Senior Dog Runny Nose Care Guide
Does your senior dog have a runny nose? Find out which nasal sprays are safe, how to use them, and when to visit the vet. This guide focuses on safety and real causes.
Older dogs often get nasal discharge due to congestion, dental disease, chronic rhinitis, fungal infections, or nasal tumors. Here, you’ll learn safe home care methods using sterile saline and when professional treatment is needed.
Senior dogs are more likely to have ongoing nasal discharge caused by:
- Chronic rhinitis or sinusitis
- Dental disease reaching the nasal passages
- Fungal infections (such as aspergillosis)
- Nasal tumors
Clear, watery discharge usually comes from irritation or allergies. Thick, colored, or one-sided discharge often requires veterinary care.
If your dog has facial swelling, bad breath, or breathing problems, contact your vet immediately.
Sterile isotonic saline (0.9%) is the safest option for at-home relief.
It helps by:
- Moisturizing nasal passages
- Thinning mucus
- Removing allergens and debris
Saline offers short-term support but does not cure infections or structural problems.
Use it one to three times daily and stop if symptoms worsen.
Never use human cold medicines or medicated nasal sprays.
Ingredients such as phenylephrine, pseudoephedrine, and oxymetazoline can be toxic to dogs.
Avoid products containing xylitol or essential oils.
If exposure occurs, contact your veterinarian or Pet Poison Helpline immediately.
- Warm the saline bottle in your hands or warm water.
- Gently restrain your dog and keep the head level.
- Aim at the nostril opening without inserting deeply.
- Apply 1–2 sprays or drops per nostril.
- Allow sneezing and wipe away excess fluid.
- Start once daily. Increase only if well tolerated.
- Visit the vet if symptoms last over 2–3 days.

Vets often use pediatric saline brands for dogs because they are sterile and preservative-free. Veterinary-grade saline is used for formal nasal flushes in clinics. Do not attempt large-volume nasal flushing at home without veterinary guidance.
Contact your vet if you notice:
- One-sided discharge, thick yellow/green mucus, blood, or facial swelling
- Appetite loss, fever, or significant lethargy
- Ongoing symptoms after several days of saline use
These signs usually mean your vet will need to perform tests such as a dental exam, nasal swab or culture, rhinoscopy, or CT imaging. Treatment may include antibiotics, antifungals, or surgery.
Q: Is saline safe for daily use on senior dogs?
A: Yes, sterile, preservative-free saline is safe for short-term daily use. Frequent need suggests an underlying problem.
Q: Can I use human medicated nasal sprays?
A: No. Medicated sprays and decongestants can be toxic to pets. Contact your vet if unsure.
Q: My senior dog has blood in the nose — what should I do?
A: Take your dog to the vet as soon as possible. Bloody discharge can indicate serious problems.
For mild, clear nasal discharge, sterile isotonic saline spray or warmed saline drops are the safest first step.
Watch for warning signs and contact your vet if symptoms worsen, become colored, bloody, or do not improve.
Serious conditions such as fungal disease, tumors, or dental infections require professional testing and prescription treatment.
