Tracking Domestic Animals?
Solo-Malee asks: "My sister has a blind hunting dog (yes really) and will soon be moving to the wilderness area of Sweden. She is really worried that her dog will run off after the first elk that it sees never to be seen again (since he's already run off numerous times already). Are Slashdot readers aware of any practical inexpensive tracking system that can be applied to domestic animals?"
How does he see the elk? Does he need a seeing-eye human?
Tracking, unfortunately, won't keep your dog from getting hit by a car. It also won't keep you legal if unleashed dogs are against the law (which is quite common in the US, anyway). I would consider an "invisible fence" which is basically an RF proximity sensor on a collar that shocks the dog if it gets too close. They seem to be quite effective and can give the dog a very large area in which to roam. In particular, it makes sense in situations where a backyard-type fence is impractical (such as on a farm), but a border is well-defined by a cattle fence or some such. Here's the cursory google search: http://www.google.com/search?hl=en&q=dog+invisible +fence&btnG=Google+Search

If the dog can't run off, he can't run off and get lost. I'm not trying to be a dick about this, but unless chaining a dog is illegal in her area, your sister should consider the obvious option. Occam's razor, and all. So long as food and water bowls are within easy reach, and kept in the same place, the dog shouldn't have a problem.

elk is Cervus elaphus or wapiti or some such beast.

I've had the same problem playing NetHack. The best option is to use a magic whistle (a blessed eucalyptus leaf will work in a pinch).
If a magic whistle isn't available, then a leash can work well. Failing that, be sure to feed your pet regularly and always carry some tripe. The dog, attracted by the smell, will follow you more closely.

My sister has a blind hunting dog ... She is really worried that her dog will run off after the first elk that it sees
Her worries are unfounded.

Ok, now let's ask about a tracking device for my...um...Cat, yes...cat...I want to track my cat in case it runs off chasing Elk.
Obviously, I will need a lighter tracking device than discussed for my dog. It needs to be light enough so my girlfriend..oops..I mean Cat, cannot tell that it is attached to their person...oops...I mean fur.
Also, I want to purchase this device with cash. That's so the police...oops...I mean the Cat Cabal cannot track me down.
