Who Should Buy Ranitidine for Dogs

If you suspect your dog may be suffering from gastric ulcers, or acid reflux, you may wish to speak to your veterinarian about whether or not your dog could benefit from a course of ranitidine.

Gastric ulcers can be caused by a range of issues, but some of the most common include renal failure, the use of Non Steroidal Anti Inflammatory Drugs (NSAIDS), or corticosteroids. It can also be caused by stress.

In another use, ranitidine can also help food pass through the digestive tract more easily. This means its sometimes used to treat vomiting dogs, or those with delayed bowel movements.

If your dog is already taking certain other drugs, then treating with ranitidine may not be the best course of action. It can affect the efficiency of both ketoconazole, and itraconazole.

As with any drug, speak to your veterinarian before deciding to treat your dog with this medication.

If you’re concerned that your dog is stressed, but has yet to develop ulcers, you might like to consider using a natural supplement such as melatonin. Read our review of the best melatonin for dogs here.

Important Features to Consider

If you’re looking to purchase rantidine for your dog, there’s a few important features to be aware of. Here’s what to consider when selecting the best ranitidine for your dog:

  • Tablet strength. Ranitidine is available over the counter in tablet strengths of 75 mg, and 150 mg. The tablets containing 150 mg are often marketed as ‘maximum strength’. Your vet will be able to best advise which strength will suit your dog. Small, or elderly dogs may best suit the 75 mg tablet, as they will require a lower dose.
  • Packaging. Ranitidine is commonly available in bottles, blister packs, and individually wrapped tablets. If you intend to use ranitidine for your dog over a longer period of time, bottles are a great choice. They require less packaging, and are often better value for money. Blister packs are useful if your dog only requires a short dose, and you don’t want excess medication. If you take your dog travelling, or have mini first aid kits set up for them in your car, individually wrapped tablets are very useful.
  • Flavor. Some ranitidine tablets have a minty flavor that your dog may or may not like. And of course, some dogs are more willing to take pills than others, so choose an option that you can easily get your dog to take.

Frequently Asked Questions

What is ranitidine for dogs and how does it work?

Ranitidine is used to help treat gastric ulcers in dogs. It can also be used to prevent new ulcers from occurring. If your veterinarian has diagnosed your dog as suffering from ulcers of the stomach or intestines, as well as gastritis, they may suggest a course of ranitidine. It’s sometimes used to encourage gastric emptying, for example in vomiting dogs.

It works by preventing the stomach from producing excess acid. It does this by blocking the histamine H2. This histamine causes inflammation, swelling and stomach cramps. By reducing the levels of H2, and therefore the production of stomach acid, ranitidine lowers the pH of the stomach. This helps any existing ulcers to heal, and helps prevent new ulcers forming.


What’s the proper dosage of ranitidine for my dog?

Before treating your dog with ranitidine, first check with your veterinarian. They will be able to provide you with the correct dose for your dog.

As a general rule, the dosage will vary from 0.25 – 1 mg per pound of your dog’s weight. This should be given every 8 – 12 hours.

As an example, a Labrador weighing 60 pounds would require between 15 – 60 mg, depending on the dosage recommended by their veterinarian.


How long does ranitidine take to work in dogs?

There’s no clear answer to this, as it will depend on your dog’s individual response to the ranitidine. It will also depend which condition you’reusing the ranitidine to treat. Even if your dog does seem to have improved after taking this medication for a short time, it’s important to complete the full course, as recommended by your veterinarian.

Ranitidine should be given without food. So, if you gave it to your dog with their meal by mistake, expect it to take longer to work, or for the effectiveness to be reduced.


What are the side effects of ranitidine for dogs?

Ranitidine has few side effects, but can occasionally cause:

  • Nausea and vomiting
  • Mental confusion
  • Diarrhea
  • Agranulocytosis (low white blood cells
  • Irregular heartbeat
  • Muscle tremors
  • Rapid breathing

f you notice any of these symptoms in your dog after you’ve given them ranitidine, speak to your veterinarian immediately.

It should not be given to lactating dogs. Older dogs should be given this drug with caution, and they’re likely to need a lower dose.

If your dog has liver disease, kidney disease, or a heart rhythm abnormality, your veterinarian will advise whether or not your dog is a suitable candidate for treatment with this drug.
