Yes, blue nose pitbulls are easy to train. They typically obey new commands after 15–25 repetitions and obey known commands 70% of the time.
In terms of obedience, they only rank as the 48th most intelligent breed, perhaps because they have a stubborn streak like most bulldogs.
However, obedience isn’t everything, and blue nose pitbulls (like all pitbulls) are known for their high adaptive intelligence. This means they can learn for themselves and make their own decisions based on a given situation – they don’t only rely on commands from their owners.
