Can I Give My Dog Mucinex?

Can I Give My Dog Mucinex?Mucinex is a popular oral medication but it’s a question mark for dogs. It reduces congestion and those with cold symptoms take this product to eliminate excessive phlegm in the throat and/or suppress a cough. Tempting for a sick pup!

So can Mucinex be safely used for treating a dog as well? In fact, this over-the-counter medication has been successfully given to canines to treat the same issues. There are, however, a few important things you should know before you administer it.

First off, and for your dog’s sake, do not experiment with potentially harmful human-formulated medications. Before using Mucinex, you really should consult with a vet because they can provide a definitive diagnosis.

Can I Give My Dog Mucinex? Answer: Yes, but it’s not a cure

It can clear up your dog’s occasional congestion or throat phlegm but it won’t help with a chronic respiratory illness.

Mucinex, drug name Guaifenesin, generally works well for dogs but not for undiagnosed conditions requiring professional treatment. Something like Kennel Cough may appear to respond well to this well-known expectorant but better treatment options exist. In any case, Guaifenesin products are considered safe for dogs when used appropriately. Regular Mucinex Expectorant and the DM version both contain lower doses of Guaifenesin which is good for safely reasons.

Another option to consider is Hound Honey which receives great reviews.

Options for Administering

Mucinex can be given to dogs orally in either liquid (syrup) or tablet form just like Robitussin. Both forms and brands are effective. Choose one that’s easier to administer to your dog. Liquid forms are popular and you can either use a dropper directly, or mix the medicine into their food or drinking water.

Alternatively, you can break up the tablets and put them into dog food. Other owners are good at placing tablets down the throat. With this method you can give Mucinex to your dog in just a few seconds.

Proper Mucinex Dosing

We are hesitant to provide a recommended dose because there are many factors and each dog has their own situation. However, the general rule of thumb is 20mg to 40mg per pound of body weight taken every 12 hours or so. Careful with Mucinex products as several kinds contain 1,200mg per regular dose!

On the flip side, be sure that your dog consumes all the food or water containing the Mucinex so the proper dosage enters their system. Otherwise, the medicine may not work as effectively. So it may be best to place the full dose in a small amount of food or water so it can be consumed in one gulp.

A Great Natural Remedy

One teaspoon of pure honey, given three times daily, may provide relief just as effectively as Mucinex. It can loosen up congestion and speed up a recovery. It’s safer and honey contains natural vitamins and minerals that may also strengthen your dog’s immune system.

Sometimes supplements are beneficial when a dog is sick or under stress. Vitamin C is crucial if they aren’t naturally producing enough of it. Speak with your vet about it!

Problems Linked to Coughing

Sure, Mucinex can ease certain chest and lung symptoms but it may be necessary to have a vet look at your dog. This is especially true if they’re frequently experiencing such symptoms. Recurring issues, including a bad cough and excess phlegm, can be a sign of other pulmonary problems or even a heart condition. If this is a real concern, the veterinarian will perform some tests. Consider it peace of mind. Besides, Mucinex isn’t a cure-all.

Coughing with heavy breathing can be a sign of pneumonia which requires immediate veterinary care.

Conclusion on Mucinex

You can provide a proper dose of Mucinex to your dog if they’re dealing with a bout of excessive mucus-like Phlegm. On the other hand, get your best buddy to a vet if the problem persists since they could have a chronic respiratory issue requiring prescription antibiotics and closer medical attention. If you do use Mucinex, go with the lower dose product lines. Otherwise, consider a herbal alternative made specifically for dogs.

My vet just told me to use 1 Mucinex (600mg) a day for my almost 50 pound Basset Hound. I believe he looked this information up on VIN. I noticed that Mucinex can be given twice a day. According the dosage recommended in this article this would be on the low end for my dog’s weight.

So I went to get Mucinex for my dog and as I am headed to check out, I see that it contains Acetaminophen which is Tylenol! Just three Tylenol can kill a full size dog via liver failure. I checked to see the amount and it said 325mg. Do not give this to your dogs!

Supply plenty of fresh water because Mucinex, or it’s generic version, has a drying effect. The extra fluids will help to move the mucus out.

My Aussie has nasal cancer. She is on a low dose of Prednisone and I don’t think we are far from having to put her down. Nasal mucus is the biggest problem. Once she sneezes, and gets rid of some of the mucus, she breathes pretty well. Can I give her Mucinex with the Prednisone to make her more comfortable and get rid of some of the mucus? Thanks for the help.


