What a shame, that must be really difficult. You just highlighted my pet hate too, owners with their dogs off the leads. Especially little, yappy, fluffy ones who insist on running right up to Lola. One of them even said, don't worry, he won't bite her!??? Although Lola was ok I was so glad she had her muzzle on, just in case. I notice she doesn't react to small furries. . . Until they run away from her, then she's very interested, especially if it's a cat!
