You know how most dogs howl when an ambulance or firetruck or police car goes by?!...not our lab collie mixes...that sound does not seem to bother them in the least...
Taz and Mysti howl and go nuts when a train goes by...and not just in the beginning when it whistles, but the entire length of the train they carry on out there...
Yes, we have railroad tracks about 75 feet from the house...I have said before we live CLOSE to a grainery...
Most of the time, I do not even hear or notice it going by, if not for Taz and Mysti carrying on like they do...
