What are flea collars and how do they work?
Flea collars contain insecticides that kill fleas and ticks on contact and provide continuous protection against these parasites. According to Petcarerx, flea collars work by “emitting a flea fighting drug into the sebaceous glands and hair follicles of your pet’s neck and upper back.”
The insecticides are slowly released from the collar over several months, spreading over the pet’s coat and skin. As fleas and ticks jump on or bite the pet, they come into contact with the insecticides and are killed.
Some of the common insecticides used in flea collars include propoxur, tetrachlorvinphos, and imidacloprid. These insecticides are toxic to fleas and ticks but safe for pets when used as directed.
Flea collars can provide continuous protection for pets for 5-8 months. They are an effective, convenient, and low-maintenance option for flea and tick control compared to monthly topical treatments.

Do I need to bathe my dog before applying a flea collar?
In most cases, you do not need to bathe your dog before putting on a flea collar. Flea collars contain insecticides that spread across your dog’s coat to kill fleas and ticks. These insecticides bind to the natural oils in your dog’s skin and fur, so bathing right before application can wash away some of the active ingredient.
According to experts, bathing before applying a flea collar is only recommended if your dog has a heavy flea infestation. The bath can help wash away some of the live fleas before starting flea prevention (source). Otherwise, your dog should be bathed and completely dry before putting on the flea collar.
Bathing too soon after application may also reduce the effectiveness of some flea collars. It’s best to wait at least 48 hours after putting on the collar to bathe your dog. This gives the insecticide time to absorb into your dog’s oils and coat, where it will be waterproof (source).
In summary, you typically don’t need to bathe your dog before applying a flea collar. Only bathe first if your dog has a major flea infestation. Otherwise, make sure your dog is clean and dry before putting on the collar, then wait 48 hours before the next bath.
When is the best time to put on a flea collar?
The best time to put on a flea collar is at the beginning of flea season for preventative care. Flea season often starts in spring and lasts through fall in many parts of the country, when the weather warms up and there are higher humidity levels that allow fleas to thrive. According to the American Kennel Club, flea populations peak from July to August in most regions 1.
By putting on a flea collar ahead of peak flea season, you can help protect your dog against flea infestations before they start. Flea collars work by releasing small amounts of insecticide onto your dog’s fur to repel and kill fleas over time. It’s best to get the preventative coverage started before fleas become widespread and have a chance to hop onto your dog.
Be sure to check the package directions for your specific flea collar brand, as some may recommend application at the very start of flea season, while others may suggest putting it on a few weeks ahead. Reapply the flea collar per the timeline instructions on the label, which is usually every 3-8 months.
Consistent flea prevention is key to keeping your dog protected during flea season. In addition to replacing flea collars as directed, also check with your veterinarian about monthly flea and tick preventatives that can work alongside a collar for comprehensive protection.
Using flea collars safely and effectively
Flea collars can be very effective at preventing and treating flea infestations when used properly. Here are some tips for using flea collars safely and effectively:
Buy the right size collar for your dog. Make sure to follow the weight guidelines on the packaging. You should be able to fit two fingers between the collar and your dog’s neck. Having a properly fitted collar will allow for consistent contact with your dog’s skin and coat.
Monitor your dog closely after first applying the flea collar. Some dogs may have skin reactions or other side effects. Redness, scratching or head shaking could indicate an allergy. Discontinue use if you notice any abnormal symptoms.
Don’t overuse flea collars. Follow the manufacturer’s recommendations for how often to replace the collar. Overusing the same collar can lead to skin irritation. Rotating between different flea prevention products is ideal.
Properly dispose of used flea collars by placing them in securely sealed plastic bags. Flea collar ingredients can be toxic to people and pets if ingested (Orlando Sentinel, 2023). Keep both used and unused collars out of reach of children.
Are flea collars safe for dogs?
Flea collars are generally safe for dogs if used properly, but there is some potential for skin irritation. According to the NRDC, flea collars can contain dangerous insecticides like tetrachlorvinphos, carbaryl, and propoxur which can be absorbed through the skin, so owners should take precautions.
The American Kennel Club recommends not using flea collars on puppies under 12 weeks as their skin is more sensitive. It’s also important to monitor the collar area for any signs of irritation and remove the collar if this occurs. Trimming hair around the collar can help prevent irritation.
Overall, as long as label directions are followed carefully and dogs are monitored, flea collars can be a safe option for adult dogs in need of flea prevention. However, other alternatives may be preferable for puppies or dogs with sensitivities.

