hi ya im in kent gravesend where abouts are you in kent?
id say the mum looks full to me but has got big ears but then again 350 is a good price for a pup, if you look on epupz you will see the different price range.
pups should be seen by a vet b4 you take them and have there first injection, pup should also stay with the mum untill about 12 weeks to be on the safe side.
good luck
