I have an 11 year old yellow lab. He is about 110 lbs. he’s a big Goof. But he still acts like a puppy. I also have a lab/retriever mix. She is a bit smaller but still big. About 90lbs. I grew up with labs my whole life so I’m pretty biased. 😉. Even though the lab I had growing up was an amazing duck hunting dog he was the nicest dog in the world. But once the camo got broke out he would go nuts.
