This letter is directed toward dog owners who choose to take advantage of the many great places on the Cape that are open to dog walkers this time of year. Taking Fido to a beach or conservation area (good idea) comes with a responsibility to be in control of your pet. Letting your big old dog go gamboling down a path 50 yards ahead of you (very bad idea) can create a situation that gets out of control quickly. I, for one, am tired of having to separate my 20-lb. dog from a growling animal three to four times her size. So please, consider the possible consequences of your actions before you decide to let your usually friendly buddy take off down the trail.
