AZO For a Pet Dog’s UTI? Read This First!

Last Updated on

Are you wondering if Azo can help your dog with a urinary tract infection?

Straight to the point:

The Standard, Value Size and Maximum Strength versions are too dangerous. Anything with phenazopyridine as the active ingredient is off limits to pets.

Can I Give My Dog AZO?So despite being readily available over-the-counter, Azo can be harmful for your dog.

Hemolysis, or destruction of red blood cells, is of particular concern. But muscle and liver damage are also possible.

Do Not Give Your Dog AZO®

While people have administered this OTC analgesic to their animals without incident, we do not recommend it.

Phenazopyridine Too Risky

Clearly Azo is not intended for canine use — nor is it safe for treating bladder problems!

Case in point:

A Chihuahua experienced muscle hyperesthesia after being given phenazopyridine according to the National Center for Biotechnology Information (NCBI).

Take your chances providing this urinary pain reliever and your dog could suffer side effects. Don’t do it!

AZO Isn’t a Fix Anyway

AZO tablets, and similar drugs, are not remedies for bladder infections.

Your dog may get short-term relief because that is what analgesics do.

Any benefit would be temporary and, more importantly, there are numerous potential downsides including:

  • Stomach pain
  • Nausea
  • Vomiting

Warning: Your dog could require blood work to rule out liver damage or anemia.

More Reasons To Avoid 

It gets worse!

Phenazopyridine formulations, AZO included, are all wrong for dogs due to a possibility of Rhabdomyolysis which is yet another muscle-related complication.

Further, Azo may be carcinogenic though this has only been proven in lab rats — not dogs.

Nevertheless, please heed the concerns including rare situations where red blood cells could be affected by Phenazopyridine (AKA Pyridium).

A Safe AZO Alternative

Why not use a natural, safe remedy rather than giving your dog an over-the-counter or prescription medication?

But wait!

Cranberry also cannot fix nagging symptoms associated with urinary tract infections and other bladder urgency issues — meaning Azo’s other products are also ill-advised.

On the other hand, chamomile tea may help your dog a bit.

Above all else remember that your vet deals with urinary tract infections all the time. Give them a call!

A Prescription Antibiotic

You may need to obtain some sort of prescription medication for your pet’s infection.

Often times an antibiotic is the solution for stubborn bladder problems.

Azo, even a relatively safe version, is not the right approach for helping your dog.

Act Soon For a Dog’s UTI

It can be difficult to spot a UTI in the early stages. Again, you really should get a professional’s expertise if you’re uncertain.

The thing is most urinary infections are already in the advanced stages by the time a dog typically exhibits obvious signs.

A vet visit will ensure that your buddy gets the right treatment. Save the Azo for human use.

The Bottom Line

It is not safe to give your dog Azo for a urinary tract infection or any other reason.

We favor natural remedies but it could be that a vet’s antibiotic prescription is necessary.

One thing is certain:

Providing your dog with phenazopyridine, the active ingredient in Azo, is not worth the risk.

  1. My 14 year old German Shepherd is peeing blood. She is also agitated and uncomfortable, needing to walk and drink water. It is storming badly outside and we are not in our own house right now. What would be best for her right now?

  2. My dog is exhibiting the signs and symptoms of a UTI. It’s a national holiday and I cannot locate an open vet. She is miserable. Any suggestions?

  3. Is there an over-the-counter product I can use for my dog’s urinary infection?

    1. My vet suggested cranberry powder for my Maltese/Bichon. I have used it, about 1/2 teaspoon in her evening meal, every second day and found it quite successful. It’s worth a try.

  4. I believe my Shih Tzu has a UTI and I brought her to the vet for treatment. But the prescribed antibiotics did not help. She is under 10 pounds and I want to try AZO. What would the correct dose be? Please advise.

    1. If the antibiotic your pet’s UTI didn’t respond to was prescribed, you need to let your vet know. They can culture the urine and prescribe a more specific antibiotic. AZO only relieves the symptoms, it doesn’t cure anything.

      1. Azo is very dangerous for your dog. Check with your vet!
