I took both of my Shibas to the course the guide dogs run here in Launceston. I know Shibas can potentially be dominant so socialisation was always on the cards from day one. Loki, my first is a submissive quiet boy (Ok! he is a mummys boy, and proud of it!) He was totally un intersted in the other dogs. Would just sit and sigh and look the other way whenever another dog came up to say hello. The lady running the course kept using him as an example of "the more aloof breeds" yeah, thanks . A few years later I took Wylie to the same course. Little beast has attidude issues, ie- he is god. (normal shiba) I spent the first few weeks sqirting him with a water bottle cause he didnt stop barking and trying to push around the wimpy pups. These courses just run through the basics. But they do seperate the class into two age groups rather than size. Puppy and adult. Which means you get all breeds and sizes running with each other but more in keeping with their development. Wylie didnt learn any manners till I started walking him to the off leash area and he tried to bully two young labs who thought the funny little barking thing was great fun and tried to roll him into little balls. No aggression from them at all, but he sure learnt he wasn't god and other dogs might just be bigger than him! It was the best thing for him. Now days I just have to watch him around the little girl dogs.....
