True. There are GPS devices for dogs although I don't think they are used in a similar manner as microchips. And even if they were, it's never been reported Seven had a GPS collar device. Never. The device he had has always been referred to as a chip/microchip. And those are not tracking devices despite multiple reports saying JW used the chip to "track" the dog to the H&F over a week after HP was last seen at the game.
GPS collar devices tend to be heavy and tend to need very frequent battery replacements. Some need the rechargeable batteries rotated out
daily. Some have batteries that last a couple of days. But
all are very heavy battery-users. From what's been reported, JW didn't try to find Seven until after he got HP's phone from her house on the 21st. Then he said he waited until the 25th, 8 days after HP and the dog were last seen to listen to messages to see if there was one about Seven. There just no evidence there was a GPS device. But if there had been, the battery would have been long dead 8 days after HP was last seen. And how would a GPS device lead to a call to HP from the dog-finders? Or are we assuming Seven had a chip AND a GPS device?
Also, the range of GPS devices is not unlimited. Some are advertised to have long ranges--- and from what I can see, that means around 9 miles. The H&F is more than 9 miles from HP's home. (Usually the devices are set up with "safe zones" like one's home and backyard. An alarm sounds or a text msg is sent whenever the dog leaves those areas.)
What has been reported about finding the dog doesn't make any sense to me. As previously mentioned, it makes no sense to say JW "tracked" the dog by his chip. That couldn't happen.
It was also reported when JW said when he remembered Seven had a chip he found the relevant info and called the chip co (sometime around the 21st.) And at that time, 4 days after HP went missing, the company said the dog had been found by somebody, somewhere. That makes no sense. Reading the chip by scanner is a passive process and would not give any feedback to the company. Chips don't need batteries as they are briefly activated by the scanning device only long enough to provide a unique ID number. That number is then manually entered into the company's computerized database to get owner contact info. Maybe when the number is plugged into the database, a record is created? (That wouldn't prove the dog had been found but would prove the number had been entered.) But even after JW said the company claimed the dog had been found by somebody somewhere, and so he knew a dog finder would likely call HP, and he knew
or certainly should have known a key to finding HP was finding the dog, JW didn't try to listen to messages on HP's phone for FOUR more days? Rather an incurious fellow, wasn't he?
And where did the dog-finder have Seven scanned on a Sunday night? (Reportedly the first msg was left on HP's phone that Sunday.) Was Seven also wearing an ID tag and that's how the finders got HP's number? If so, how/why did the chip company think the dog was found? I know if I found a dog with an ID tag on a collar, I'd call the number on the ID tag. If I didn't hear back after leaving messages, I certainly would not load the dog into my car after few days and drive him somewhere to be scanned for a chip. Even if the dog HAD a chip, why would I care? If the dog had an ID tag on his collar, I'd assume that info was up to date, or at least as up to date as any microchip database as those are notoriously wrong. People forget to update those. Out of sight, out of mind. And many chips that have been inserted into animals are never registered to any owner. (One study found only 58% of inserted chips were actually registered.

So none of this makes sense to me.
The only way it makes sense is to assume JW isn't telling the truth about when and how the dog was found. He could have been asked by LE not to discuss how he found the dog. And I guess LE might have asked him to tell this made up a story about finding the dog (although I suspect he did that on his own as it's such a ridiculous story.) Or he could have his own reasons for not telling the truth about finding the dog.
