How best to permeate contained by holes dug by my puppy? My dog digs holes on occasion when he's not here in the...

My dog digs holes on occasion when he's not here in the patio. It happens when there's mud or he think he sees something moving surrounded by the dirt or grass.

Now we have several pretty thoughtful holes and lots of smaller ones in the patio, and I'm afraid if I fill them near dirt he'll just be enticed to verbs there again. I'm trying to train him to stop this but that's a separate issue.

So does anyone know an efficient way to crawl in these holes so that not a soul will break an ankle in my courtyard? Thanks!
Answers:    Buy a shovel, if you don't already have one. Use it to teem in the holes. Repeat as vital.
