When looking at which of the dogs makes a better family pet, their temperament certainly plays a big part in the decision, however, part of this eligibility lies on both you and the dog’s breeder. Sure, the GSD is known to be a bit more aggressive and serious, but so is the Blue Heeler here, albeit to a slightly lesser extent. That is, unless you provide them with early behavioral training. Much like with humans, it’s important to allow your dogs to build up social bonds as pups and to be taught about what’s okay to do and what isn’t at an early age by having them hang around fellow dogs and young children. The earlier it’s done, the better the knowledge sticks and the easier it’ll be to have your dog act in a friendly manner toward both kids and other dogs, avoiding any potential accidents and discomfort. And both sides have a lot to learn. The German Shepherd’s fault often lies in his overprotectiveness towards the kids of his owner while being extra wary of other dogs and strangers, even if they’re distant family members. The Blue Heeler, on the other hand, carries more of that herding mentality toward kids and is more likely to nip at their heels to get them to stop misbehaving, as if he’s corralling cattle, though he isn’t the biggest fan of strangers either.
