I couldn't find the decibel measurement of a puppy's bark, so we'll go with grown dogs. The world record dog bark was set by a white German shepherd at 108 dB. It isn't fair to use the record holder, so we'll assume an average of 100 dB. The dB limit at Laguna Seca is 92 dB, which seems very low. Also, neither Guinness nor Laguna Seca's site listed how they measured, so I'll assume it's at 1 meter, since that's the standard.
Since decibels change on a logarithmic scale that requires double the power for a 3 dB increase and half the power for a 3 dB decrease, then 1/8 of an adult German shepherd will produce 91 dB and be legal to run at Laguna Seca.
Math, bitches.
