There are many joys of having a dog part of your life.
However, fleas and ticks are not amongst them.
Fleas and ticks are prevalent parasites found almost anywhere you go outside. Your dog only needs to brush up against the tree or roll around in the grass to pick up fleas and ticks.
The good news is there is an abundance of great products and treatments available on the market to help eliminate the risk of your dog getting infested with fleas and ticks.
Our article, Seresto vs NexGard, compares two excellent flea and tick products to help dog parents make an informed decision on which one is best for their pup.
I believe both products have their benefits; if I had to pick just one, it would be NexGard.
I recommend it because first, I’ve used it and know that it’s safe and effective even with younger puppies.
And second, because it is useful for treating more than just fleas and ticks.
Seresto – Collar
- Active Ingredients: Imidacloprid and Flumethrin
- Type: Collar
- Duration: 8 Months
Seresto is one of Bayer’s flea and tick products. It was launched in 2011 and is effective at both killing and repelling these parasites.
Bayer Animal Health is a globally recognized company that has been in business since 1919.
The Seresto collar is made from a polymer matrix and manufactured with insecticides that last up to 8 months.
The pesticides are slowly released into the dog’s skin then spreads over their entire body.
Flea and ticks are not the only things Seresto kills; it also takes care of biting lice and sarcoptic mange.
And, Seresto interrupts the flea life stages from egg to adult.

Seresto collars work pretty fast when it comes to killing parasites, and takes care of fleas within twenty-four hours and ticks within forty-eight hours.
Caution should be exercised on the first day your dog wears the Seresto collar since it is at its greatest potency.
It is advised children and other pets stay clear of the collar for at least a full day after attaching the Seresto collar. However, it is never recommended that children or other pets come in contact with the collar.

NexGard – Chewable Pills
- Active Ingredients: Afoxolaner
- Type: Chewable Tablet
- Duration: 1 Month
NexGard is a Boehringer Ingelheim Group product.
Boehringer Ingelheim Group’s focus is on improving the quality of life of humans and animals. They are a family-owned global company.
Ultimately, Afoxolaner attacks the central nervous system, causing the parasite to become overstimulated, killing the flea.
Because the nervous systems are different in dogs, afoxolaner should not affect the dog.
NexGard effectively kills adult fleas, mites, and various tick species like Lone Star ticks, American dog ticks, Black-legged ticks, and Brown dog ticks.
Additionally, NexGard works to rid dogs of Demodex mites responsible for demodectic mange, Sarcoptes mites that are the cause of sarcoptic mange, and Otodectes mites or ear mites.
NexGard does not repel or prevent fleas, ticks, or mites.
For NexGard to work, the parasite must bite your pup and ingest the poison to kill it.
NexGard starts killing fleas in as little as four hours after your dog consumes the chewable, and 48 hours for ticks.

Seresto lasts between 6-8 months, and NexGard lasts one month.
Seresto lasts a lot longer, works as a preventative as well as managing fleas and ticks, while NexGard kills three different types of mites and is easy to administer.
I am partial to chewable flea and tick products over collars.
I think flea and tick collars are great, but they are not my first choice, mainly because I have a multi-pet household and because my dogs are allowed on the furniture.
That being said, Seresto is the best choice in some situations.
Use Seresto if:
- Your dog is prone to seizures
- You have a single dog household with older kids
- You are looking for an effective economical flea and tick option
Use NexGard if:
- You have a multi-dog household, or have young children who may come in contact with your dog’s collar
- Your dog currently has fleas
- Your dog has issues with mites
Overall, both products are excellent choices for protecting against fleas and ticks, yet when choosing between Seresto vs NexGard, a lot depends on your dog and lifestyle.
Can You Use Seresto and Nexgard Together?
Yes, the two products are effective when used together.
Though they are considered safe to use together, it is always best to check with your vet first.
