I grew up with large and small dogs since I was young. My first dog was a pitbull so no I don’t think they’re dangerous, so much so I own a cane corso now. I love all types of dogs and rescued a few strays to give to new families. I have done the same with cats and birds, yes birds. I found strays from new born to even elderly, took care of them and learned how to do basic grooming care like clipping nails and trimming coats. I train my dogs pretty well, I’m not no professional, but they know many key tricks perfectly.
