I’ve heard the same thing from a dog owner before. Animals do seem to sense things we can’t.
Pets are great, especially when treated well and taken care of. Dogs, Cats, -doesn’t matter. I have read about dogs that selflessly throw themselves at anyone and anything for their families to protect them no matter the cost, and I know personally of one couple with five VERY large cats that are very protective of their people family. They won’t even let some neighbors get close to the door without lots of hissing and tail-thrashing that lets everyone know that those strangers are NOT welcome, lol!
