Tonka went to the vet today to get puppy vaccines. He is 9 1/2 weeks old and weighs 16.4 lbs. He's a big boy. The vet said that he is a very healthy puppy. My parents took Tonka's brother, Hudson, to the vet on Monday and he weighed in at 12.8 lbs. and the vet said he is healthy as well. Just thought I would share.
