We had a REALLY long thunderstorm last night. For the last year or so Max barks at thunder. It has definitely been getting worse lately. He doesn't show any other signs of stress (drooling, panting etc.) and he will stop his barking long enough to work for treats however that really isn't practical at 3:00 a.m.
I have tried a thundershirt, classical music - and a combination. I have tried a (little) bit of classical conditioning by playing storm sounds at low volume but he seems to be able to tell the difference. Last night he woke us up barking before we could even here the thunder.
Anybody have any good ideas? I was hoping not to have to go the drug route but I'm fresh out of ideas.
