Amstel is a 100 lb cross between a pyrenees-mastiff and an Australian cattle dog. Strikingly handsome, of course, and a “singer,” too! While we were dog sitting for him, we got to hear his beautiful voice, “singing” along with ambulance sirens. Now, where does that come from, why is this dog singing? Is he just joining in, is he annoyed or bothered? Wish we knew, but we enjoyed it, nonetheless!
