Is Thornit powder still being made and available anywhere you know of? All the old posts about it here are many years old. Until now, I've had a relative in Scotland order it there and then mail it over to me. The bottles last a long time, so I haven't had to order any for a few years. I have a dog owner neighbour with two adorable terriers with floppy ears and she mentioned that one of them gets ear infections, so I said I would send her a contact address. But now I find there's not much mention of Thornit powder online. The Amazon.ca site says it not available. Is it still available in the UK?
