Our dog goes nuts anytime we start any type of engine like a lawnmower, weed eater, blower, or boat. She will bark like mad and then calm down after it has been started for a minute. We have to make sure she is not around when weed eater is started because she tries to bite at it. We like to take her out in the flat boat and she happily jumps right in, but it is really obnoxious to get through the first minute of nonstop barking after starting the engine. Has anyone else had this problem or know what she is trying to express? Any suggestions on how to change this behavior?
