Are any of your cav's scared of overly tall men? or even just tall people in general? Our friend Matt came around to pick up his partner yesterday and Charlie barked like anything and seemed a little scared. They have met at least fve times before and in the past he has been a little hesitant when he arrives (although nothing we worried about till now).
Charlie has not had this reaction to anyone else.... and our friend Matt is taller then anyone else he has met in our house by a large margin. We just gave Matt some treats which seemed to do the trick and while still a little bit weary it at least calmed Charlie down.
