In Delaware, dogs are not allowed to run at large unless in situations when the owner is present and has control over the pet. An exception is for farm dogs. Also, during the night dogs must be kept in an enclosure from which they cannot escape, firmly secured with a collar or chain or other device, so they cannot stray from the premises, or are under the reasonable control of the owner or custodian. If an owner does not respect these laws and if the dog bites someone, the owner is subject to civil liability and for fines of up to $1,500.
