Hello!
As a dog parent myself, I can absolutely relate to wanting our furry friends to be as free as possible. It's understandable that this regulation is a point of concern for you.
According to official guidelines, a public place is generally considered to be anywhere outside a private home or premises. This would include hiking trails and camping grounds. The regulations are designed keeping safety in mind.
I believe you can find some relevant information on the
Citizens Information website.
Hope this helps with your planning, and I wish you and your lovely dog all the best! 🐶😊
