good question. on the internet (and with most desktop systems), no one would know if a user was a monkey or a dog. CAPTCHA, logins, etc. all have their drawbacks but they still work to some extent. we're still far away from personal digital certificates and unique identifiers of old such as SSN's (anyone who went to college in the 80s' will remember their SSN was also their college ID!) are prone to forgery or theft.
have you looked into SMS messaging or verification? privacy issues aside - it could at least be traced back to a human since last i heard dogs can't use cell phones.
