Sorry to be late in discovering the lovely photo of Tatiana holding / cuddling a puppy : it is a brindle French Bulldog puppy, 99% sure. French Bulldogs puppies are very tiny when they are born, they can go their new home at the age of 8 weeks. They are teenagers between 6 months and about 1 year old, and change a lot. Frenchies are generally at their best around 3 years old, though boys generally mature physically quicker than girls.
Tatiana received Ortipo as a present from Dimitri Malama in October 1914 and she must have been a puppy of this size I guess. As to Ortipo's own puppies who were born about one year later, they were crossed breed, no one knew who the father was and the poor things were said said to be "ugly".
On another note, one has to know that the breed changed a lot between its origins around the 1880 and nowadays. To day 's Frenchies are larger, far too large in France in my opinion. I have had French Bulldogs for years and like them small and cobby.
This should be in the Tatiana and Ortipo thread, I guess. However I felt that this infos would be of interest for some members.
