What would cause my 2.4Ghz wireless mouse to become erratic when my dog's head is nearby?

I have a black lab who, as long as I can recall, has a head which interrupts 2.4Ghz signals, most notably my wireless mouse. He doesn't need to be between the receiver and transmitter to cause interference. He simply needs to be _near_ either of the two, which rules out line of sight interference.

I thought I was crazy when the thought occurred to me, but i have ruled out every other cause, going so far as to changing rooms and even houses for testing, with the same results every time. If he is within 2-3 feet of either the receiver or the transmitter, inference abound.

It should also be noted, I have a collie mix who does not affect it at all, no matter the distance, only the lab. Unfortunately I don't have another labrador to test for comparison.

How does my lab do it?

  • Jul 3 2012: Could be they're crazy for each other.
    • Jul 3 2012: Thank you for the humor, though this is a serious question.
  • Jul 6 2012: Perhaps your dogs head resonates at a frequency that "traps" or interferes with the signal. I know that every persons head is tuned to a certain frequency regarding sound (you can find this out by humming different notes you'll feel it when you find it, mines F#). Maybe this can happen with other kind of frequency as well?
  • Jul 5 2012: Might he have one of those imbeddable spy-chips implanted in him?

    Jul 3 2012: Perhaps it could be your dog's collar belt? Or maybe your dog has had a dental implant? Alien abduction? Have you noticed any differences in your dog lately? Your dog may have been swapped for a robotic replica. If so, it may be possible to switch the bands, though it would require some disassembly,.

    Failing that, are you a 100 percent certain that your mouse isn't real?
    And have you ever considered taking a Voight-Kampff yourself, Mr. Webber?

    Jul 3 2012: There is likely some sort of electromagnetic interference coming from your dogs head I guess. You don't hear this question every day.
  • Jul 3 2012: Are you sure it is the dog's head, and not something on the dog, like his collar or tags?
    • Jul 3 2012: He rarely has a collar on, so that is ruled out. It is definitely his head, and if his rear end is nearby it does not happen. Only if his head is facing will it occur.

    Jul 2 2012: Maybe your lab has a chip in him? or maybe he ate something metal, its going to something very logical but original.
    • Jul 3 2012: I once had him checked for a chip (adopted him), but they could not find one. Of course, that doesn't mean he doesn't have one. I think this may be the most likely reason, as I recall they place them near the head (usually in the ear).

      I'll take him to a local shelter to have him checked again for a chip. As an aside, I'd hate for him to get lost and be returned to whoever a chip originally belonged to.

      Thanks for the insight.

        Jul 3 2012: Also see if your lab has any history of surgery, a metal plate or stint could potentially act as an alternate receiver

    Jul 2 2012: It may be that your dog's thought patterns are operating on the same frequency.
    Have you tried switching the bands?
    • Jul 3 2012: I don't think they make anything but a 2.4Ghz mouse, and this mouse doesn't vary within the 2.4Ghz channels.

      In my reading brainwaves operate in the low Hz range, so the likelihood of his brain being the interference is pretty slim (impossible?). It is still a wonder, though. On a practical note, it is quite annoying having my mouse stop working every time my dog wants attention, hah.
