Stubby was a pitbull and is in the Smithsonian in a glass case.
Stubby must have been a pit Boston mix then, I’ve had Bostons all my life, and I see Boston in his features.
Stubby was of some kind of pit bull, but Bostons were new and not like now, often called Boston Bulldogs or Boston Bull Terrier. They were of fighting dog stock. However, Stubby was decorated purely for fun by Pershing and was really nothing more than a mascot.
