This is a Portuguese pointer (Perdigueiro Português).
They are a red-legged partridge dog from Portugal. The red-legged partridge (Alectoris rufa) is a close relative of the chukars (A. chukar) that have been introduced to North America. They are common game birds in parts of southern Europe. In English-speaking countries, they are sometimes called “French partridge.”
The Portuguese pointer was bred as a hunting dog for the nobility, but they later became common hunting dogs for the lower classes– something like a Portuguese Brittany.
No. It’s not a cocker spaniel/bulldog mix!
