I have just bought 2 pups from a breeder 1 is slightly older 4 mths other 3 they are both gorgeous but i am wondering if the older pups head shape is ok its quite dome like between her ears wgere as the younger pups is flat is this normal? The breeder has assured me it will flatten out but u read some scarey stuff so looking for other opinions as obviously its alot of money to spend on a pup who may have potential problems any advice appreciated
