After our previous dog (83lb plott hound) passed away in December at age 12, we were not in the market for another dog this soon. But when your offered a free puppy from a rescued litter how do you pass it up. This is Winston the Boerboel. He’s also known as a South African mastiff and we are estimating he will be around 150lbs full grown. So far He’s very laid back and eager and excited to meet anyone and everyone. We have been trying to socialize him as much as possible because these are bred to be guard dogs and can get aggressive. Does anyone have experience with giant breed dogs? Any dos and don’t s compared to other breeds?
