How to contain puppies in the compound?

Puppies are friendly and playful to a fault. They befriend everybody testimony of their big heart but also lack of cognition. Some people have lost puppies after they make their way out of the compound due to their adventurous nature. In other circumstances, puppies follow their owners with them being unaware for a long distance. This exposes them to all sorts of hazards including being run on by vehicles. On the other hand, its not fair to contain them in kennels. What to do?

 

Our property is fenced all around so it is safe for dogs to be loose. In fact, when our dogs were still puppies, we let them freely roam the compound, from the front yard to the side of the house and then to the backyard. That roaming around is a good exercise for the dog particularly for the puppy. However, there is always someone watching over our dogs when they are let loose. Their habitat is the inside of our house where they are safe from the elements. And we let them loose in the yard at least 4 times in a day for their exercise and toilet habits.

 

Our dogs have free rein over our front yard which is good because they can exercise and play to their heart's content. We have a wall fence around the house and anyone who goes out of the house locks the gate so there's no chance that any of them could go out without us not knowing. I would never want to chain them to kennels, too. They are both cutey pugs who like to cuddle.
