Hi, I bought a bulldog last week from classified from a family near were I live. My dog is 3 years old, they said it was an old tyme bulldog, but they gave me a registration paper from the new england bull breed registry which says the breed is old english bulldog. What is the difference? I have seen that there are different types of old tyme bulldogs, dorset, alystone etc etc or a olde english bulldog, leavitt bulldog. I have uploaded a picture anyone know the strain of bulldog mine is from the picture ? He weighs 34 kg and is 60 cm high. Any feedback would be great, thanks.
