Dog Fleas: A short description

Among all the species of flea, the dog flea is one kind, which lives as an ectoparasite mainly on dog and cat. Its scientific name is Ctenocephalides canisIt is a tiny, dark brown insect, which stays within 65-80°F of temperature and 75-85% humidity levels. These parasites live on the blood of dogs, cats, and even humans. The dog flea can cause Dipylidium caninum.

They can stay alive without food for a few months. However, female fleas need to suck blood to produce eggs. As soon as they take shelter on a host, they lay around 4000 eggs as a whole. The life cycle of flea consists of four phases – egg, larva, pupae, and adult flea. Cycle completion requires several weeks to months. The preferable temperature of this cycle lies between 70°-85°F and needs around 70% level of humidity.

How to check the signs and symptoms of dog fleas 

How do you check your dog for fleas? There are some signs and symptoms for dog fleas, which will help you to identify the severity of this problem. Dogs become infected with fleas when they get in touch with other pets. Fleas can attack directly from their surroundings. 

From the previous point, we have learned about the life cycle of dog fleas. In the third stage, pupae remain under the protective layer of the cocoon. The adult flea waits for several weeks to months to come out of the cocoon. It emerges only when there is a suitable host. It depends on vibrations, carbon dioxide levels, and body temperature of the host. Now, it is time to verify if your dog has fleabites. 

Checking dog for fleas

  • The existence of flea dirt on the dog’s skin, bed, or home means fleas have already attacked him. Flea dirt or flea poop has the size of the pepper. Brush your dog’s skin gently by placing a wet paper towel underneath. If there is a red circular line around the black blemishes on the towel, then these are flea dirt. 
  • Use a flea comb to check for them. A flea comb can be the perfect tool to get rid of fleas and flea eggs. These combs are designed especially for this purpose. We recommend Safari Dog Flea Comb with Double Row of Teeth. It comes with a special double row design, which helps to spot fleas or dry skin instantly. However, you should take proper care while using it. Otherwise, it may hurt the skin of your pet. 
  • Your pet’s bath time is another scope to identify dog fleas. If you drain properly, fleas will fall into the water. Besides, if you notice small blood spots in the water, it is actually the flea dirt. 

Symptoms for dog fleas 

The main symptoms of fleabites include – 

  • Scratching
  • Licking
  • Hot spots over the body
  • Hair loss
  • Inflammation
  • Minor skin infections

In severe cases of infections, blood loss and anemia can happen. If your pet is oversensitive to flea saliva, even a single bite can cause itching of the whole body. 

How to keep away dog fleas 

You may now want to get rid of these dog fleas badly. In this section, we will discuss the treatment, prevention, and some natural remedies for this problem. 


You may need to talk about the flea issue with your Veterinarian. The prescription may contain an oral flea killer or a flea shampoo. In case of urgency, apply for the medicine immediately.

Flea killers

Flea killers like Capstar Fast-Acting Oral Flea Treatment start killing fleas within 30 minutes after the first dose. Follow the instruction properly before giving your dog a dose. It is a safe oral pill, but stop using if any irritation occurs. 

Flea-killing shampoo 

After 6/7 days of this treatment, use flea-killing shampoo on the skin of your pet. A little amount is enough. Avoid overusing as this can dry out the dog’s skin. Wait for more or less 10 minutes before washing it off. It can also do the work of a primary medicine for dog fleas. 

Spot-on flea treatments

If you use spot-on flea treatment, you should avoid giving a bath to your pet for at least 4/5 days. Since spot-on treatments transfer into the subcutaneous fat layer of the pet’s skin, the skin layer becomes hostile to fleas and their larvae. If you give them a bath in that condition, this may wash away the medication and hamper the effectiveness. Be aware of using it along with oral preventives, as this can have some side effects.

  • Flea control sprays need to be sprayed on all body parts of the pet. Use a clean, soft cloth or cotton balls to apply to sensitive areas like eyes and ears. Make sure that it does not reach inside the eyes and mouth. Do this in a well-ventilated space. 
  • Do not use any sprays or dips without your Veterinarian’s advice. Also, follow the instructions from the manufacturers. 


To prevent all possible flea attacks from your house, some preventive and after measure will do well. If your dog is already affected with dog fleas, then you should take proper care of the hygiene. Additionally, if there is not any sign yet, but you want to be on a safe side, the following tips will be a great help to you too.

  • At first, make the best use of your knowledge on the flea life cycle. You already know that it depends on accurate temperatures and humidity levels. Therefore, you can ensure the quick appearance of the pupae with a humidifier. In addition, you should adjust the room temperature. After the emergence of all, destroy it. A humidity level below 50% and temperatures over 95 °F can eradicate flea larvae.
  • Cleaning thoroughly the pet beds, carpets and furniture are required to get rid of flea eggs, larvae, and pupae. Use hot water with soap to clean your dog’s toys. After the completion of a clean-up event, do not forget to throw away the vacuum bags. Flea eggs can also grow inside a vacuum bag, so make sure you dispose of it properly. According to a report of Texas A&M University’s Extension Office, vacuuming can remove almost 30% of the larvae and 60% of flea eggs from a carpet and reduce their food supply. 
  • In case of selecting a pesticide, check the ingredient list first. Chemicals like pyriproxyfen or methoprene work as an active factor for flea larvae –killing. Always read the precautionary labels. It may contain some harmful and toxic chemicals. Alternatively, you can ask for a specialized team of exterminators. They have a better knowledge of chemicals.

Salt and baking soda both work as dehydration agent. It helps to remove adult fleas, especially. For this process, spray baking soda or salt on the carpet. Wash the baking soda by rubbing it with a brush. On the other hand, leave the salt for 24-48 hours. Then clean the place properly.

Diatomaceous Earth

This powder-like earth is the fossilized relics of miniature, aquatic organisms called diatoms. It has dehydrated and non- toxic properties. Normally sprinkle it on to the over flea engages areas. Leave it for a few hours or even a day, then vacuum swiftly. In addition, follow the other preventive measures as well. Try to use the food-grade version of diatomaceous earth. Besides, use a mask, as the spray can bother your eyes and breathing. 

Dog fleas on humans

Humans can get infections from dog fleas. It mainly happens because of the close connection to your pets. Their body works as the bearer of fleas. However, fleas are mainly dangerous for your pets. Fleas prefer dark, damp, and furry environments, just like the dog’s skin. On human skin, they are more visible, so they cannot grow rapidly.  

Fleas bite on the ankles, hands, or lower legs normally. The skin can itch if you have an allergy to fleas. If there are small reddish rashes on these areas of your skin, you may be a victim of fleabites.

Nevertheless, the treatment is usually simple, and there is nothing to worry about. Use antibacterial soap to wash the affected area. It will decrease the itchiness and probability of infections. You can apply anti-itch cream for skin. Hydrocortisone, Aloe Vera gel, and calamine lotions are some popular solutions for insect bites. Avoid scratching the affected skin; otherwise, it will enhance the risk of infections. You need to remember that flea prevention commodities are not meant to be used on the human body.
