It would be good fun and stimulation to teach your children to teach Sparky not to run away. Start with some basic training, sit down, stay and recall. Don't forget Cavaliers are like little toddlers and need direction.
We use a baby gate between the door to outside and the rest of the house which stops accidents. I also found online cheap agricultural fencing which secured the boundary of our garden.
Sparky is at risk of being run over, so training is needed for the whole family urgently.
I love his profile picture, he looks adorable.
