My puppy is sneezing, tired, and cranky. Could it be allergies?

Updated On September 23rd, 2025

Pet's info: Dog | Pembroke Welsh Corgi | Male | neutered | 4 months and 14 days old | 33 lbs

My puppy has been sneezing very often for the past 3 days. Doesn't matter if we're inside or outside. His appetite hasn't changed, but is a little more tired and cranky. He is also teething though, can see he has lost about 4 teeth in last 2 weeks. Could it be an allergy? We haven't changed food or treats in the past 3 days...

Hi there. Sneezing could be caused by allergies, or an upper respiratory infection. If he's acting fairly normal otherwise (eating and drinking fine, active, etc.) you could opt to monitor him for now and see how things go for the next few days. The problem may resolve on its own, similar to when we get a minor cold or allergy flare-up. If there is no improvement in the next 2-3 days, or if your pup develops other symptoms such as coughing, thick green or yellow nasal discharge, or begins acting very lethargic or not eating, then I would recommend having him seen by a veterinarian for treatment.

    No, this isn't normal and this can be sign of a respiratory infection or allergies. It would be best for Oreo to see a vet. The vet can diagnose what is causing her symptoms so she can be treated. I would have her seen by a vet this weekend if they are open for normal business hours; if not, I would take her in on Monday. Make sure she keeps eating and drinking, and stays warm. If she appears congested, you can try using a humidifier or bringing her into the bathroom with the door closed while you take a hot shower - the steam and humidity help to break up congestion and temporarily relieve symptoms associated with respiratory infections. I hope this helps!

    Ifs he is eating and drinking normally and still playful, then you can try the steam from a hot shower to help break some mucous up and see if that helps. If it does not get better or her appetite is decreased then I would have your vet examine her to see if she has a respiratory infection or if it is allergy induced.

We just got our 10 week old puppy 2 weeks ago. Since we got him, he's been sneezing and has snot coming out of his nose. Sometimes it's making him breath oddly. Also, he's biting/scratching/licking his legs a lot. Is this allergies?
He may have an upper respiratory infection. Since this has been going on for so long, I suggest getting him in to see your vet for an exam. He may need medication in order to help him shake his cold. The itching could be any number of things, from allergies to food or something in the environment, to fleas. Your vet can check this out at the same time as the sneezing and can give you a better idea of what is going on and how best to treat them both.

Dusty is a very handsome boy! Yes, it is possible that he could have allergies or a respiratory infection, but without seeing him in person, I can't say for certain. I would have him seen by a vet for this on Monday if he's still sneezing. Until then, only take him out long enough to go potty, keep him indoors and warm, make sure he keeps eating, offering him gently warmed wet food if it appears he's going off his food. Also make sure he's drinking plenty of water, and rest him. I hope this helps!

Hello, sorry to hear about Brooklyn. She could indeed have allergies despite being on allergy medications. Having sneezing is mostly consistent with some upper respiratory tract disease such as allergies or an upper respiratory tract infection. She could additionally have some other form of respiratory infection (pneumonia or bronchitis). You should see signs of coughing and nasal discharge with this. If you note persistent signs from Brooklyn, then she should be evaluated by her veterinarian. Hope this helps and best of luck.

My puppy’s nose is runny and he’s constantly sniffling. I haven’t had him a week yet and the first day I had him, he would blow snot bubbles from his nose. He also sneezes a lot. Besides that, he doesn’t seem to be showing any other health issues. Co
Allergies are not common in a puppy but they can occur. More common would be an infection. I recommend to have him examined by a veterinarian. New pets should generally have an exam soon after they are adopted to test for worms which could spread to humans and have an over all health assessment. I hope this helps.

She may have a mild respiratory infection or possibly an allergy to something, especially if there is something new in her environment. Monitor her and if the sneezing or coughing persists or becomes worse than have your vet take a look at her to determine if treatment is needed.

Poor Julian! Dogs can get respiratory illnesses and allergies, both of which can cause sneezing, coughing, and discharge like you've seen. In the case of infections, the discharge may become cloudy or yellow/green, whereas allergies tend to stay clear. In either case, since this has been ongoing a few days, it's a good idea to bring Julian into your vet. They can provide allergy medications or other treatments as needed depending on the cause. If you notice him worsening, the discharge changing color, fever, or changes in behavior or appetite, that's a sign that he needs to be seen sooner. Until then, keeping his eyes and nose clear with a clean washcloth can help keep him comfortable and prevent any debris from getting stuck and crusting his nostrils or eyes shut. Keeping him eating and drinking and in an area free of dust and dander can also help.

It has been a couple of days that my dog has been sneezing periodically. Just recently his nose has gotten warm along with his ear. Could he be sick? His appetite hasn't changed
Periodic sneezing can just be a sign of allergic rhinitis, especially if he is otherwise eating well and behavior hasn't changed. Contact your vet to see if there are some antihistamines that can be tried for now, then continue to monitor him to see if the sneezing improves over the next few days. If he does develop any nasal discharge or eye discharge at any point, then a vet visit is definitely recommended. I hope that Diego feels better soon! Best wishes and take care.

Sneezing can be a sign of an upper respiratory infection, particularly if the nasal discharge looks thick yellow or green. If the discharge is clear, it could also be a sign of allergies or just nasal irritation. If the discharge is colored I would recommend seeing your veterinarian once they are open. If Bailey's appetite becomes decreased or she begins coughing you may want to consider seeing an emergency veterinarian.

Cruz sneezed every now and then but has shown no other signs of a URI . Could it be an allergen??
It's possible. Dust from bedding, ammonia from bedding that needs to be cleaned more frequently and even household allergens can cause sneezing. if you're seeing clear nasal discharge, red or itchy eyes this can also indicate a possible allergy. However, if the discharge is green or yellow, Cruz has raspy breathing, or he is lethargic, feverish, or loses his appetite, those signs point to a URI being more likely and should be checked out by a vet.
