My 13 year old beagle has recently developed a kind of cough that ends in gagging. It will happen once or twice during the evening; he’ll suddenly get up and start hacking. It only lasts a few seconds, nothing ever comes up, and then he’s done and shakes his head and goes back to napping. He hasn’t been around any other dogs, so I doubt it’s kennel cough, and he has no other symptoms. No loss of appetite, and he has great energy for his age. No weight loss either. It’s not reverse sneezing, although he sometimes does that too. Does anyone have experience with this? If he had any other symptoms I’d take him to the vet immediately but he seems otherwise totally fine and happy. I’d appreciate any feedback!
