To address the problems the lady faces with Harry and Toto, management has to come first. Harry is an 8-year-old terrier, and Toto a Bichon Frise age three.
Over the years, Harry has bitten several times when out, including a child. Fortunately so far he has done little more than to break the skin.
Toto, a more recent rescue, is fine outside the house, but may go for the feet of anyone moving about indoors.
