A relative bought herself a Chi a few years back, the first time I went to pat it, it nearly took my arm off, it was about 10 weeks old If I come across one I think how cute but no way would I try and pat it. I also have a little terrier "thing" she actually resembles a meerkat so "thing" is quite an accurate description, anyway, if she sees a human she will drag me towards them but it's only to say a friendly hello and try and worm a pat out of the stranger if they are so inclined. People do ask me if she bites before they touch though. Small terrier "things" have an impressive reputation
