Yes, as far as OP title question... imho and experiences, anyway.
The definition of "paranormal" is important, though.. .maybe "currently unknown" is better.
I've had numerous experiences where dogs have reacted to unseen/heard things in specific residences... and before someone brings up infrasound or
subtle smells/cues , it wasn't like that in a few cases...
one residence had an unseen presence actually playing fetch with the dog ... the thrower was always outside, just out of view in the backyard, always
throwing into the house... always from an arc that placed them about four feet from the doorway and letting the ball go at about 3 feet in the air
with a broad arc that almost brushed the ceiling.
No experimentation could explain that one.. . there was a high fence around the yard and we would dash out within half a second to find no visible
person... plus no photographs taken in that house would show anything but a grey cloud, unless that dog was photographed, and then only that dog would
come out in perfect detail.
Also, there and in other "haunted" residences where formerly placid dogs would alert to a certain spot and follow some invisible something as it moved
through the residence, to the point of losing it at a wall and then picking it up again as it emerged from the other side.
This happened literally a hundred times in the space of 6 months in that place, accompanied by knocks, little blurs in the peripheral, strange moods
and feelings, both emotional and physical, strange light phenomena, objects moving when not looking at them, and rarely while one was looking right at
it with others present, etc.,etc.
So... yeah, they can sense things we can't, it seems. The huge question is then what exactly they're seeing... and "spirits" though an ill defined
word, fits.
