"Invisible fence" for dogs

We've lost a couple of neighborhood dogs to coyotes - let out to pee unrestrained and done-in in plain view. A lot of cats have evaporated as well though there are a couple of outdoor cats in the area who seem to have found a way. There has been a major reduction in coyote population over the past 2-3 years. Mange may be one factor but there's been some organized hunting as well (open season from Columbus Day through mid-March). A couple of years back there was a pack that apparently attempted to take some yarded-up deer behind my house. Deer are not defenseless - my neighbor found 2 dead coyotes (stomped) behind his house the next day.

A real fence can discourage the coyote. And I'm not at all sure that coyotes are always faster than dogs. Speed depends on age and condition, for one thing.

I agree that a "real" fence can "discourage" a coyote. Make it a good one, not one that will just discourage your own pet.

Have you ever encountered an old coyote? Coyotes are in better condition than domesticated pets, even old ones. You should know why.

Ever heard the story of a coyote with 3 legs running all day after chewing its leg off to get out of a trap?

Have you been in remote areas where you could observe them? I have.

Even if they cannot outrun a fast dog, they can always outlast them.

Try this:

It is in your area, maybe.

Friend of yours? ;)

And breed. I am sure that a greyhound would give a coyote a run for his hunger.

All that cardboard based dog chow? The presence of smelly humans?

...and whatever other food is available. "You don't have to be faster than the bear..."

His friend is suuuurrreee ugly. ...a real dog!

I'm not a dog person myself, so (as they say) I don't have a dog in this fight. ;)

I do think it's a shame if some animal gets chewed up because its owner didn't care, though.

I like dogs but they take too much work so we have a couple of cats (one just climbed up on my feet). I agree, whatever the pet, their welfare becomes your responsibility, once they're taken into your home.

BTW, coyotes aren't the only predator that feeds on pets. Owls will take cats and small dogs, too. A friend had an hawk grab his Fifi from his back yard (but released it), while he was watching.

I'm not one who objects to hunting coaters with Greyhounds, though. I could deal with fewer coyotes around here, too.

loop equals the current going through the surface enclosed by that loop. I'm aware that that is not the whole story, but it's near enough for a dog fence. It may seem odd to some, but the presence of magnetic materials does not change that. The steel pipe does not shield the field.

Jeroen Belleman

Right. I'll see if I can rig up something and show the results. We'll see if what I think I know is true. ;-)

Jeroen Belleman

You are confused. A piece of metal pipe with unconnected ends is not a shorted turn for the current running through a wire running through it. It would be if the wire had been enclosed in the pipe over its full length and if the pipe ends were connected together. (We're talking LF AC, of course.)

Jeroen Belleman

Yes, that works.

Jeroen Belleman

I don't understand the question. Please clarify.

I agree with you. Just as I believe that not giving them heart-worm preventative should be criminal. If you can't afford it for your dog, then find him a home that can.

Prison for not vaccinating a dog? What about the human suffering that entails?

Some dog people need to get more of a life.

Right, if it's like the heart rate monitors, it would be around 5KHz, the range is small like 3 feet, and the signal is AM/PAM encoded for the dog collar receiver...false activation rate is near zero.
