 Larger dogs are more likely to engage in more aggressive behaviour when their conspecific is smaller than them while they are less likely to interact with their conspecific if it is larger than them.This type of behaviour also transfers over to smaller dogs, in which are less likely to interact with any other conspecific at all if they are in any way larger than them which is likely due to their distinct disadvantage of body size.In bears almost all vocalizations can be wrongly classified as a growl.
