Not Veterinary Medical Advice
The information on this website is provided for general educational and informational purposes only.
It is not veterinary medical advice, a diagnosis, a treatment plan or a prescription, and it should not be used as a substitute for advice from a licensed veterinarian.
About the Dosage Calculator
The calculator provides mathematical reference calculations based on weight and published information. It does not evaluate whether diphenhydramine is appropriate for a particular dog.
The calculator cannot assess a dog's medical history, current medications, allergies, age, pregnancy status, underlying conditions or the exact product being considered.
A calculated number should therefore not be interpreted as an individualized veterinary prescription.
Product Information
Products sold under the same or similar brand names can have different active ingredients, strengths or formulations.
Always read the product label carefully. Combination cold, allergy or pain products may contain ingredients that are not appropriate for dogs.
If you are unsure about a product, ask a veterinarian before giving it to your dog.
Emergency Situations
Do not rely on this website for emergency treatment.
If a dog has difficulty breathing, collapses, develops rapidly worsening facial swelling, has seizures, or experiences another severe or rapidly worsening symptom, seek immediate veterinary assistance or contact an emergency veterinary clinic.
