How to Treat H3N2 Flu in Dogs

Medication: Dogs diagnosed with H3N2 flu often receive antibiotics to prevent or treat any secondary bacterial infections, such as pneumonia. Additionally, some dogs may be prescribed medications to widen their airways, reduce mucus thickness, or alleviate coughing.

Diet: Maintaining a balanced diet and ensuring proper hydration are crucial for bolstering a dog’s immune system, enabling it to effectively combat the H3N2 virus.

What to Expect at the Vet’s Office

Upon receiving a diagnosis of the flu for your dog, your veterinarian will assess whether hospitalization is necessary. Dogs severely impacted by the flu may require hospitalization for oxygen therapy, injectable antibiotics, and close monitoring of their respiratory function. Additionally, some dogs may be prescribed medications to widen their airways, reduce mucus thickness, or alleviate coughing.

Nebulization and chest thumping can also aid dogs in expelling thick secretions obstructing their airways. However, anti-viral medications like Tamiflu are generally not recommended, as they are most effective when administered early in the disease progression, which typically occurs before most dogs are brought to the veterinarian.

Once dogs with H3N2 are deemed stable enough to continue treatment at home, they can be discharged from the hospital.

What to Expect at Home

When managing H3N2 flu in dogs at home, it’s important to provide supportive care for their recovery. Encourage your dog to eat, drink, and rest adequately. If your dog is prescribed oral antibiotics, ensure adherence to the dosage instructions on the label, completing the entire course even if your dog seems to have recovered fully. Follow your veterinarian’s guidance regarding any additional prescribed medications.

To prevent the spread of the disease, dogs diagnosed with H3N2 flu should be kept isolated from other dogs for a duration of 14 days.

Questions to Ask Your Vet

When consulting your vet, consider asking:

  • If there are additional measures beyond isolation to reduce the risk of other dogs contracting H3N2, especially if you have multiple dogs.
  • Whether the available canine flu vaccine, originally designed for H3N8 flu viruses, might offer any protection against H3N2, given its unknown efficacy.
  • Whom to contact in case of an emergency occurring outside of your veterinarian’s regular business hours.

Possible Complications to Watch For

If you have any questions or concerns about your dog’s condition, don’t hesitate to discuss them with your veterinarian. Occasionally, dogs taking antibiotics may experience side effects such as loss of appetite, vomiting, or diarrhea.

It’s important to be aware that despite seeming to improve, a dog can experience setbacks. If your dog shows signs of becoming weaker, struggles to breathe, coughs more frequently, or develops a bluish tint to their mucous membranes, contact your veterinarian immediately.
