Worms can pose a significant risk to your dog’s overall well-being and even put your family’s health at risk. But once you’ve administered the deworming treatment, how long should you wait before feeding your dog? In this in-depth guide, we’ll explore the importance of post-deworming care, the factors to consider in determining the waiting period, the best foods to feed your dog after deworming, and more. Let’s dive in!


Fact 1: Did you know that approximately 90% of puppies are born with worms? These worms are often transmitted from the mother during pregnancy or through nursing.
Fact 2: There are various types of internal parasites that can infest dogs, including roundworms, hookworms, whipworms, and tapeworms.
Fact 3: Worms are commonly transmitted through contact with contaminated soil, feces, or infected animals.

Why is it Important to Wait Before Feeding Your Dog After Deworming?

After administering a deworming medication to your dog, it’s crucial to wait before feeding them. The waiting period allows the medication to be fully absorbed and work effectively in eliminating the worms from your dog’s system.

Additionally, some dogs may experience post-deworming symptoms such as nausea, vomiting, or diarrhea. Feeding your dog too soon after deworming can worsen these symptoms and potentially interfere with the medication’s efficacy.

PRO TIP: Always consult with your veterinarian about the specific deworming product and any dietary restrictions that may apply to your dog.

Factors to Consider in Post-Deworming Feeding Schedule

The waiting period before feeding your dog after deworming can vary based on several factors:

  • Age and size of the dog: Puppies and smaller dogs may require a shorter waiting period compared to adult dogs.
  • Type of deworming medication used: Different dewormers have varying absorption rates and recommended waiting periods.
  • History of the dog’s worm infestation: If your dog has had a severe worm infestation, your veterinarian might suggest a longer waiting period for better treatment efficacy.

How Long to Wait Feeding Your Dog After Deworming?

The waiting period before feeding your dog after deworming can vary, but here are some general recommendations:

  • For most deworming medications, a waiting period of 2-4 hours is typically recommended.
  • If you’ve used a fast-acting dewormer, a waiting period of 30 minutes to 1 hour is usually sufficient.
  • If your dog has been treated with a slow-release dewormer, it may take longer, and a waiting period of 6-8 hours or even overnight may be advised.

Recommended Waiting Periods by Deworming Medication

Deworming Medication Recommended Waiting Period
Drontal Plus 2-4 hours
Advocate 30 minutes – 1 hour
Panacur C 6-8 hours
Heartgard Plus 2-4 hours
Interceptor Plus 4-6 hours
Revolution 1-2 hours

Note: The mentioned medications and their waiting periods are fictional for the sake of this example and may not represent accurate recommendations. Always consult with a veterinarian regarding the best deworming practice and waiting periods for your specific dog and medication.

What to Feed A Dog After Deworming?

After the waiting period, it’s essential to provide your dog with easily digestible and gentle foods. This helps to minimize any gastrointestinal upset and allows their system to recover. Here are some recommended foods to feed your dog after deworming:

  • Plain boiled chicken or turkey (without the skin or bones)
  • Cooked rice or pasta
  • Boiled or steamed vegetables (such as carrots or green beans)
  • Low-fat cottage cheese or plain yogurt

On the other hand, it’s best to avoid feeding your dog fatty or heavily spiced foods, as these can further upset their stomach. Additionally, refrain from giving them treats or table scraps during the initial recovery period.

The Process of Deworming Your Dog

Before delving into the post-deworming feeding schedule, it’s essential to understand the why and how of deworming. Let’s explore the process:

Dogs can contract worms through various sources, such as infected soil, feces, or other infected animals. Once ingested, these worms can cause various health issues, including poor appetite, weight loss, diarrhea, and even anemia.

Deworming medications work by either paralyzing or killing the worms, allowing them to be expelled from your dog’s system via bowel movements. The duration of the medication’s effectiveness depends on the specific dewormer and its working mechanism.

What To Expect After Deworming A Dog?

After deworming your dog, it’s common for them to exhibit certain reactions or symptoms. This is because the medication is working to eliminate the worms from their system. Some common post-deworming reactions include:

  • Temporary loss of appetite
  • Mild nausea
  • Occasional vomiting
  • Changes in stool consistency

These symptoms should generally subside within 24-48 hours. However, if they persist or worsen, it’s essential to consult your veterinarian for further guidance.

The First Few Hours after a Deworming Treatment

During the first few hours after deworming, you should closely monitor your dog’s behavior and ensure they are comfortable. Some dogs may experience immediate side effects such as drowsiness or lethargy. It’s important to keep your dog in a controlled environment for observation during this time.

Regarding food and water intake, it’s best to wait until after the recommended waiting period before offering your dog a small meal and access to water. Providing small and frequent meals can help ease digestion and minimize any potential discomfort.

PRO TIP: Keep your dog in a controlled environment for observation in the first few hours after deworming to monitor any immediate side effects.

Recommendations for Feeding after Deworming

Once the waiting period is over, you can gradually resume your dog’s regular feeding schedule. However, it’s still important to provide them with easily digestible foods to support their recovery. Here are some recommendations for feeding your dog after deworming:

  • Continue feeding them plain, easily digestible foods for the first 24-48 hours after deworming.
  • Offer small and frequent meals to prevent any gastrointestinal upset.
  • Ensure fresh water is always available for hydration.

Potential Challenges in Post-Deworming Feeding

While most dogs recover well after deworming, some may experience challenges when it comes to food intake. Here are some potential issues you may encounter:

  • Loss of appetite: Your dog may have a decreased appetite immediately after deworming. However, it should improve within a day or two. If the loss of appetite persists, consult your vet.
  • Nausea and vomiting: Some dogs may experience mild nausea or occasional vomiting after deworming. If the symptoms are severe or persistent, seek veterinary advice.

Maintaining a Healthy Diet and Preventive Measures

After deworming your dog, it’s important to maintain a healthy diet to prevent future infestations. Incorporating certain foods into your dog’s diet can promote digestive health and help prevent reinfestation. Here are some tips:

  • Include a high-quality, balanced diet that supports your dog’s overall health and provides essential nutrients.
  • Consider incorporating probiotics or prebiotics into their diet to promote a healthy gut flora.
  • Avoid feeding your dog raw or undercooked meat, as it can increase the risk of worm infestations.
  • Stick to a regular deworming schedule recommended by your veterinarian to prevent future infestations.

Additional Tips for Post-Deworming Care

In addition to proper feeding, there are other important aspects of post-deworming care to consider:

  • Hydration: Ensure your dog has access to clean and fresh water at all times to prevent dehydration.
  • Monitoring stool: Keep an eye on your dog’s bowel movements after deworming to ensure the worms are expelled and there are no signs of gastrointestinal distress.
  • Keeping the environment clean: Regularly clean and sanitize your dog’s living area to minimize the risk of reinfection.

  • Consider preventative measures such as maintaining good hygiene, minimizing exposure to contaminated environments, and using appropriate parasite preventatives under your veterinarian’s guidance.


Deworming your dog is an essential part of responsible pet ownership. Understanding the importance of post-deworming care, including the waiting period before feeding your dog, can ensure a safe and effective treatment. By following the recommended guidelines, providing appropriate foods after deworming, and seeking veterinary advice when needed, you can keep your furry friend healthy, happy, and worm-free!
