To Mewzard //"No problems, it was a really good point for me as it's helped me see Oka's behaviour in a nature vs behaviour way."// OH yeah, i hear you there, Mewzard. I find innate and inherent behaviors fascinating. Like you, i find it helpful to know which ones are almost 'default' prewired tendencies. I have saved that link btw, it was just too cute. I may have to pick up one of that authors books for next time i treat myself to a fiction book. I bet they are fun reads. To Rosiemom: //"Maybe she is shy??? But as long as I have known her she has never snapped except..."// Not all shy dogs show any aggression. Shyness mostly refers to a dog who does not enjoy contact, being touched by, unknown humans. There are many levels of SHYNESS. It's genetic, and it is permanent, on some level, for life. It's not your fault, Rosiemom. It's not something you did "wrong" raising Rosie. But you can make Rosie better, or worse, by how you manage Rosie's shyness---that is -------IF IF IF Rosie is shy, (can't really tell online.) But, when a shy dog DOES escalate to the point the dog displays aggression, often, their primary and lifelong target is HUMANS, not other dogs.................... not like my dog's condition. My dog has "dog-aggression", and HIS primary target is other dogs, not humans. It's two different disorders, with two different targets, and really, the approach and goal for each type of dog is a lil different. In MRIs, the shy dog brain and DA dog brain, do not match each other. The methods that help a DA dog, might not help a shy dog, and vice versa. But, most ppl lump "all aggressive dogs" together in their minds, but, it's two different kinds of aggression, and in some ways, the two types of dogs are opposites. But shy dogs can also develop aggression TO DOGS as well, so if i were you, i'd do whatever i could to keep your sweet lil Rosie away from dogs like my dog, who may be in your aggression-class............... there are probably some d0g-aggressive dogs in Rosie's class............ But a dog can by shy, and never ever growl or bite anyone. Many shy dogs live their entire lives, and never aggress to anyone, especially if their owners understand shyness, and take steps to prevent the dog from having to put up with unwanted contact, the dog is less likely to feel threatened enough to resort to aggression. The shy dogs who are SEVERE cases, or who are forced to try to "get over" being handled by humans, are more likely to turn to aggression. Not all shy dogs are aggressive, and even the shy dogs who ARE aggressive, can have their aggression reduced. Proper management, IF IF IF Rosie is a lil mildly shy, can help prevent or reduce any tendency for Rosie to feel she has to resort to growling to keep ppl back at a distance where she feel safe and comfortable.
