Yes, cane corsos are hard to train. While they are an intelligent and loyal breed, they are also known for being stubborn. In addition, their size and protective instincts make them unsuitable for first-time dog owners or anyone who doesn’t have the time, energy, and experience to train and socialize them properly.
Cane corso puppies get bored quickly, so they need short, clear, and fun training sessions, ideally every day, to help them understand what they need to do and not do. Plenty of exercise and enrichment activities, ideally playing with other dogs, will help your cane corso burn excess energy and relax.
In addition, given their strong prey drive, cane corsos should be socialized with cats and other pets from puppyhood to avoid causing problems as they grow.
So unless you’re a skilled dog trainer and want to devote plenty of time and energy to training your pup, a cane corso is probably not the breed for you.
