My German Shepherd has green mucus, bloody nose. Can I use Benadryl?

Updated on September 23, 2025

Pet's info: Dog | German Shepherd | Male | unneutered | 9 years and 9 months old

I, quite some time ago, asked what I should do for my German Shepherd, Kane. He still has a constant flow of mucus, very slightly green and from time to time he either sneezes or blows his nose. This produces several small to large(2 inches long) masses of blood and mucus. I can't afford a Vet but when I take him out he is lively, ears up, great spirits. What can I use to dry his nasal passage like non drowsey Benydryl & what strength? Thank you, Mickey Michael D Beskin

It sounds like he has an active infection that is draining so you don't want to use any over the counter products that are designed to stop that drainage, this will undoubtedly make him much sicker. You want to find out the cause of his rhinitis (inflamed nasal passage) and upper respiratory infection. Unfortunately this isn't cut an dry and at the very least requires an exam through your veterinarian. You won't be able to help Kane with at home remedies or over the counter products.
I would first start with a short course antibiotic though the vet to see if this clears things up. If this doesn't work, then a bacterial culture can be done to see what antibiotic this infection is sensitive to, to make sure we are on the right track. Also a skull radiograph can be considered to look for underlying masses (considering his age), growths or any abnormalities in the nasal passage itself. Here are some financial resources, if needed. I hope you find some answers soon and I hope that Kane makes a full and speedy recovery. Best of luck.

    Benadryl isn't used in dogs to treat nasal congestion, so I would not give it to Bruiser. The only medications available to treat nasal congestion in dogs are prescribed by a vet, and I would have him seen by a vet to get medications prescribed. You can try using a humidifier or bringing him 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 congestion.

My old dog has itchy nose, sneezing, clear discharge. What to do?
Handsome boy! He may have allergies from spring pollen or a mild cold. You can give Benadryl to reduce the nasal discharge and itching. There is a section on this website with information and dosages of common over the counter medications that are safe for dogs. if he stops eating, the discharge gets green or he's very lethargic then I would recommend a veterinary exam. Usually this will get better in a week or so without treatment. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Bo.

My rescue dog has a sinus infection. Will it heal naturally?
You can try some Benadryl twice a day to see if this helps. See link below. You can also put her in a small bathroom with a hot steamy shower going to allow the steam to help break up the mucus. If it isn't improving, then I would have your vet take a look at her. Unfortunately, a lot of dog end up needing antibiotics to help get rid of these upper respiratory infections. I hope this helps! https://www.petcoach.co/canigive/dog/benadryl/#!

My dog has a snotty nose. Is it serious, or will it clear up?
I recommend purchasing a basket muzzle either from amazon or from your local pet store and scheduling an appointment with your vet. That much thick nasal discharge definitely indicates either a bacterial or viral respiratory infection that can possibly lead to pneumonia (expensive/difficult to treat and possibly life threatening) if not treated early. Your vet may write a script for Xanax and dispense trazadone to be given prior to the appointment. Good luck! Keno is a good looking shepherd!

My old dog has green snot, tail down, and weird breathing. What's wrong?
Poor Spike. With his age, there could be several different things going on and the tail and green nasal discharge could be unrelated. As far as the tail, this could just be indicating that he doesn't feel well or it could be something going on with his tail muscles or anal glands. The nasal discharge is quite concerning. This could be indicative of a pneumonia, bacterial infection, severe upper respiratory infection, viral infection, fungal infection, or even cancer. You could try Benadryl twice a day (see link below), a humidifier in his sleeping area, and even holding him in a small bathroom with a hot steamy shower going to help break up the mucus. With his age though, I would strongly recommend to have him seen by your vet. Your vet can do blood work and x-rays if needed and get him started on the proper meds to help him feel better before he gets worse. https://www.petcoach.co/canigive/dog/benadryl/#!

Vet Q & A
Why is my senior dog sneezing with a bloody nose and dry paws?
Poor girl! It sounds like she has some allergies! You can try giving her 1/2 tablet of a 25mg Benadryl to see if this helps but with her having blood from her nose this could be something more serious like a fungal infection or a tumor in the nose so I would have your vet do an exam on her and maybe some skull X-rays. Also if her paws are dry looking she could have a bacterial or yeast infection between her toes or Paw pads. Your vet will be able to look at her pads again and see if she needs medicine for that as well. your vet will also be able to put her on a stronger allergy medicine if needed. I hope this helps and she starts to feel better soon.

My new puppy has a runny nose and is itchy. Can I give her Benadryl?
Hello. Benadryl will not help the runny nose in your puppy as she may have a mild upper respiratory infection. If she is eating & drinking well, playful & active, this will probably resolve on its own. The itchy skin might be from fleas, or mites. Make sure you are treating her with an age appropriate flea product & if she continues to itch, I would dip her once a week in a Lime Sulfur product that you can purchase on-line or at most Tractor Supply stores. This would be much better than Benadryl. If the nasal discharge turns thick or your puppy seems unwell, please see your veterinarian as soon as possible.

German Shepherd yelping, nasal drip, changed bark. Ear infection?
If her ears are bothering her, there is certainly a problem with them so the ointment should make a difference. Antibiotics will help if there is concurrent bacterial infection and prednisolone has an anti inflammatory effect. So you have medications that should help against a few symptoms and conditions. Perhaps she will feel better today. The other thing I would keep in mind is if she could have inhaled something like a grass seed. These are very commmon where I live at this time of the year. So if she seems to be getting better continue with treatment, if she is getting worse or not improving have her reassessed.
