He looks like a kit beaver, lol
. I love labs, great dogs. Here is our "office" Willie on post. He's a comfort dog for one of our active duty officer vets that has seen and experienced too much during his tour. The name fits a chocolate for some reason and Willie has rapidly became a comfort pup for us all. I vote Willie 
As I type this my son's border collie / aussie cross is curled at my feet. We take care of him a couple of times a week when my son pulls 12 hour graveyard shifts at the hospital. His name is Archer, which I didn't care for at first but now has really grown on me. We will also call him Archie or Arch. The name has a bite to it when you are trying to get the dog's attention. He responds well to it. Archer's dad is a full border collie and a PTSD therapy dog for a friend of my son's. Archer's dad has been called the "coolest dog on the planet" by a lot of people. He follows his owner everywhere she goes, including the classroom in college.
I have to come up with a female pup name. I will pick up my BLF from Lee Salmon at Wind River Labs in March. This is our first dog since my big BLM boy Hoss died in 2016. Hoss is a great boy dog name if your pup is a big guy, as Hoss was...92 lbs at his prime hunting weight.
