6 Best Flea Collars for Dogs – Reviewed – World Animal Foundation

When my cockapoo named mozzie (pronounced ozzy with an m in front of it) was about a year old, I took him to the vet for a checkup. he surprised me when they found out he had fleas.

I had been faithful to applying topical treatments every month as recommended. but apparently, the topical treatment he was using was not waterproof and washed off when I bathed him.

I’ve been a bit paranoid about fleas ever since.

I check his coat regularly to make sure it hasn’t attracted fleas, which could make him uncomfortable or harm his health. He is my baby and I do everything I can to protect him!

While vets recommend more topical and oral flea treatments, a flea collar can offer your dog an extra line of protection if he spends most of his time outdoors or will be in areas where he is likely to come into contact with fleas. contact with fleas and ticks.

Some flea collars also offer protection against mosquitoes, lice or other pests.

                          here is a list of factors worth considering before choosing a flea and tick repellent collar for your canine companion.


                          flea collars use different combinations of chemicals or natural oils.

                          some common chemical ingredients that are generally considered safe include:

                          • deltamethrin
                          • amitraz
                          • pyriproxyfen
                          • propoxur
                          • tetrachlorvinphos (tcvp) is also relatively common in flea collars, although it is a more controversial ingredient. some scientists believe it is a human carcinogen and possibly a neurotoxin to people and pets.

                            Occasionally, dogs have skin reactions from the chemicals in flea collars. if that happens, you can learn how to treat a chemical burn from a flea collar and treat it at home.

                            Natural ways to kill fleas and ticks include the use of essential oils. skin irritation is much less likely with a natural collar, though not impossible.


                            Each of the flea collars lasts a different amount of time, from 4 months to a full year.

                            Keep in mind that if your dog likes to go swimming or if you keep the flea collar on during baths, this may reduce the amount of time the collar can repel fleas.

                            While it’s so nice not to have to worry about giving your dog monthly flea and tick prevention, you might as well forget about changing his flea and tick collar at the right time.

                            one way to remember when it’s time to change the collar is to set up a recurring delivery with amazon.

                            odor vs odorless

                            Most flea collars that use chemical ingredients are odorless, though it’s always best to check the product description to be sure.

                            with natural flea and tick collar, works with scented essential oils. depending on the combination of oils used, you may love or hate the scent.

                            If you’re shopping for a natural flea collar, be sure to read the ingredient list to see if you like the smell of used oils. some common scents are:

                            • Citronella

                            • frequently asked questions

                              how do flea collars work?

                              When you get a new flea collar, you’ll stretch it to activate it. then you will place it securely around your dog’s neck and adjust it. make sure it’s not too tight or too loose.

                              Then, trim off any excess material. if you have a puppy, don’t trim the excess too much. you may need to adjust the puppy collar over time as your dog grows.

                              once the collar is on your dog, the ingredients will begin to distribute evenly throughout the skin and coat.

                              depending on the ingredients, the flea and tick collar will repel, treat or both.

                              a repellent collar emits gas to keep pests away from your pup.

                              flea collars work by killing pests when they bite your dog or when they come in contact before they can bite.

                              Are flea collars safe?

                              flea collars for dogs are a somewhat controversial topic. while they are known to be quite effective, they do have some drawbacks.

                              The chemicals used in a flea collar work by direct contact. this means that every time your dog rubs up against you or your furniture, some of those chemicals could be transferred.

                              It is recommended that you wash your hands after handling your dog if he is wearing a flea collar. It is also not recommended that you sleep in the same bed as your dog if he wears a flea collar.

                              Skin irritation may occur from the chemicals used. If your dog is going to have an adverse reaction to wearing a flea and tick collar, it will likely happen within the first few days after it is put on.

                              That being said, pet owners have used flea collars for decades to repel fleas and ticks. talk to your vet if you have concerns about whether a flea and tick repellent collar is the best option for your pup.

                              Do flea collars kill fleas instantly?

                              flea collars do not kill fleas instantly.

                              It may take a few days before you kill fleas all over your dog’s body because you have to wait for the active ingredients to be distributed from the collar to the tail.

                              depending on the collar, it may only kill adult fleas and ticks, or it may also kill flea eggs and larvae.


                              Fleas and ticks can cause more than just itching and irritation for your pup. bites can lead to anemia, lyme disease, and other health problems.

                              pet owners should always try to keep their dogs protected from these dangers. luckily, the solutions are quite affordable and you don’t even need a prescription from your vet.

                              I hope this article has helped you understand the ins and outs of buying a flea and tick collar for your dog.
