How can my ex wife stealing my dog be classed as civil matter when the theft took place a year after receiving decree absolute?

The theft of your dog can be classified as a civil matter because, despite the decree absolute, ownership of the dog may still be contested in civil court. In family law, pets are often considered property, and disputes over their ownership can fall under civil jurisdiction. If you can prove that you were the rightful owner or that she took the dog without consent, you may have grounds for a civil claim. It's advisable to consult a legal professional to explore your options based on the specifics of your case.