Natural alternatives to flea collars
If you want to avoid chemical flea treatments, there are some natural options that can help repel fleas from your dog. Some popular natural alternatives include:
Essential oils – Oils like citronella, eucalyptus, peppermint, tea tree, and rosemary can act as natural flea repellents. Add a few drops of these oils to your dog’s shampoo or dilute and spray directly onto their coat. Be cautious using essential oils on dogs, as some oils can be toxic to them in high concentrations.
Apple cider vinegar – Apple cider vinegar makes the skin more acidic, which fleas don’t like. Mix 1 part apple cider vinegar with 1 part water in a spray bottle and lightly mist your dog’s coat (Source). You can also rub diluted apple cider vinegar into your dog’s fur with a washcloth.
Herbal flea spray – Make a natural flea repellent spray by steeping herbs like rosemary, lavender, mint, or rue in hot water. Strain the mixture and combine it with witch hazel or apple cider vinegar in a spray bottle. Spritz onto your dog’s coat.
Diatomaceous earth – This powder contains tiny fossilized remains of algae that can penetrate fleas’ exoskeletons and kill them. Sprinkle food-grade diatomaceous earth into your dog’s fur and brush it in. Avoid getting it in their eyes.
Always monitor your dog closely when using natural flea remedies to ensure they don’t develop any adverse reactions.
Other flea prevention methods
In addition to flea collars, there are other ways to help prevent flea infestations on your dog. Some popular alternatives include:
Oral/topical treatments – Oral tablets or topical spot treatments with ingredients like lufenuron, nitenpyram, or spinosad can kill fleas and prevent infestations. Some popular brands include Nexgard, Bravecto, and Simparica.
Flea combs – Regularly combing your dog with a fine-toothed flea comb can help remove fleas and eggs. Look for flea combs made specifically for dogs.
Washing bedding – Frequently wash your dog’s bedding using hot, soapy water to kill any fleas or eggs hiding out.
Vacuuming – Thoroughly vacuum carpets, furniture, and floors to suck up fleas and eggs and dispose of the vacuum contents right away.
Yard sprays – Use sprays containing insect growth regulators in your yard to kill flea eggs and prevent reinfestation.
Combining multiple flea prevention methods can help provide the best protection against fleas without relying solely on flea collars, which may cause skin irritation in some dogs.

Signs of flea allergy dermatitis
Flea allergy dermatitis is an allergic reaction to flea bites. Dogs with flea allergy dermatitis develop severe itching, redness, and irritation from the flea’s saliva. Common signs of flea allergy dermatitis in dogs include:
- Itching – Excessive scratching, licking, chewing, and rubbing due to intense itching. The itching tends to start around the base of the tail and spread up the back.
- Redness – Red, irritated skin from repeated scratching and biting. The skin may look raw in patches.
- Hair loss – Patches of hair loss usually around the back, tail base, and hind legs from the dog’s biting and scratching. The skin may appear scabbed or crusty.
- Hot spots – Moist, red, irritated lesions created by repeated licking, chewing, and scratching of itchy skin. Hot spots can become infected.
- Biting and chewing – Dogs bite and chew at their skin constantly to relieve the itching caused by flea allergy dermatitis.
The itching and skin irritation from flea allergy dermatitis is extremely uncomfortable for dogs. It’s important to treat the condition to ease your dog’s suffering. See your veterinarian if your dog develops signs of flea allergy dermatitis for proper diagnosis and treatment.

When to see a vet about fleas
Fleas can be a nuisance, but in most cases you can handle an infestation at home with over-the-counter treatments. However, you should make an appointment with your veterinarian if:
- The infestation persists despite using flea control products as directed
- Your dog develops signs of a skin infection like redness, scabs, or hair loss from excessive biting and scratching
- You notice signs of anemia such as pale gums, weakness, or rapid breathing
- Your dog has tapeworms, which can be transmitted by ingesting fleas. You may see rice-like segments around your dog’s hindquarters.
Veterinarians have prescription flea control products that are stronger and work faster than OTC options. They can also provide medication to kill tapeworms and treat any secondary skin infections caused by flea allergy dermatitis. Getting severe flea infestations under control quickly is important to relieve your dog’s discomfort and prevent ongoing health issues.

Flea prevention is key
The best flea prevention for dogs is being proactive and stopping infestations before they start. Consistent use of flea and tick control products should be a priority year-round, not just in summer. Some parasites like fleas can thrive in warm environments even in the winter. Being diligent about prevention will minimize the chances of dealing with a major infestation. According to VCA Animal Hospitals, “Most [flea and tick] products are designed to be used at monthly intervals throughout the year, beginning at about 2 to 3 months of age.”
It’s also important to monitor your dog closely when they are outside or exposed to other animals. Do frequent checks in their coat to look for signs of fleas or ticks. Catching an infestation early makes treatment easier. The American Veterinary Medical Association recommends using flea and tick prevention as directed, and routinely checking your pet and home for signs of fleas or ticks.
