NexGard and HeartGard for Dogs
NexGard and HeartGard, manufactured by Boehringer Ingelheim, target different pests that may afflict dogs. NexGard is renowned for its potent efficacy against fleas and ticks, while HeartGard mainly prevents heartworms. They work hand in hand, each addressing unique issues that, when combined, provide a broad spectrum of protection for dogs.
NexGard: Flea and Tick Defender
NexGard is an oral medication that is a champion in the fight against fleas and ticks. Its active ingredient, Afoxolaner, interferes with the nervous system of these pests, leading to their death. NexGard’s swift action usually results in the extermination of fleas and ticks within 24 hours of ingestion. Notably, it’s also effective in controlling the Black-legged tick, Lone Star tick, and the American Dog tick, which are notorious for transmitting Lyme disease.
HeartGard: Shield Against Heartworms
HeartGard, on the other hand, uses Ivermectin and Pyrantel as active ingredients. These compounds are effective in preventing heartworm disease, a potentially fatal condition for dogs. HeartGard also helps in controlling and treating other parasitic infestations like roundworms and hookworms, enhancing its value in a comprehensive parasite control program.
Can You Give NexGard and HeartGard Together?
Given that NexGard and HeartGard each target different parasites, administering them together should not pose a problem. However, for first-time users, it’s advisable to stagger their introduction by a few days. This approach allows pet owners to discern which drug may be responsible should any adverse reaction occur.
Examining the Efficacy of NexGard and HeartGard
In their respective roles, NexGard and HeartGard have proven to be highly effective. NexGard’s key ingredient, Afoxolaner, is fast-acting, eliminating fleas and ticks within 24 hours of administration. Not only does it kill adult fleas, preventing them from laying eggs, but it also proves lethal to various tick species, including those responsible for transmitting Lyme disease.
HeartGard, with its dual active components of Ivermectin and Pyrantel, shields canines from heartworm disease, a serious and potentially lethal condition. Beyond heartworm prevention, this medication also controls and treats infestations of roundworms and hookworms, contributing to broader parasite control.
Optimal Administration of NexGard and HeartGard
While NexGard and HeartGard serve distinct purposes, they complement each other in a holistic approach to parasitic prevention. Both are designed for monthly administration, making it convenient for pet owners to establish a regular care routine. It’s also worth noting that both products come as tasty chews, easing the process of getting your furry friend to take their medication.
When introducing these medications for the first time, it’s advisable to administer them separately, with a couple of days in between. This strategy helps you identify the source should your pet exhibit any adverse reactions. It’s worth noting that reactions are rare, with the majority of dogs tolerating these medications well.
Possible Side Effects and Precautions
As with any medication, it’s essential to be aware of potential side effects associated with NexGard and HeartGard. While these medications are generally well-tolerated, some dogs may experience gastrointestinal upset such as vomiting or diarrhea. Less common side effects for NexGard include itching, lethargy, and lack of appetite, while HeartGard might cause tremors and dilated pupils in rare cases.
Always consult with your veterinarian if you notice any unusual behavior or adverse reactions after administration. Additionally, these medications should be used with caution in dogs with a history of seizures or other neurological conditions.
Embracing the Dual Defense
NexGard and HeartGard form a formidable duo in defending against the common threats of fleas, ticks, and heartworms. Their different active ingredients work in tandem to ensure your furry friend is well-protected. As you navigate your dog’s health routine, remember that these medications are tools to help maintain their health and happiness. Your vet remains your best ally in tailoring the right parasite prevention strategy for your dog.
Cost-Effective Alternatives and Buying Tips
For pet parents seeking alternatives to NexGard and HeartGard due to cost or other concerns, other brands offer similar protections. Simparica Trio is one such example, which covers fleas, ticks, and heartworms, potentially coming out cheaper than the combination of NexGard and HeartGard.
Remember, purchasing from reliable sources is crucial to avoid counterfeit products. Online pet supply stores like Chewy, or bulk retailers like Costco, often provide these medications at competitive prices. However, they will require a prescription from a vet, which usually necessitates a recent heartworm test.

Additionally, dogs should be tested for existing heartworm infection before starting on HeartGard.

In the case of HeartGard, side effects are rare but could include vomiting, diarrhea, and lack of appetite. In the case of an overdose, or if a dog ingests HeartGard not intended for its weight class, symptoms could include dilated pupils, stumbling, tremors, or drooling.
Remember, while these side effects can occur, they are not common and these medications are considered safe for most dogs. Always monitor your dog after administration and report any concerns to your vet.
Is there a Weight Requirement for NexGard and HeartGard?
Yes, there are weight requirements for both NexGard and HeartGard. NexGard is suitable for dogs that are at least eight weeks old and weigh at least four pounds. HeartGard, on the other hand, is safe for puppies as young as six weeks, with no minimum weight requirement.
These medications come in different dosages based on weight classes to ensure your dog gets the correct amount. It’s essential to choose the right product for your dog’s current weight to ensure effectiveness and safety.
Can I Use NexGard or HeartGard if my Dog is on a Special Diet?
Yes, NexGard and HeartGard are not known to interact with any specific dog diets. Whether your dog is on a weight management plan, a hypoallergenic diet, or any other specialized dietary regimen, it should still be safe to administer these medications. However, if your dog has food allergies, particularly to beef, it’s best to discuss this with your vet, as both products are beef-flavored.
What if my Dog Spits Out the NexGard or HeartGard Chew?
If your dog spits out the chew, you can try to offer it again. Some pet owners find it helpful to hide the chew in a treat or a small amount of food. If your dog consistently refuses the chew, contact your vet for advice. There may be other formulations or brands that your pet finds more palatable.
What Happens if my Dog is Exposed to Ticks or Mosquitos Before NexGard or HeartGard Takes Effect?
While NexGard starts killing fleas within four hours and ticks within 12 hours, there is a brief window where exposure could occur. Similarly, HeartGard is designed to kill the larvae of the heartworms that your dog was exposed to in the preceding month, it does not prevent the immediate bite from mosquitos. If you live in a high-risk area for ticks or mosquitos, discuss additional protective measures with your vet. Regular checks for ticks and using mosquito deterrents can add extra layers of protection.
