Recently bought a lab pup

I recently bought a lab puppy and he is supposedly 6 weeks old and has his first set of shots. Admiral (my pup) is as small as a 3-4 week old lab. He's tiny an you could see ribs and hip bones when I recieved him. Can anyone help me determine his age and/or if he looks like a full blood lab? I'm using a cell phone and not to sure how to upload pics. So if someone could help with that also that would be helpful.

 

Ashlin, I really understand that you must be having a very worrying time over this.....
Whilst we understand that situations arise,puppies should be with their mother and litter mates up until the age of 8 weeks.
Please take this puppy to a vet immediately for a check up and some urgent advice for its care.

Moderator Note:

Sadly, in some parts of the world there is a tragic trade in tiny puppies barely able to walk. On the Labrador site we frequently get comments from people who have purchased puppies as young as 21 days old. Their owners will usually need help from a qualified veterinary professional if the puppy is to survive and thrive.

Our forum policy is to encourage people to wait until their puppy is eight weeks old before collecting it from the breeder. To make sure we are not encouraging the trade in underage puppies, nor depriving these puppies of essential veterinary attention, we have the following rule.

If a forum member’s puppy has been removed from the breeder/ mother before the age of seven weeks, that member must wait until their puppy is seven weeks old before posting about him or her on the forum

We recommend that anyone with a puppy under this age contacts their vet without delay for instructions on feeding, general care, and medical treatment. We understand that members want to help these puppies, but the forum is not the right place to be distributing specialist advice of this nature.
