Encounters between dogs and deer can happen unexpectedly, so it is important for owners to manage their dogs carefully in these environments.
Most deer will try to avoid people and dogs. However, if they feel threatened or if a dog chases them, the situation can quickly become dangerous for both the wildlife and your dog.

In Ireland, dog owners are legally responsible for keeping their dogs under control. If a dog worries livestock or wildlife, the owner may face penalties under Irish dog control legislation.
