People are still bringing dogs in the park and leaving it after them. It is disgusting for people coming to the park to sit around and have to be very careful not to step on the remains. Are dogs allowed here ? Or its just the board which says it?

Dogs are allowed in San Diego city parks so long as they are on a leash. They are not allowed on rhe playing fields. Dog owners are supposed to pick up after their dogs. It is unfortunate that some dog owners chose not to be good neighbors and park patrons resulting in less than pleasant park experiences. As for the sign no dog sign, it could have been either a no off-leash dog sign, or a no dog on playing field sign.

But i saw the board saying dogs are not allowed so im little confused.

Dogs are allowed. Dogs are often brought to the park to play and walk
