whilst at the vets today i saw a gorgeous puppy, it was 5 months old, and looked like a shar pei, but it was the size of a big adult lab.
Sandy fawn colouring, quite wrinkly.
Didnt get a chance to ask owners..

any ideas what breed it could have been?

Perhaps it was a dogue de bordeaux???.  Not sure what they would look like at 5 months but am sure they would be about the size of the puppy you saw.  Anyone else got any ideas??

hmmm....i'm not sure what kind of dog that was, but you could call your vet's office and ask the receptionist what kind of dog it was.  i'm sure they will tell you if you describe what you saw.  good luck finding out.

Dogue de Bordeaux of Neopolitan Mastiff ??

A sandy fawn colouring? would that not be just a bullmastiff?
