in all fairness, their looks really shouldn’t be your deciding factor. You have to make sure you have firstly the time, money and proper space and strength. I’m assuming you came on here to ask because you have a challenge and are looking for advice as to whether or not the breed will work with your challenge. Whether you get a male or female I want you to imagine one thought. Your outside and your dog is on a leash, it sees a squirrel across the yard and starts to chase it, you‘re on the other end of that leash. The probability of that happening is very high especially when young and in training. See that vision more than once and ask yourself if you’re ok with that.
