We've had Maui for 2.5 months and he's had 3 sneezing bouts so far. I've taken him in every time for it and every time he's had an upper respitory infection.
The 1st time he was sneezing & he'd make a weird hacking kind of noise, the 2nd time he just sneezed a lot, and then this last time his third eyelids started showing then a day later he started sneezing!
My vet is having me give him the Lycosine to help boost his immune system now.
How long has he been sneezing??
I think you should have him checked out- better safe than sorry! Your guy may not be feeling very well & he doesn't have many ways to tell you, so we have to be extra watchful.
