Hi Angus,
Like Eva said, sorry you had to find us, but you found a good source of info. My dog was diagnosed in July so I'm still learning about this sickness. My vets said to watch Harley for any respiratory distress in the first week or 2 of starting Itra treatments. What's growing in the lungs starts to die off & it can take a while for the body to absorb the dead fungal matter. As long as your pup's up to going out in the kennel, the sunshine & fresh air is probably good for his soul, just like us people!
Itra seems to work great, but then Harley has not been nearly as sick as some of the other members dogs. He'd been picking at his food & lethargic for a few days, started Itra on a Monday, & by that Friday was back to normal, eating like a pig! Of course then his diet included bacon grease, so what's not for a dog to love about that.
Keep in touch & don't be afraid to ask questions. No 2 cases are exactly the same & you may come up with something that hasn't been touched on before & be useful to someone else. There's a bunch of folks who read posts regularly & we're all pulling for both you & your dog.
