Why Might Dogs Not Like NexGard? Understanding Palatability and Adverse Reactions
This article explores why some dogs might show aversion to NexGard, focusing on both palatability challenges and the possibility of adverse reactions that could lead to a negative association with the medication.
Introduction: The Popularity and Potential Pitfalls of NexGard
NexGard is a widely prescribed chewable medication designed to protect dogs from fleas and ticks. Its effectiveness and ease of administration have made it a popular choice among veterinarians and pet owners alike. However, despite its proven benefits, some dogs display an apparent dislike for NexGard. Understanding the potential reasons behind this aversion is crucial for ensuring consistent parasite control and maintaining your dog’s well-being. We will explore several factors contributing to this phenomenon, ranging from taste and texture preferences to rare, yet possible, side effects.
Palatability: Taste, Texture, and Individual Preferences
One of the primary reasons why dogs do not like NexGard could be simply related to its palatability. While manufacturers formulate the chewable tablets to be appealing, taste is subjective, even for dogs.
- Taste Preferences: Just like humans, dogs have individual taste preferences. What one dog finds delicious, another might find unappealing. The flavoring agents used in NexGard might not be universally enjoyed.
- Texture Sensitivity: The texture of the chewable tablet could also be a factor. Some dogs prefer crunchy treats, while others prefer softer options. A dog might dislike the chewy or slightly rubbery texture of NexGard.
- Prior Negative Experiences: If a dog has ever associated a medication with a negative experience (e.g., feeling unwell afterward), they might develop an aversion to anything resembling it, including NexGard.
The Role of Food Sensitivities and Allergies
While NexGard itself is designed to be safe, some dogs might have underlying food sensitivities or allergies that could be triggered by inactive ingredients within the medication. Though rare, such reactions could manifest as gastrointestinal upset, leading to a negative association with the chewable.
- Inactive Ingredients: NexGard contains inactive ingredients like corn starch, soy, and artificial flavors, which can be potential allergens for some dogs.
- Gastrointestinal Discomfort: Allergic reactions or sensitivities can cause nausea, vomiting, or diarrhea. If these symptoms occur shortly after administering NexGard, the dog might associate the medication with the discomfort.
Understanding Potential Adverse Reactions
Although NexGard is generally well-tolerated, some dogs can experience adverse reactions. While most side effects are mild and transient, they can contribute to a dog’s dislike of the medication.
- Common Side Effects: The most commonly reported side effects of NexGard include vomiting, diarrhea, lethargy, and decreased appetite.
- Neurological Concerns: In rare cases, neurological signs such as seizures or ataxia (loss of coordination) have been reported, particularly in dogs with a history of seizures. It’s important to note that the correlation between NexGard and seizures is still under investigation, but such a reaction would certainly cause a dog to avoid the medication.
- Breed Predispositions: Some breeds, such as Collies and other herding breeds, may be more sensitive to certain medications due to a genetic mutation known as the MDR1 mutation. This mutation can affect how a dog processes certain drugs, potentially increasing the risk of adverse reactions.
Strategies for Successful NexGard Administration
If your dog dislikes NexGard, there are several strategies you can try to make the process easier.
- Disguise the Tablet: Wrap the NexGard tablet in a small amount of highly palatable food, such as cheese, peanut butter (xylitol-free), or cooked chicken.
- Pill Pockets: Use commercially available pill pockets, which are specially designed treats with a hollow center for concealing medication.
- Administer on an Empty Stomach: Sometimes, administering NexGard on an empty stomach can improve absorption and reduce the likelihood of gastrointestinal upset. However, always consult your veterinarian first.
- Positive Reinforcement: Reward your dog with praise and a special treat immediately after they take the medication. This helps to create a positive association with the experience.
- Consult Your Veterinarian: If your dog consistently refuses NexGard or experiences adverse reactions, talk to your veterinarian. They can help you determine the underlying cause and recommend alternative flea and tick preventatives.
Alternative Flea and Tick Preventatives
If your dog truly refuses to take NexGard or experiences adverse reactions, there are several alternative flea and tick preventative options available.
| Preventative | Form | Administration |
|---|---|---|
| —————- | —————- | ————————————————- |
| Bravecto | Chewable Tablet | Administered orally every 12 weeks. |
| Simparica | Chewable Tablet | Administered orally every 30 days. |
| Revolution | Topical Solution | Applied topically to the skin monthly. |
| Frontline | Topical Solution | Applied topically to the skin monthly. |
| Seresto Collar | Collar | Worn continuously for up to 8 months. |
Choosing the best preventative for your dog depends on various factors, including their age, breed, health history, and lifestyle. Your veterinarian can help you weigh the pros and cons of each option and recommend the most appropriate choice for your individual pet.
Frequently Asked Questions About NexGard Aversion
Here are some frequently asked questions about why dogs do not like NexGard, offering further insights into its use and potential issues.
Is NexGard safe for all dogs?
NexGard is generally safe for most dogs when used according to the manufacturer’s instructions and under the guidance of a veterinarian. However, it’s not recommended for puppies under 8 weeks of age or dogs weighing less than 4 pounds. Additionally, caution should be exercised when using NexGard in dogs with a history of seizures or other neurological conditions. Always consult with your veterinarian to determine if NexGard is appropriate for your individual pet.
What are the signs of an allergic reaction to NexGard?
Signs of an allergic reaction to NexGard can vary but may include hives, facial swelling, difficulty breathing, vomiting, diarrhea, and lethargy. If you suspect your dog is having an allergic reaction to NexGard, contact your veterinarian immediately.
Can I crush or break the NexGard tablet to make it easier for my dog to take?
While you can technically crush or break the NexGard tablet, it is generally not recommended. Doing so could affect the palatability and potentially alter the effectiveness of the medication. It is always best to administer the tablet whole, if possible. If you are struggling to give your dog the tablet, try concealing it in a pill pocket or a small amount of highly palatable food.
Does NexGard have any interactions with other medications?
NexGard is generally considered safe to use with most other medications. However, it’s always best to inform your veterinarian of all medications and supplements your dog is taking to ensure there are no potential interactions.
How long does NexGard take to start working?
NexGard starts working within 30 minutes to kill fleas and within 48 hours to kill ticks. It provides protection against fleas and ticks for a full month.
What should I do if my dog vomits after taking NexGard?
If your dog vomits shortly after taking NexGard, contact your veterinarian. They may advise you to re-administer the medication or switch to an alternative flea and tick preventative.
Can I give NexGard to my pregnant or lactating dog?
