Build an Ark, Noah......

Older dogs can become noise sensitive as they age.

I am wondering if the electrical charge produced by storms has anything to do with it?  But, it's the noise that freaked mine out. He'd start crawling up your behind the second he heard a clap of thunder miles away even. Maybe it's both?
I see those snuggy type jacket things now for dogs afraid of thunder. I can't for the life of me see how that works though. I would hold mine to comfort him and he'd be wiggling and crawling and clawing...that secure pressure that these jacket things seem to claim is what calms them, would NOT work on this dog!
I'm crackin' up about your Mastiff trying to crawl inside the dryer and not fitting, Liz! OMG lol I am just picturing that whole thing! lol  I am seeing pooh bear getting stuck in the honey tree..butt sticking out...is that what he looked like? lol  Loved your choice of words with "An insignificant other other of mine"!!!!  HA HA HA. You so funny woman!

I think dogs are sensitive to barometric changes.

I think it was Cloud the story of a wild Mustang that had in it that a lot of wild horses get hit by lightning. I know pigs and cows get nailed, I saw a hog take a direct hit in a thunderstorm. One of the freakiest things I ever saw in my life was that big pig just standing there after it got lit up. For about 5 minutes it stood there tense and then it just fell over legs out stretched stiff. Like a toy pig in a farm toy set. Yikes. My little brother was there and after it fell over he says real loud....BACON.

You can use those thunder jackets that the cow chutes designer lady sells, those work real good.

My dog has a Thundershirt.  He loves it but he still runs around like a maniac barking at the storm. Lol.
