I have never heard my dogs howl. When I was a teenager I had my own dog and she wandered and killed a chicken so had to be tied up for a while so she howled. My mother told me that if she ever heard her howl again she would have her put down as it was a sign that she was going mad and she might attack us It is so scarey how these old wives tales take root. I wonder what the vet would have said if he had been asked to put her down. I was terrified, that dog was my life, I couldnt believe I might lose her but thank goodness she never howled again.
