labrador puppy size
I got a female labrador puppy yesterday, that the people said is 8 weeks old. From what I can see from the internet the minimum weight is around 10lbs (4.5 kg) but I doubt if she''s even 2kg. She looks exactly like a labrador, but now I''m wonderding if she could be crossed with a smaller breed, or if the owners lied about her age? Is there any way to see if she''s younger than they claim?

Hi Kelly

It is possible for your vet to age a puppy from it's teeth development

Estimated Age - Teeth Development
2 - 4 Weeks - No Noticeable tooth growth

3 - 4 Weeks - Deciduous (baby) canines erupt

4 - 6 Weeks - Deciduous (baby) incisors and premolars erupt

8 Weeks - All deciduous (baby) teeth are in [14 upper, 14 lower]

3 1/2 - 4 Months No noticeable permanent tooth growth
(it is all under the gumline, not visible)

SO... an 8-WO puppy will have *all* their teeth EXCEPT their molars, top + bottom...

all the incisors, all 4 canines, all pre-molars are present.

adult incisors erupt between 3 to 5 mos;
adult canines erupt between 4 to 6 mos;
adult pre-molars usually erupt between 4 to 5 mos,
and molars are last, between 5 to 7 mos age.

If you are uncertain then ask you local vet or veterinary nurse to check.
