I saw this on a canine list I am on. I thought those on the board who have a jumper might be interested. It is the most attractive solution I've seen. You can watch a video to see how it works. There may be some here who are familiar with this. It's the first I've seen or heard of it.

Addendum to this commercial advertisement in the REAL world:

Number of attempts before a coyote figures out how to get over this fence-topper with EASE: 1-3 <:-) But it might work for some of your average (here read "much dumber") DOGS...

It looks like a good idea, although you could make it yourself for a lot less money with a quick trip to the hardware store.

I am in agreement that this would work to keep a dog that jumps to get out from doing so. But I am still chuckling at the whole coyote thing. Maybe it is because I live in rural South Dakota where I have coyotes come through my property on a nightly basis and have had the same outdoor cats for 6 years now, and have never had them go near the dogs. Even when there is only one dog out at a time and one of the kennels is 50 yds from the house. Although there are accounts out there of female coyotes in heat luring out a male dog, mating with it and then turning around and killing it afterwards.(Not sure if it is true or not)
We have a mountain lion in the area also. He was treed and collared by GF & P here a couple months ago 3 mile from our house. 2 to 3 yr old male, feeding on raccoons and other various other game but no deer kills yet. He has been within a couple miles of the house. I do watch carefully for this critter but have a feeling that the cat can clear a 5 ft fence without even hitting the roller. I do have to say that the worst animal I have run into here is the badger. Was not that close to him (25 yds) but he made me fully aware he was there and not to get any closer and they are nasty animals to tangle with, and they can seriously injure or kill a dog in a heartbeat.
Maybe more "citified" coyotes go after dogs but my experience out here is that they are pretty spooky, even running when one dog barks. So for me this is just someone trying to make some cash. Just my two cents and opinion.

Don't know if it's concious (planned) behavior on the part of the coyote bitch, but it certainly has happened that dogs will go after her and then find themselves a ready-packed lunch for the rest of the pack. Unfortunately, around here, as so much development continues to dwindle habitat/resources, coyotes are getting "urbanized" to a frightening degree. We often hear a large pack right here close to my workplace, which is commercial/industrial zoned but with quite a few housing developments close by.

Becky,
After talking with our employees this morning who participate in every coyote hunt we have here, you are correct. The bitch lures the dog out, may or may not breed with the dog, and the others come in for the "kill". And there have also been instances where the bitch does it on her own.
I have a feeling the reason I do not have issues is because we are so rural and there is plenty of "prey" for them so they do not prey on domestic "pets".
I still do not think that a wild animal will come too close to a house and jump a fence and take a dog, unless normal prey is at a low or they are sick or injured and looking for "easy" prey. IMO only. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />

Carol, be glad you live where you do. I grew up backing to a forest preserve, and we often had coyotes in our driveway. Twice I ran outside to scare off 2 that were creeping into our yard to get my dog. The problem is that we've built townhomes everywhere they used to live. They have literally nowhere to go anymore, and have had to resort to group hunting large prey. Labs have been taken down while ON LEASH. We've had meetings to make newcomers aware when they tie their dogs out that they need to be on the lookout. We're turning into L.A. <img src="/ubbthreads/images/graemlins/mad.gif" alt="" /> I have a hard time looking at killing the coyotes as the solution. I honestly feel sorry for them.

A cool idea - just expensive. $26.00 for a 4 foot section. I thing you could use PVC pipe ans stick a steel rod throuigh it and make this yourself for a lot less.

I agree with ED, I thought the video was a bit funny. They teased that dog so crazy like <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />

My coytoes tend to go under the fences to get the sheep/lamb. Around here you never put any kind of a 'top' on your fence, you want it loose at the top so the coyotes cannot get a foot hold..same idea I suppose.

I was thinking that the plastic shower rod covers might work just as well on a wire at the top of a fence.
