When our furry companions fall ill and require antibiotics, it’s natural for us, as pet owners, to feel concerned not just about the illness itself but also about how we can best support their recovery.

Antibiotics, while essential for fighting off infections, can sometimes lead to uncomfortable side effects for our dogs, particularly when it comes to their digestive health.

What To Feed A Dog During Antibiotic Therapy

This guide is designed to provide you with comprehensive, vet-approved advice on what to feed your dog while they are on antibiotics.

Our goal is to help you ensure that your dog not only recovers effectively but also maintains optimum health and comfort throughout their treatment.

What to Feed Your Dog on Antibiotics

The key to supporting your dog while on antibiotics is to focus on a balanced, nutritious diet that is easy on their stomach.

High-quality, easily digestible foods are paramount. Ideally, you should feed your dog a diet rich in lean proteins, simple carbohydrates, and probiotics.

Boiled chicken, white rice, and pumpkin can provide the necessary nutrients without overburdening your dog’s digestive system.

Additionally, incorporating probiotic supplements, as recommended by your veterinarian, can help maintain healthy gut flora disrupted by antibiotic treatment.

Balanced Diet for Immune Support

High-Quality Proteins:

Lean meats like chicken or turkey are recommended to support tissue repair and bolster immune function. These easily digestible sources of protein are less taxing on the digestive system, which can be sensitive during antibiotic treatment.

Simple Carbohydrates:

Foods such as white rice and sweet potatoes provide easily accessible energy, helping to minimize digestive stress. Their simplicity aids in maintaining energy levels without overwhelming the gastrointestinal tract.

Fiber-Rich Foods:


Incorporating small amounts of pumpkin or plain, boiled vegetables can help regulate digestion. Fiber aids in maintaining bowel health and can assist in preventing diarrhea, which can sometimes be a side effect of antibiotic use.

Probiotics and Gut Health

The use of probiotics, particularly yeast-based ones like Saccharomyces boulardii, is crucial for restoring gut balance during and after antibiotic treatment.

Unlike bacteria-based probiotics, S. boulardii is not affected by antibiotics and has been shown to reduce digestive issues and support the growth of beneficial gut bacteria.

Adding prebiotics such as psyllium husk powder or inulin can further support gut health by promoting the growth of beneficial bacteria, helping the gut microbiome to rebuild after disturbances caused by antibiotic treatment.



Ensuring constant access to fresh water is essential for preventing dehydration, a risk that increases during illness and when on antibiotic medication. Proper hydration supports overall health and aids in the recovery process.

Foods To Avoid While Your Dog Is on Antibiotics

It’s important to avoid foods that may interfere with antibiotics, like dairy products, which can bind to certain medications and reduce their effectiveness.

High-fat foods, spicy foods, and any known allergens should also be avoided to prevent exacerbating digestive issues.


Studies have underscored the beneficial effects of S. boulardii in combination with healthy probiotic bacteria and prebiotics in protecting against antibiotic-induced gastrointestinal signs in dogs.

Such interventions not only mitigate immediate side effects like vomiting and diarrhea but also contribute to longer-term gut health and well-being​​​​​​​​.

For a more detailed exploration of how to support your dog’s gut health during and after antibiotic treatment, consider consulting with a veterinarian for personalized advice.


How long should my dog stay on a special diet after finishing antibiotics?

After completing antibiotic treatment, it’s wise to continue the special diet for at least a few days to a week, gradually reintroducing their regular food while monitoring for any signs of digestive upset.

Always consult with your vet for personalized advice.

Can I give my dog over-the-counter probiotics meant for humans?

It’s generally recommended to use probiotics specifically formulated for dogs rather than human products, as dogs have different gut flora. Your veterinarian can recommend the best option for your pet.

What signs indicate that my dog is having a bad reaction to their antibiotic?

Signs of a bad reaction can include vomiting, excessive diarrhea, skin rashes, or lethargy. If you notice any of these symptoms, contact your veterinarian immediately.


Caring for a dog on antibiotics demands a delicate balance of the right nutrition and constant observation. By focusing on easily digestible, nutritious foods and incorporating supplements like probiotics, you can significantly aid your dog’s recovery process and overall well-being.

Remember, every dog is unique, and what works best can vary. Always consult with your veterinarian to tailor dietary choices to your dog’s specific health needs.

As pet owners, our awareness and actions play a crucial role in our pets’ health, demonstrating our love and commitment to their well-being.
