With a multitude of flea and tick preventatives on the market, it is hard to know which one is the best choice, especially when they come in a variety of forms.
As dog parents, we want to keep our dogs safe from parasites, but we also need to find a product we feel confident is safe for our dogs.
Living in tick country, it is a challenge to know which products are the best choice for my dogs.
As it turns out in my household, there isn’t just one product used by all four of the dogs.
Between all four dogs, I use three different products.
My goal for writing this article is to compare Seresto vs Bravecto vs Frontline in one place to make it easier for dog parents to choose the one that is best for their pup.
Though all of these products are great, not all will work for everyone.
Whereas, Frontline Plus is relatively safe to use, especially for dogs like Sophie, who is a bit older and have several medical conditions.
And finally, Bravecto is an excellent choice since it lasts three months at a time.
Seresto vs Frontline Plus vs Bravecto
Seresto – Collar
- Active Ingredients: Imidacloprid and Flumethrin
- Type: Collar
- Duration: 8 Months
Seresto is a Bayer product that launched in 2011. Seresto is an effective flea and tick collar that both kills and repels these parasites.
The collar is made from a polymer matrix which has been infused with insecticides that lasts up to 8 months.
The pesticides are slowly released into the skin then spreads over the body of the dog.
In addition to taking care of fleas and ticks, Seresto also kills biting lice and helps with treating with sarcoptic mange.
Plus, Seresto takes care of all flea life stages from larvae to adult.

The collar is most potent the first day you put it on your dog, so it is advised you keep children away from your dog for a day after putting on the collar.
However, overall it is recommended to prevent children from playing with the Seresto collar.
Plus, puppies as young as seven weeks old can use Seresto.
One of the most significant drawbacks of Seresto is that it isn’t waterproof.
Dogs can be bathed and swim with the collar on; however, for dogs that enjoy time in the water or require more than one bath a month, they will need to have their collar replaced at five months instead of eight.

Frontline Plus – Topical

Based on the price per month and duration Seresto is the best choice, but the drawback is that people with children need to be sure the kids don’t have excessive contact with the collar.
Frontline Plus appears to be one of the safest choices with the fewest potential side effects.
Plus, it is waterproof after 24-hours.
However, it only lasts 30 days and requires monthly reapplication.
Bravecto is perfect for those looking for an easy three-month protection option that is waterproof, fast-acting, and covers for two types of mange and ear mites.
However, the two drawbacks with Bravecto is that it is the most expensive and requires a prescription.
If you choose Seresto, it lasts the longest of all three options, even if you need to change it out every five months instead of every eight.
Additionally, Seresto is the only one of these products that also repels ticks in addition to killing them.
And though the initial cost for Seresto may seem high, it is less than $10 per month if your dog wears it for eight months.
If you don’t mind applying Frontline every month, it is a proven reliable product that has few side effects.
Plus, Frontline is easy to use, and after 24 hours it is waterproof, so you don’t need to monitor how often your dog is swimming.
Bravecto kills the most parasites of any of these three options.
Plus, it is easy to administer, and you don’t need to worry about coming into contact with the product once you have applied or attached it.
Additionally, it is waterproof immediately and goes to work quickly.
Though Bravecto is a bit more expensive, it is often well worth it for the convenience and additional parasite coverage it offers.
All three are great products, though if I had to choose just one, I would say Bravecto for its ease of use and not needing to worry about coming in contact with it when petting or playing with my dogs.
But I also really like Frontline due to how safe a product it is, which is not something that can be said for Bravecto as it does have more significant and common side effects.
However, you will not go wrong with any of the three options, and you must choose the option that will work best for you and your pup to keep the flea and ticks away.
What is the safest flea and tick preventative?
Frontline, it not only deals with fleas and ticks but also kill biting lice.
Plus, if your dog licks the area of application to see what it is, it won’t harm your dog.
This does not mean that excessive licking or ingestion is safe, but it also isn’t so toxic you need to be overly concerned.
Is Seresto Safe to Handle?
According to the EPA, Seresto is safe for humans to handle though it can cause skin irritation.
Additionally, it is recommended to prevent kids from playing with the collars.
Does Bravecto Kill Other Parasites?