Christine June, 2015

Hi Sara. You can give your dog some NAC (n-acetylcysteine) to help reduce the mucous build up. It works well for my dog’s cancer. Eucalyptus radiata taken internally, make sure to buy the one that is marketed for internal use, helps expel the mucus and also seems to be killing off the cancer in my dog’s lungs and heart. Andrographis paniculata is another amazing herb for cancer treatment which reduced the tumor in my dog’s tummy from a grapefruit to golf ball size in just a couple weeks. Artemisinin is another on my must have list.

I was planning on putting my dog down before starting these supplements but now he is almost back to his regular self after only a few weeks of starting these incredible herbs. I also give my dog CoQ10, chlorella, a multi-vitamin, vitamin-C, astragalus, echinacea and RSO (Rick Simpson oil). My friends are amazed at how great my Yogi is doing now compared to a month ago. I love him so much, I am just not willing to give up quite yet.

Please do look these herbs up online. A good place to check is called “Pubmed”. It’s loaded with peer reviewed medical research. You just search within the Pubmed site and you will find piles of useful info. But in my humble opinion, Prednisone is poison. I refused to give it to my dog as it destroys the immune system while reducing the inflammation. My choice for inflammation reduction treatment would include turmeric.

My 13 year old Miniature Pinscher weighs 15 pounds and has a heart congestion. She takes two meds but her cough has lasted 2 days and it’s so bad. My vet can’t see her for 3 weeks. I read about mucus and cough relief. Can I give something like that to my dog and how much?


Jena April, 2015

If your dog’s cough is that bad, and your vet will not see her for three weeks, I would suggest finding a new veterinarian. Is there another clinic that you can take her to in the meantime? Your current one can send over their records to the new vet so that they can make a proper diagnosis and prescribe something for the cough.

I have a 60 pound female Boxer. I just heard her coughing last night and again today. After reading this article, I feel confident in giving her Mucinex. I’m just worried about the amount. Can you recommend a dosage until Monday when my vet comes back and can take a look at her. Or what about (Delsym) Dextromethorphan?


Susan November, 2014

After spending thousands of dollars treating my dogs for pneumonia and chronic bronchitis, I bought Mucinex. Within 2 days she was bringing up all the phlegm that had been in her lungs. I give her 1/4 of a Mucinex twice a day for a 40 pound dog.


Jan November, 2014

Is that in liquid or pill form?


Dolly January, 2015

What dose of Mucinex would you recommend that I give my Chihuahua?


Tanyar February, 2015

The vet just told me, for my 5 pound Chihuahua, 100-200mg but with no Ephedrine.


Susan November, 2015

I read your comment about your dog and use of Mucinex. How is she doing? I have a dog with the same thing. I’ve spent so much money without good results. Thank you.

Our Border Collie has a respiratory sickness. 2 nights ago she coughed, hacked and sneezed two hours non-stop. She was in obvious pain. It was the weekend so a vet was out of the question. We had tried Robitussin liquid but it was very difficult to administer. She did not respond.

Yesterday I bought Mucinex tablets. It has 2 times the guaifenesin (expectorant) as Robitussin. We put it in a hamburger ball and she gulped it down. Last night she slept like a baby. This morning she is alert without one cough. This may not last but if the past 24 hours are any indication, it is nothing less than a miracle.


Don November, 2014

This is a follow up. I made a mistake on my last post. The pill we gave our Border Collie was not Mucinex. It was a generic version. My pharmacist at Walmart told me to try Mucus Relief Cough which is on the lower shelf and is only $2.48 for a 30 count, tremendously cheaper than Mucinex. The pharmacist said Guaifenesin 400mg is what gets rid of the mucus. That is a tad lower than Mucinex but it worked like a charm. Our little girl is now on the mend after suffering for months. 5 vet visits, hundreds of dollars out the window when $2.48 did the trick.


DeNene March, 2015

How much does your Border Collie weigh and how often did you dose her? I have a 13 year old, 65 pound rough Collie with a productive cough from his throat with a lot of thick phlegm. Even though he’s not running a fever and his appetite is fine, I’ve started him on antibiotics empirically due to his age. It’s helping a lot, but I’d like to be able to thin the phlegm up so he could cough it up easier. I have the generic Mucus Relief 400mg. Thanks!


Crystal December, 2014

Do you have to give a lot of water with Mucinex?


Barbara July, 2013

Thanks for letting me know Mucinex is okay for dogs and for informing people that Advil is not good for dogs. As a former vet tech, I am asked that question all the time.


James July, 2013

Hi Barbara. Thanks for kind words. If you would like to become a regular contributor to this site please let me know. We could use your expertise.


Jack Reeves May, 2013

Thanks for the info, but could you add a general recommended dose per pound of the dog?


James June, 2013

I would hesitate to offer dosage recommendations. Please consult with your vet on that!
