Best Flea Medicine for Dogs (without a Vet Prescription): Winners
My dad travels with his dog, Clyde, especially to get away from Minnesota winters.
Recently they headed south to warmer areas, but this time my dad forgot to grab Clyde’s flea medicine.
Clyde was due to get his flea preventative later in the week, but they would still be on vacation, so my dad reached out to ask me if I knew of any non-prescription
flea medicine he could buy while on vacation.
I sent him a few suggestions for the best flea medicine for dogs without a vet prescription.
Thankfully he had no problems finding what he needed, and Clyde didn’t miss his flea treatment.

Seresto is a Bayer flea and tick product that has been an effective flea medicine since 2011 [. 1]
Seresto collar kills and prevents fleas. Plus, it interrupts the flea life cycle, so you don’t have to worry about re-infestation.

The Seresto collar works fast and will start killing fleas within 24 hours and will continue to work for up to 8 months.

Seresto is generally considered a safe product; however, all flea medicine comes with risks.
Seresto’s most common side-effect is skin irritation around the neck. Other side effects include:
Rashes Itching Excessive drooling Shaking Vomiting Decreased appetite Sleepiness or lethargy Hairloss
Seresto is not ideal for dogs living in households with young children who might come in frequent contact with the flea collar.
What I like best about Seresto is that it
kills on contact, and you don’t have to worry that your dog will be bit by fleas for the medicine to work.

Kills on contact Does not effect your dog’s nervous system Repels fleas Effective against multiple parasites
Not fully waterproof, so it may only be active for 6 months if your dog likes to swim May cause skin irritation to others in the household if they come in direct contact with the collar
Seresto is an excellent economical choice since it costs an average of just over $4 per month.
Also, since Seresto lasts up to 8-months, you don’t have to deal with flea treatments every month, making it truly the
best flea collar without the need for a prescription.

Over the counter (OTC) flea pills kill fleas but do not act as an ongoing preventative.

Prescription oral flea medication often treats more than just fleas. It also uses more harmful types of chemicals, requiring stricter regulations.
