Hey everyone, so im the new one here. I just went to the breeder I'm getting my Labrador Retriever puppy at. And I found lovely puppies. So I chose the one I wanted, the dark green collar one . But im just wondering if its normal for her to sleep a lot. She wasn't too energetic when I first arrived at the breeder's house. However she did play with her littermates, and she did interact with the humans. We were there for about 45 minutes and she starting sleeping the last 10-15 minutes? And she wasn't sleeping with her littermates, she was sleeping by herself which worries me. But I checked her eyes, nose, ears, and bottom. They were all clean and healthy and her fur looked shiny and healthy too. But she was definitely one of the less active ones. There were a couple that were just jumping around everywhere. They are 4 weeks and 5 days old. Please reply any comments to reassure me. First time puppy buyer. Thank you.
