Whenever you go to local parks or baseball fields, there is always a big sign stating that dogs are not allowed inside. Why only dogs? Just because they are the most common pet to have among Americans, it still does not justify why other animals can be let in. What if you had a cat on a leash? Would this animal be allowed to enter? What about a pet alligator, snake, rat, turtle, bunny? The signs should be changed to be fair and not discriminate against dogs and their owners.
