How Much Aspirin Can I Give My 70 Lb Dog?

Dogs can get really sick from too much Aspirin. If you’re giving your dog Aspirin, you want to make sure they don’t overdose.

To figure out how much Aspirin to give your dog, you need to calculate their body mass index (BMI). The BMI tells you whether or not your dog is overweight. In this article, we’ll look at how much aspirin to give a 70 lb dog, and how to calculate their body mass index.

We’ll also talk about how frequently it’s safe to give your dog a dose of aspirin, and everything else you need to know on the subject.

How to Calculate Your Dog’s Body Mass Index (BMI)

The first thing you need to do when calculating how much Aspirin you should be giving your dog is to find out what their body mass index (or BMI) is. This will tell you if your dog is underweight, normal weight, overweight, or obese.

A healthy dog has a body mass index between 18.5 and 24.9. A pet that weighs more than 25 pounds but less than 40 pounds is considered overweight.

If your dog is over 40 pounds, then they’re considered obese.

Calculating your dog’s body mass:

You can use an online calculator to quickly find out your dog’s body mass. These are available for dogs weighing up to 100 lbs. You can use these calculators to determine your dog’s body mass by measuring them in inches.

You can measure your dog using any tape measure, but you’ll have to take into account the length of their legs and chest. 

To find out how long your dog’s leg is, wrap the tape around the leg just above the paw. Then, wrap another piece of tape around the leg just below the paw. Now, add those two lengths together.

Next, wrap the tape around your dog’s chest just above the elbow. Add the two lengths together. Finally, multiply the sum of the three measurements by 4.2 to arrive at your dog’s body mass in pounds.

For example, if your dog’s leg measurement is 8 inches and his chest measurement is 10 inches, then he’d weigh 44.8 pounds.

Now that you’ve calculated your dog’s body mass, you can start figuring out how much Aspirin you should be giving them per day.

How Much Aspirin to Give a 70 lb Dog Based on Their BMI? 

Even though your dog may weigh 70 pounds, it’s important that you give a dosage suitable for its BMI, and don’t simply rely on weight alone.

If your dog has a BMI of less than 15, then they are considered underweight and should be given 1/2 tablet per day.

If your dog’s BMI is between 15 and 25, then he or she will be fine on the same amount of tablets as an adult human.

A dog with a BMI over 25 is considered obese and should only take 1/4 tablet daily.

Aspirin Dosage for Dogs – Different Types of Aspirin

It’s important to note that there are different types of Aspirin. Some contain acetaminophen, which is used to treat fever and pain. Others contain salicylates, which are used to treat arthritis and other inflammation-related conditions.

It’s recommended that you check the label on the bottle before giving your dog aspirin. If you don’t see “acetaminophen” listed on the label, then you should assume that the bottle contains salicylate-based aspirin.

When you buy aspirin for your dog, make sure you get the right type.

How Frequently Can You Give Your Dog an Aspirin Over the Course of a Day?

While it’s best to avoid giving your dog aspirin every single time they feel sick, it’s not always possible.

Giving your dog an aspirin once a week may help reduce their risk of developing heart disease. However, this isn’t something you want to rely on alone. It’s also important to keep your dog away from fatty foods such as bacon, butter, cheese, and eggs.

The American Heart Association recommends that dogs receive one aspirin per week. They say that giving your dog aspirin regularly could potentially lower their risk of developing heart problems. However, we would also recommend seeking out advice from a veterinarian before you do this. 

However, you shouldn’t give your dog aspirin every time they’re feeling unwell. Doing so could cause serious health issues.

If it appears that your dog is unwell, and you’ve been advised by a vet to give them aspirin, you should follow the instructions provided to the letter. However, as detailed above, the amount of aspirin you can give your dog depends on your dog’s BMI as follows:

  • BMI of less than 15 –  half a tablet per day
  • BMI between 15 and 25 – the same amount of tablets as an adult human per day
  • BMI over 25 – 1/4 tablet daily

Do Dogs Have Any Side Effects from Taking Aspirin?

There are some common side effects associated with aspirin. These include stomach upset, diarrhea, vomiting, and bleeding in the mouth.

These side effects are usually mild and last for just a few hours after you give your dog aspirin.

If your dog experiences any of these symptoms, then it’s likely that they’re experiencing a reaction to aspirin. You should stop giving your dog aspirin immediately and seek help from a veterinarian.

What Happens if My Dog Swallows an Aspirin Pill?

If your dog accidentally swallows an aspirin pill, they might experience abdominal pain or discomfort. This will go away within 24 hours.

In rare cases, your dog may develop ulcers in the lining of their stomach or intestines. In these instances, you should contact your veterinarian immediately.

What Happens If You Overdose Your Dog on Aspirin?

While most dogs won’t die from taking too many aspirins, some may experience side effects like vomiting, diarrhea, or even seizures.

In rare cases, dogs who ingest large amounts of aspirin can develop liver failure. If your dog is displaying any symptoms of liver failure, such as lethargy, vomiting, or loss of appetite, then you should take them to the vet immediately.


You should never give your dog aspirin without first consulting a vet. Aspirin can be dangerous for dogs.

It’s possible that your dog could experience a number of side effects including nausea, diarrhea, vomiting, or even seizures. If you’re unsure about what dosage to give your dog, then you should consult a vet.

However, if this is not possible, the correct dosage to give depends on the dog’s BMI, as we described for you earlier.
