I’m so interested to hear about Milo’s laser therapy. It’s a treatment that I don’t know much about, so I’ll surely be interested to know if it ends up helping him. As far as the sleep disruption, the little that I’ve read about collapsed tracheal issues makes it sound as though that problem is noticed more often when a dog is awake and/or excited. Since the grunting happens when Milo is asleep, I wonder if he could be suffering from an issue similar to sleep apnea in humans. I’m embarrassed to admit that I snore myself, and my husband tells me that sometimes I wake myself up with a snore and I know that some people with apnea wake themselves up snorting and gasping. I’ve recently considered being tested for apnea, and that’s why the issue popped into my mind when you described Milo’s behavior. I don’t think it’s common in dogs, but apperntly it can sometimes happen. If it’s even a possibility, your vet may want to examine his nose and throat a bit more carefully the next time he’s checked. Sorry I don’t know more, but it’s just a thought.
