@Sempf big dog attitude and little dog attitude seem to be instinctual from birth, independent of whether the future big dog is big yet or not.
and weiner dogs are small dogs but have big dog attitude, they're not afraid of Odin
@[email protected] @[email protected] My grandmother used to train great danes, an other type of large dog with a generally good temperament. Nearly all small little dogs (puppies or just smaller breeds) seemed entirely happy to play with, try to threaten and/or, for the adult dogs, romantically engage with the danes despite it being obviously physically impossible for them to impact the danes at all (many of the smaller dogs were shorter than the danes' knees). That did rather immediately change on the one occasion I saw a dane get actually angry with a smaller dog, but even then the caution only lasted as long as the growling did.
