Garden and daily forest walks

I have had dogs all my life. I live in Enniskerry, and am very close to forests and fields for nice walks. I have a little working cocker spaniel, Millie. She is very friendly and energetic so we go on daily walks. I have a secure garden that the dogs can access throughout the day, I usually leave the door open so they can roam freely in and out of the kitchen. The dogs sleep in the kitchen at night. I am a dog lover, and love to have the company of another dog for Millie. I have minded my neighbours dogs and friends' dogs multiple times. Preferably wouldn't take larger dogs. I would expect the owner to supply dog food for the duration of the stay.
