Dog Antihistamine Dose Guidelines

Antihistamines are often used to alleviate allergy symptoms in dogs. However, it’s crucial to administer the correct dosage to ensure your pet’s safety and effectiveness. Here’s a guide to help you determine the appropriate dosage for different antihistamines commonly used for dogs:

   • Estimated Dose: 2 mg/kg (milligrams per kilogram) twice daily

2. Telfast (fexofenadine):

   • Estimated Dose: 5-10 mg/kg once daily
   • Additional Information: Fexofenadine can be less sedating than some other antihistamines. Consult your vet before use, as the dosage may vary based on your dog’s needs.

3. Claratyne (loratadine):

   • Estimated Dose: 5-20 mg once daily
   • Additional Information: Loratadine is typically less sedating and may be used for long-term allergy management. Consult your veterinarian for the most suitable dose for your dog.

   • Additional Information: Cetirizine is generally well-tolerated by dogs. However, the dose can vary, so it’s essential to consult with your vet for precise instructions.

It’s crucial to remember that the right dosage for your dog depends on their weight, specific condition, and the guidance of your veterinarian. Self-medicating your dog without professional advice can be harmful, so always seek veterinary consultation before administering any medication. The well-being of your furry friend is a top priority.
