If you have found an animal the first thing to do is contain it.Â
Its not usually beneficial to 'chase' any animal and do not do anything you feel uncomfortable with. If you can take pictures and share them on the Facebook group and watch the animal while others come to help.
If you can keep hold of the animal until their owner is found then great, if not you can enquire with the local vets if they have space to hold or the Council Dog Warden. Our of hours North Clwyd Animal Rescue can usually help.
