Calculating the Proper Dose

Before administering Famotidine to your dog, it is crucial to calculate the correct dosage based on your dog’s weight. The recommended dosage is 0.25-0.5 mg per pound of body weight, given every 12 to 24 hours.

To calculate the correct dose, first, weigh your dog accurately. Then, multiply your dog’s weight in pounds by the recommended amount (0.25-0.5 mg). This will give you the appropriate dosage for your dog.

For example, if your dog weighs 20 pounds:

– For a dosage of 0.25 mg/lb: 20 lbs x 0.25 mg = 5 mg

– For a dosage of 0.5 mg/lb: 20 lbs x 0.5 mg = 10 mg

Always consult with your veterinarian before administering Famotidine to ensure the correct dosage and frequency for your dog’s specific condition.

Administering Famotidine

When administering Famotidine to your dog, it is important to follow the dosage recommendations provided by your veterinarian. Famotidine can be given with or without food, but it is generally recommended to administer it on an empty stomach for optimal absorption.

You can either give Famotidine directly to your dog by mouth or mix it with a small amount of food to make it more palatable. Be sure to provide your dog with plenty of water to ensure proper hydration and to help with the absorption of the medication.
