Reactive to buses
(Calgary, Alberta, Canada)
Mary, my 3 year old Pyrenees, has been lunging and growling at busses and some other vehicles occasionally during our walks. She only started this about 6 months ago. I adopted her from a rescue group at one year old and she grew up on a farm. I knew she would have to get used to the city noises, etc., and she never had a problem before now. I do not recall any vehicles aiming towards us at any time on our walks. There does not seem to be any real reason for this as it appears to be very random. Sometimes she is just fine. Any ideas as to why Mary reacts this way sometimes and not other times? I had her checked by the vet, but she is very health.
