What is a good way of keeping my dogs out of my flower beds?

I've put up decorative 2.5 foot high fencing around it and the dogs still jump over and ransack the flowers. I've also got a 3 foot tall fence around my raised pond, but they still somehow manage to "levitate" over and into the pond.

I had this problem last week and this is what I did. So far this is working. I am sure I will have to reapply when it rains but this is pennies on the dollar compared to other options. Go to your spice cabinet and get out the spiciest chill or pepper blend you have. If you don't have anything go to Sam's club and buy the biggest thing of chilli seasoning or hot pepper seasoning you can find. If the dogs have messed things up get them just the way you want them and sprinkle generously all over the ground where they like to dig or lay. Make sure the dogs get a little on there nose or tongue so they know exactly what it smells like. After they investigate what it is they more than likely will not want anything to do with it. My dogs have not dug in these area's for 3 or 4 days now and they were digging things up every day.

Reply:This keeps the cats from leaving deposits in our flower bed and might work on dogs? Worth a try I'd say. We cut 2ft wide strips of chicken wire and layed them on the ground at the edge of the bed. The cats dont like the way the wire feels on their feet and wont walk on it,then they go next door! Sounds like you may have some big dogs ,so make yours wider,good luck
Reply:Go to Home Depot %26amp; buy some critter ritter, not harmful to animals %26amp; if that is not strong enough, buy the Deer Off, that should work.
