws at weaning make bigger pups, and smaller paws make smaller pups. My family has always preferred larger goldens, and using this method, we’ve ended up with a much larger family line, with one dog approaching the size of a newfoundland. It’s not 100% accurate, but it’s better than not having a method at all. Hope it helps 🙂

  6. Well I don’t agree. I’ve had the largest puppy in a
    Litter than became the largest adult dog and I’ve also had a runt thAt always stayed a runt. So I don’t
    Think it was a coincidence
