Just call me Mac!
Mac is "First Dog" and as such, has the responsibility for worrying. He does this a lot. Worrying involves investigating and barking at every noise, alerting humans that people are entering or leaving the house and ceremoniously slinging drool on all visitors while sneezing madly. Mac's favorite activities are hiding when the humans are getting ready to leave, keeping his toys away from Tosh and drooling.
