1. Create essential oils to treat dog fleas
This is a traditional home remedy for treating dog fleas that has proven quite effective. First, you'll need fresh citrus peels and a bit of water. Place everything in a small pot and simmer over medium heat for about 15 minutes to fully extract the essential oils from the citrus peels.
Once cooled, pour the mixture into a spray bottle. Simply spray it on your dog 2-3 times a day to treat the fleas. Although the treatment takes time (1 to 2 months), it delivers excellent results and the essential oils will make your beloved dog feel comfortable and at ease. Give it a try!


2. Remove fleas daily
This is one of the most traditional methods. All you need is to dedicate a little bit of time each day to remove and eliminate those annoying fleas, which will save you a lot of money.
However, not all dogs are on board with this approach. Fleas often gather around the paws and ears, but many dogs are quite sensitive and won't tolerate having these areas touched. If you try to force flea removal in these spots, your dog may become frightened or even bite you. This method is also not ideal for people who are afraid of fleas or those with busy schedules filled with work or studies.


3. Use medication
This method is very effective and saves time, but it can be quite expensive, as each flea treatment injection costs between 200,000 VND to 300,000 VND. You just need to take your dog for regular injections every 6 months to prevent and treat fleas. Of course, some dogs don’t like injections, so you can ask the vet for a spray treatment instead.
The price of each spray bottle ranges from 100,000 VND to 200,000 VND depending on its effectiveness. While the medication is on your dog’s fur and skin, make sure not to let your dog lick it, as some products may contain ingredients that could harm your pet's health.


4. Bathe your dog with morning glory leaves
Morning glory leaves are slimy, making them quite effective for treating fleas. Simply boil the leaves with some water, let it cool, and bathe your dog with this solution. Keep the mixture on your dog for about 3-4 hours. Fleas won't be able to cling to your dog due to the slimy nature of the leaves.
Afterward, give your dog another bath to wash away the slimy residue and any remaining fleas. This method is rarely used because it only works for fleas and requires quite a bit of time and effort. So, use this method only when you've run out of other options.


5. DIY flea collar
You can make your own flea collar for your dog without the need to spray or rub it with flea repellent solutions. You can buy or create a simple collar, then dilute a few drops of lavender or cedarwood oil in water and apply it directly to the collar.
Few people know that vodka can also be effective for treating fleas on dogs. Purchase or create a simple collar, then soak it in a teaspoon of unscented vodka and let it dry. You can also add a few drops of essential oil to the vodka for a pleasant scent, though some dogs may not like the fragrance of the oils, so you could skip them if needed.


6. Flea comb
If you've purchased a flea comb from a pet store, you can use it without the need to buy additional products. This flea comb is free of chemicals but is specially designed to remove fleas and their eggs from your dog's fur.
If your dog is infested with fleas, the flea comb will become your best ally in the fight against them. The comb can effectively remove fleas from your dog's coat. Brush your dog from head to tail, making sure to brush down to the skin. If you only comb the outer fur without reaching the skin, some fleas may remain after combing. After catching the fleas, place the comb in a bucket of soapy warm water to quickly kill them.


7. Treating Fleas by Keeping Your Dog's Living Area Clean
Fleas, or their eggs, are often found in places where your dog frequently rests, such as their bed. Fleas tend to hide in these areas and may leave their eggs behind. If your dog is currently infested with fleas, it's best to prevent them from jumping onto furniture or into common living spaces.
Maintaining cleanliness will eliminate the best conditions for fleas to breed and thrive. While it may not be the most direct method, it is an effective way to combat fleas. Never overlook this detail—always clean and dry your dog's belongings, such as their bed, rugs, and toys, using a hairdryer. High temperatures help prevent dampness, which can create an ideal breeding ground for fleas.


8. Avoid Letting Your Dog Roam in Dense Areas
You should be aware that the life cycle of fleas is similar to that of mosquitoes. Female fleas lay their eggs in tall, dense grass. When the eggs hatch into flea larvae, they cling to the grass and wait for a host to pass by, attaching to it to feed on blood.
Therefore, when taking your furry companions for walks, make sure to avoid areas with thick and tall grass to prevent flea larvae from attaching to your dog's body. Regularly trim the grass, tidy up the yard, and consider planting plants with scents that fleas dislike, such as citronella or mint, in your garden.


9. Limit your dog's interactions with other dogs suspected of having fleas
Fleas are easily transmitted because they have 6 to 8 legs and can crawl quite fast. If a dog plays and roughhouses with other dogs, the friction between them can unknowingly spread the fleas.
This may sound simple, but it's quite difficult to enforce since you can't always control when your dog is playing and especially because it’s hard to tell if other dogs are infested with fleas. If a dog isn't infected and you prevent them from playing, your dog may feel left out and lonely without its friends.


10. Bathe your dog regularly
Bathing is one of the most traditional methods to prevent dog fleas, and it also helps keep your dog clean and smelling fresh. However, some pet owners still don’t know how to bathe their dogs correctly. You should be aware that if bathing is done incorrectly, the chances of flea infestation remain the same. Therefore, you should: Bathe your dog in a specific order: head, body, then legs. The head is a sensitive area, and a dog’s ears are a common place where fleas may lay eggs since they can't scratch deep inside. If you bathe the body first, fleas may move to the head, making the bath ineffective.
- Use dog shampoo specifically designed for dogs. The skin of dogs and humans are very different. Be sure not to use shampoos that might cause allergic reactions or skin issues for your dog.
- Limit baths to 3–4 times a week.
- Avoid bathing your dog in cold weather to prevent them from getting sick.
- After bathing, dry your dog’s body and ears to prevent discomfort caused by cold or water trapped in the ears.
