Can you give a dog baby aspirin?

Aspirin has the same problems in dogs that it has in people. It

can cause gastrointestinal upsets and ulcers if the GI signs are

ignored. It can cause renal failure if overdosed. It causes an

increase in clotting time. This usually isn't a serious side effect

but it does occur. Despite these shortcomings it has a lot of

beneficial effects and it is inexpensive. The currently recommended

dosage of aspirin varies a little from publication to publication

but it is between 5 and 15mg/lb every 12 hours. Since there is a

range I usually pick the middle of it and go for about 10mg/lb

every 12 hours. This works well and seems to be pretty safe. That

works out to an aspirin tablet per 32 pounds of body weight twice a

day. I have to admit that I rarely advise giving more than 2

aspirin twice a day despite the fact that some big dogs could

obviously take more based on the per pound calculation.

If your dog has chronic pain or inflammation, common aspirin can

often be used to give your pet some relief. Since aspirin can cause

some stomach problems, care should be used. It is wise to check

with your vet before administering aspirin or any other


Dogs are most commonly given aspirin for treatment of arthritis

and associated joint pain. There may be other situations where your

dog is in pain, where aspirin may give relief.

Aspirin has good anti-inflammatory effects that reduces

swelling. It can also reduce pain and fever. These effects will

help make your dog more comfortable.

Note that a dog is not a human. Just because your dog "does not

feel good" is not a reason to give it an aspirin. Usually, aspirin

is given to relieve extreme conditions of discomfort. Also note

that most vets prescribe Rimadyl as a better pain-killer and

anti-inflammatory than aspirin.

Use caution:

You should use caution in administering any medication to a pet,

because too much may be toxic, the medicine may not be tolerated,

or it can cause an upset stomach or ulcers in the animal.

It can be toxic if given in high doses of about 30 mg per pound

of the dog. This means that even baby aspirin could be poisonous

for dogs weighing two pounds or less. An adult aspirin which is 320

mg. would be toxic for a 10-pound dog. To be sure that you are

using the aspirin for the right reason and at the right dose, you

should consult your veterinarian first.

Aspirin is poorly tolerated by young dogs, since they lack the

enzymes necessary to process the aspirin. The same is true for most


Aspirin can cause gastrointestinal upsets and ulcers in dogs,

just as in humans. You should pay attention to your dog's eating

habits when administering aspirin to watch for signs of an upset

stomach. If there are any signs of ulcers, such as blood-tinged

vomiting, it is important to stop the aspirin.

Giving the aspirin with food and using buffered aspirin is the

best to prevent stomach problems.

I prefer to grind up the aspirin and put it in some food to make

sure it does not irritate the stomach lining.

You should not give your dog such products as Tylenol as a

substitute for real aspirin. Some people say their vet prescribed

Tylenol, but most sources say it should not be given to


Recommended Dosage:

Most veterinarians recommend between 5 mg and 10 mg per pound of

the dog's weight every 12 hours. Going on the safe side, a

recommended dosage of aspirin of about 5 mg/lb seems to work well

for most dogs. If you are going to give more, it is a good idea to

check with your vet. Also, note that a small dog should take less

per pound. Enteric coated aspirin is not recommended in dogs

because about half the time the coating isn't digested and the

aspirin is excreted whole in the stool.

It is better to start off small and work your way up to the

maximum. If the dog has relief with a smaller dosage, that is


A standard aspirin is 320 mg. A baby aspirin is typically 80 mg.

That means that 5 mg/lb works out to be one baby aspirin per 16

pounds of body weight twice a day.

The following chart can be used as a guide. Note that this is

notmedical advice.

The proper dosage of aspirin can give your dog relief from pain

and inflammation. You should be aware of possible problems and know

the proper dosage. It is good to check with a vet before giving any

medication, and remember that dogs are not humans and don't need an

aspirin for minor pains.

Yes, though with caution. The typical dog dosage for aspirin is

5-15 milligrams per pound every 12 hours. However, it has the same

possible problems in dogs as in people, just as stomach upset,

ulcers, and kidney failure. It is useless to give coated aspirin.

Dogs typically cannot digest the coating, thus the aspirins are

excreted whole.

Some vets say aspirin is bad for a dogs liver. I would call your

vet and get their recommendation. This way you will know for sure

and if it is ok then you can get the correct dosing


I wouldn't advise giving the dog asprin, There are painkillers

designed for dogs/cats. There digestive system is different to ours

and so by giving them asprin you may cause them harm. If you are

desperate, give a half a tablet and watch the dogs behaviour. If

his behaviour becomes abnormal, you may need his stomach pumped...

Or for him to be made sick which would be messy and


Yes, dogs can have aspirin, but make sure it is buffered, and check

with your vet for dosage. If it is for a chronic problem like

"arthritis">arthritis, there are better alternates out there

that are not as hard on their stomach.
