Apart from the possible resemblance to a banned breed another care you must take is with two puppies the same age. Rearing two at once is more than twice the work of one. This is because you should take care to work with them one on one and do much of their training separately. This is even more of a concern with the temperament you may expect to find in your chosen breeds, they need to be very thoroughly socialized and habituated and they will need much of these as individuals, not as a pair. As a pair the danger is they will bond more to each other than to you. For this reason many, many breeders will not allow puppies to go as pairs to a purchaser.
Dogos are not recognized in Canada so there is no Canadian standard. The FCI standard says this about colour:
COLOR : Completely white; only one black or dark coloured patch around the eye may be admitted, provided that it does not cover more than 10% of the head. Between two dogs of equal conformation, the judge should always choose the whiter one
I also think the photo of "Dad" looks more like the Am. Bulldog. Benmax? Opinions?
Cutie-pie puppies. Oh so cute.
