How Much Benadryl Can a Dog Have in 12 Hours?
The safe dosage of Benadryl for dogs is typically 1 mg per pound of body weight every 8 hours. Therefore, how much Benadryl can a dog have in 12 hours depends on its weight, but never exceed 1 mg per pound within an 8-hour period.
Introduction: Benadryl for Dogs – A Common Remedy
Benadryl, also known generically as diphenhydramine, is a common antihistamine used in both human and veterinary medicine. Many dog owners turn to Benadryl to alleviate various symptoms, such as allergies, insect bites, and mild anxiety. While Benadryl is generally considered safe for dogs, it’s crucial to understand the correct dosage and potential risks before administering it. Knowing how much Benadryl can a dog have in 12 hours is essential to prevent overdosing. This article will explore the safe use of Benadryl for dogs, covering dosage guidelines, potential side effects, and important precautions.
Benefits of Benadryl for Dogs
Benadryl can be beneficial for dogs suffering from a range of conditions. It works by blocking histamine, a chemical released by the body during an allergic reaction. Here are some common uses:
- Allergy Relief: Benadryl can help alleviate symptoms of seasonal allergies, food allergies, and environmental allergies, such as itching, sneezing, and runny eyes.
- Insect Bites and Stings: It can reduce swelling and itching associated with insect bites and stings.
- Motion Sickness: Benadryl can help prevent motion sickness in dogs during car rides or other forms of travel.
- Mild Anxiety: In some cases, Benadryl can have a mild sedative effect, which can help calm anxious dogs during stressful situations, such as thunderstorms or fireworks.
Determining the Correct Benadryl Dosage
Calculating the correct dosage of Benadryl is critical for your dog’s safety. The standard dosage is 1 mg of Benadryl per pound of body weight, administered every 8 hours.
Here’s how to calculate the dosage:
- Weigh your dog accurately. Don’t estimate; use a scale.
- Multiply your dog’s weight in pounds by 1 mg. This will give you the total milligrams of Benadryl needed.
- Consider the concentration of the Benadryl product. Most over-the-counter Benadryl tablets contain 25 mg of diphenhydramine. Children’s liquid Benadryl typically contains 12.5 mg per 5 mL.
- Calculate the appropriate dose based on the concentration.
Example: A 50-pound dog needs 50 mg of Benadryl. If you’re using 25 mg tablets, you’ll give two tablets. If you’re using liquid Benadryl (12.5 mg/5 mL), you’ll give 20 mL (or 4 teaspoons).
Important Considerations:
- Always consult with your veterinarian before giving your dog Benadryl, especially if your dog has any underlying health conditions or is taking other medications.
- Start with the lowest effective dose and monitor your dog for any adverse reactions.
- Do not exceed the recommended dosage of 1 mg per pound every 8 hours. This relates directly to how much Benadryl can a dog have in 12 hours, as you should never double the dose to extend the interval between administrations.
Risks and Side Effects
While Benadryl is generally safe, it can cause side effects in some dogs. The most common side effect is drowsiness. Other potential side effects include:
- Dry mouth
- Increased heart rate
- Urinary retention
- Excitement (especially in some young dogs)
- Vomiting
- Diarrhea
In rare cases, Benadryl can cause more serious side effects, such as seizures or allergic reactions. If you notice any unusual symptoms after giving your dog Benadryl, contact your veterinarian immediately.
Precautions and Contraindications
Benadryl is not suitable for all dogs. Use caution and consult your veterinarian if your dog has any of the following conditions:
- Glaucoma
- Enlarged prostate
- Hyperthyroidism
- Cardiovascular disease
- Pregnancy or lactation
Also, Benadryl should be used with caution in dogs taking certain medications, such as MAO inhibitors. Always inform your veterinarian of all medications and supplements your dog is taking.
Differentiating Benadryl Products
It is very important to differentiate between different Benadryl products. Only use products containing diphenhydramine as the active ingredient. Avoid Benadryl products that contain decongestants like pseudoephedrine or phenylephrine, as these can be toxic to dogs. Always read the label carefully before giving your dog any medication.

If you suspect your dog has overdosed on Benadryl, contact your veterinarian or an animal poison control center immediately. Be prepared to provide information about your dog’s weight, the amount of Benadryl given, and any symptoms your dog is exhibiting.
Monitoring Your Dog After Administration
After giving your dog Benadryl, monitor them closely for any signs of side effects or adverse reactions. Ensure your dog has access to fresh water and a comfortable place to rest. If you notice any unusual symptoms, contact your veterinarian.
Alternative Remedies for Allergies and Anxiety
While Benadryl can be helpful for managing allergies and anxiety in dogs, it’s not always the best solution. There are several alternative remedies that may be more effective or have fewer side effects:
- For Allergies: Omega-3 fatty acid supplements, hypoallergenic diets, topical creams, and prescription medications like antihistamines and corticosteroids.
- For Anxiety: Behavior modification training, pheromone diffusers (such as Adaptil), calming treats, and prescription anti-anxiety medications.
Important Considerations
- Never give your dog human medications without consulting your veterinarian. Many human medications are toxic to dogs.
- Always follow your veterinarian’s instructions carefully.
- Keep all medications out of reach of children and pets.
