There are cyclones in the Pacific, Bavi, Nathan and Pam (Pam was the one that killed both: Fawndog's low BP end and Jimmy the RBI dog's initial dip in immunity) .
There's really no reason for dogs in India to die of gangrene, a drop in immunity and severe sepsis, if there's a storm several thousand miles away unless there's a different connection, maybe a deep ocean connection or an atmospheric link between these storms. I'm sure something links up and the animals energy field responds as if under attack with a systemic inflammation.
Here's someone talking of one of those connections called the MJO pattern or event that occurred on the 16th of March 2015, recording the highest MJO index mark in history. Nothing less could have killed poor Jimmy who was one helluva survivor.
