In California, dog owners have a legal obligation to ensure that their dog is under their control at all times. If the dog isn’t in a fenced in yard, it must be on a leash that is no longer than six (6) feet in length. That being said, there are designated dog parks where owners may allow their dogs to play off their leash, but the dogs must still be supervised. Violating the lease law could result in a fine of at least $100 for first offenses. If a dog bites someone, the owner may be held legally liable. The victim may be entitled to receive financial compensation for the bite.
