Customer Question

I have a 2 year old golden doodle and for the past 6 months or so he coughs up mucus occasionally and of course it always on the carpet and not on the floor. Last night he woke me up gagging and spit up. Other than that he seems very healthy and is very active.

Hi Sir or Madam,
My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
In order to supply you with an informed answer, it is necessary for me to collect some additional information from you. When I receive your response or reply, it will likely take me between 30-45 minutes to type up my reply if I am still online when I receive notice that you replied. I hope you can be patient.
When was his last vet visit?
Has your vet checked his heart and lungs?
How often is he fed?
When is his last meal?
When does this usually occur?
Is it mostly at night or early morning?
Has he ever been on antibiotics?
Customer: replied 2 years ago.
Check up was March 05. Yes, my vet gave him a thorough check. He eats small amounts twice a day and his last meal was 8 AM. It can occur anytime, mostly during the day but it has happened early morning once and last night was the first for the middle of the night. No, he has never been on antibiotics.

It is not that unusua1 for a dog that is coughing to produce some mucous. Often with coughing they will also trigger the vomiting of a small amount of mucousy fluid from the stomach. There are many different causes of coughs as well. Let me go over the various causes first.
Dogs can develop upper respiratory illnesses such as kennel cough and canine influenza as well as bronchitis and inhaled allergies. Kennel cough should have resolved by now as would have canine influenza. You can read about bronchitis here:
Allergies are a good possibility. If he has sneezing and nasal congestion that could be due to an allergic reaction to an inhaled substance. If this is the case, Benadryl can be given to your dog, the dose is up to 2mg per pound every 8 hours. This would help with the coughing and stop the spasms that might be causing the mucous to come up.
You can read about these here.
Since kennel cough usually resolves in 3 weeks that is an unlikely cause as is influenza. Here is a website with more information on kennel cough.
If your dog has a colored discharge from the nose or eyes, stops eating or lethargy. These are signs of a possible bacterial infection as well and my require antibiotics. Normally a productive cough (coughs stuff up) is cause for a vet visit, so you need to try and determine if he is gagging and bringing up stomach contents or productive cough.
To help your dog breathe easier you can run a NON-medicated humidifier in the room your dog is in, or sit in a steamed up bathroom with your dog to help keep the mucous moving. Robitussin DM at a 1/4 teaspoon per 5 pounds can be used to control the cough. It should only contain dextromethorphan and Guaifenisen. and should NOT contain pseudoephedrine. Dosages can be obtained at this website.
There are other reasons for coughs such as heart problems which should be investigated if your dog is not on heartworm preventative The following site goes over canine coughs.
If your dog has ever had a neck injury or collar injury, tracheal collapse might be a cause as well.
Now one thing that I feel might be going on is acid reflux or excess bile. It can cause a dog to have irritation to the throat and coughing. It is frequently the cause for a dog to gag and bring up mucousy bile. Increasing his meals to smaller portions 3 times a day might help. You might also give some pepcid or Zantac. Read about Pepcid dosages and usage information here:
Zantac can be given to a dog at .25 to 1mg per pound every 8-12 hours. Read about usage here:
If your dog has food in his belly on a regular basis throughout the day, it cut down on excess bile. I'd also add a spoonful of plain yogurt to your dog’s food 2-3 times a week to add good bacteria to your dog’s stomach to aid in digestion as well. The bland diet of boiled chicken and rice can be used for a few days. If your dog does fine, you can slowly reintroduce your dog’s regular food into the chicken and rice mixture until it is all regular food.
Of course, you can discuss all this with your vet as well. I hope this information is helpful to you. If you need more information or clarification, please reply and I'll get back to you as soon as possible. If you are satisfied, please take the opportunity to rate.
