I see these on Facebook all the time - promising the Earth.
Our problem is one of our dogs barks in the night. It's usually at foxes outside but annoying nonetheless. She quietens down if my husband sleeps on the sofa with her. We have a thunder shirt which we might try again but haven't tried changing her bed.
Her bed is just a duvet folded up. I wondered about one of those beds that she'd 'sink' into a bit more.
It's not a huge issue at all, and we've had plug ins, collars and stuff in the past for fireworks etc and I don't rate them.
Any recommendations for a good dog bed? She's a mongrel disguised as a beagle (rescue).
