I don't know much about Shibas, but, from what I've heard, they are NOT the type of dogs to tolerate a 13 month-old's poking and prodding. Shibas are independant, cat-like dogs. Therefore, I must disagree with DIANESDOGS. While Shibas are loyal and affectionate with their own family, they are often aloof with strangers and can be aggressive with other dogs. This does not, however, mean they are "kinda mean" and nip other people for no apparent reason. Only poorly raised dogs do that.

Shibas aren't often recommended for first-time dog owners so if you are, I'd suggest you contact a reputable breeder before you make a decision. Chances are they'll probably talk you out of one because, though small in stature, Shibas have a lot of spunk and they're often too much for young children/first-time owners.
