Collar rot - cleanup & treatment?
Looking after a friend's Newfie and just noticed today that his collar has been WAY TOO tight. For how long, I dunno, I've only had him a few days and the collar is as it arrived.
He's developed a lump or blister that started to weap that real nasty smelling puss. No blood, no open sore. Just a bit of puss.
I've had dogs get this before - ones we had to keep tied - and usually cleared up after a couple days with no collar and regular cleaning.
Any other / better suggestions?
