My dog has been doing this a few times, weird sneezing/retching sound, i've done research online and seen a few videos and that is what he has cause he's all happy, walking and like usual when he does it. I was wondering if someone's dachsund does the same once in a while. Could be cat hair that gets stuck in his nose. anybody has an idea how to clean/check if he has something stuck up there? They have such long noses you never know.
