A friend of mine with two Samoyeds was alarmed by a pit bull attack at a park near her in which three pits were being walked on leash, two got loose and the owner ran off with the third while a jogger was hospitalized after they mauled him. Police are still looking for the pit owner.

I've known some very sweet pits, terrible shame that they became popular with bad people.

I've long carried pepper spray when walking my dog to protect her from off-leash dogs. Never had to use it but did once threaten to when an owner failed to call back his German Shepherd who was approaching aggressively.
