Hello. My dog has been sneezing A LOT the past few days. Is it possible she has allergies? Her nose is also running and dripping. She had diarrhea yesterday morning and a bloody soft serve poop in the evening but this morning her poop was back to normal. Do you know if dog can get the flu or is it something else?

Thanks for using Petco Pet Education Center, formerly Petcoach! Diarrhea can be observed with conditions such as colitis, gastroenteritis, dietary indiscretion, intestinal parasites, among many other possibilities. Sneezing can definitely be due to allergies and that is probably the most common reason. Some medications for allergies can be started for this to be used on an as needed basis. If her diarrhea or sneezing persist, I recommend that you have Irie evaluated by your veterinarian for further assessment and treatment. They may choose to check for parasites and to start medications for diarrhea and/or allergies depending on the results of needed. Good luck! Hoping for a speedy recovery!

    Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern! What you are describing may be a viral infection, in which case an antibiotic will not help with this type of infection. If there is a secondary bacterial infection along with a viral infection, then antibiotics can certainly help. If she has a viral infection or kennel cough, these typically are self limiting and will resolve within 7-10 days. If you are unable to afford a veterinary exam right now, I would monitor her for signs of worsening. If she begins to have difficulty breathing, you will need to get her in to be seen by a veterinarian for the most appropriate treatment recommendations. You can get a humidifier and also keep her in the bathroom with the hot water running so that the steam fills the room and she breathes it in. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further!

    Thanks for using Petco Pet Education Center, formerly Petcoach! Nose warmth/cold or dryness/wetness isn’t a sign of anything. Coughing and sneezing can be for numerous reasons. Without a physical exam and detailed history it is hard to say. If it was just a few times I wouldn’t be concerned. We sometimes cough and sneeze without a reason. If it’s frequent, I would recommend taking her to a vet to discuss. Heartworm is a possibility if she is not on monthly preventions. She could also have an upper respiratory infection, allergies, a bad tooth- the list is long. I would start with a vet exam and got from there. They can test her for heart worms while she’s there. Good luck and kisses Kenzie!

    It's rare that sneezing indicates any sort of issue. It would have to be fairly non-stop for me to be concerned, 10+ times an hour at least. As far as sneezing in her sleep, that's ok too, as long as it's not too frequent (again, many time an hour) If she were sneezing an abnormal amount, I would be concerned about a nasal foreign body, nasal mites, upper respiratory infection, or even congenital malformation of the nasal passageway. I don't think you need to do anything for this now. If you keep noticing it, keep a log to she how often she's sneezing, and take it with you to her next vaccine appointment to discuss it with her veterinarian. Best of luck and thanks for using Petco Pet Education Center, formerly Petcoach!
