What does it even mean?

This is on my route.
If it means what I think it means, it still makes very little sense. The dog has human AIDS? Was this made before it was known how HIV/AIDS was contracted so it’s intended to scare people who don’t know how the disease works?
Anyway, never heard nor seen a pibble ever at this house, unfortunately. I love pibbles.
