Flea Bites On Dogs

​​Flea Bites On Dogs & Puppies

A red, itchy bite on a dog is caused, in most cases, by a flea. A flea is a parasite that bites and feeds on the blood of your dog. A flea will consume 15 times its body weight in blood daily. They will feed and then mate. Egg production will begin 24-48 hours after their very first meal.

For a flea to thrive there must be optimal environmental conditions. When the weather starts warm it becomes the time of year when everyone—including their pets—live outdoors. The synthesis of warmer weather, humidity and your dog’s blood are the perfect combinations for a flea thrive and lay their eggs.

Fleas are prolific reproducers. They breed quickly and often. The average female flea will lay 25-50 eggs per day for the duration of her life span. For an adult flea, that is 50-100 days. Thus, if you see one flea, there are at least a hundred or more fleas on your pet.

How To Know If your Dog Has Fleas

The most obvious signs of a flea infestation on your pet is excessive licking or scratching. You should take note of where your dog is licking or scratching. The fleas will most likely be gathering in those specific areas. The more fleas in those areas, the greater the chance of spotting them.  The common areas that fleas will congregate will be: the tail area, belly, head and neck. There may be dark specks (the flea feces), or white specks (flea eggs) in dog’s hair. Flea feces will be what is most noticeable in your dog’s hair.

Now that you know where to look, do you know what to look for?

What Do Flea Bites Look Like On Dogs?

Aside from the licking and scratching, there are other symptoms to take note of. Your dog could also be biting and chewing on their skin, legs, or feet. Thus the chewing, biting and scratching, causes irritation to the dog’s skin. There may be reddish looking fur in the affected areas. There may also be hot spots on the dogs head, chest, legs or hip from the excessive chewing.

Can Flea Bites Spread Disease To Dogs?

There are a few diseases that can be transmitted to your dog via a flea bite, or by ingestion of a flea while grooming.

Murine Typhus

Rickettsia typhi is the bacterial strain that causes Murine typhus. The bacterium is normally carried by rodents such as rats. It is transmitted to your dog via an infected flea or its feces. M. Typhus usually does not show outward symptoms. A vet will not test for typhus unless there is an outbreak of it in the human habitation of the dog. Then a simple blood test can determine if the dog has M. Typhus.

If typhus detected, the vet will treat the dog with a broad spectrum antibiotic, such as doxycycline. The medication can be taken orally or administered via intravenous injections. The duration of treatment can last 10 - 21 days. After which, routine preventative flea control should be set in motion.

Iron Deficiency Anemia

Anemia is a reduction of red blood cells due to prolonged blood loss. Anemia in dogs is most found in young dogs that have a severe infestation problem. Signs of anemia in an affected animal will include a loss of energy, some weakness, and a loss of appetite. Other symptoms may include pale gums, a heart murmur, increased heart rate. A veterinarian may check the animal for enlargement of the spleen.

Tapeworms

Most urban dogs and cats eat prepared foods and don’t have access to any natural prey. Such animals can still acquire dog tapeworm by ingesting fleas during grooming. Dogs residing in suburban or rural areas or are hunters have more of a possibility of getting a tapeworm by eating raw meat or being exposed to the offal of farm or wild animals. Once ingested, the tapeworm will grow to an adult and affect your dog's health. Tapeworms are treatable.

Other Flea Bite Complications

When a flea bites a dog it leaves behind some saliva. Some dogs are very sensitive to the saliva. This sensitivity is flea allergy dermatitis. It leads to extreme itchiness, irritated skin, hair loss and secondary skin infections. The irritated skin will look almost rash like. Do not mistake it for a rash.

A severe allergic reaction to a flea bite may also result in blisters on the skin. These blisters form around three days after the first initial flea bite. The fluid-filled blister will be translucent and surrounded by redness. Should the blistered skin die, it could take longer for the lesions to heal.

Secondary skin infections can manifest into oozing open lesions, skin abscesses, and pustules. These skin infections will heal in about four to six weeks. Yet the skin may remain discolored for a longer length of time.

Flea shampoos are very useful for killing adult fleas and removing feces and eggs still on your pet. Once thoroughly covered in the shampoo, let the shampoo sit. It can take up to ten minutes for the shampoo to kill the adult fleas. If your dog is one that does not tolerate bath time, then there other options, such as “leave-in” flea shampoos. It is important to follow the directions on the bottle for the shampoo to be effective.

A flea dip is another option that you may choose to treat your pet with. It is a concentrated chemical insecticide. The product is similar to shampoos. However, dips can be very toxic if you misuse them. That being said, in a well-ventilated area dilute the product with water. It is is very important that you dilute the product in water because of the strong concentration of the chemical. You can pour the liquid over the dog’s back or you can apply the product with a sponge. Make sure to soak the animal's fur with the diluted product. Unlike shampoos, you do not have to rinse the product. It is highly recommended that you put cotton balls in your pet’s ears during the application to protect them. It is also recommended that you not apply the product close to the animal's eyes.  Flea dips are usually only used in the worst of flea infestations. Talk to your vet to determine if this option is right for your dog.

How To Prevent Your Dog From Getting Bitten By Fleas

Anywhere the dog spends time sleeping or laying needs to be treated. Treat beds—either human or dog—carpets, furniture, under shady trees and bushes or porches.

Vacuuming:

For light infestations in your home, vacuuming every other day can eradicate 90% of the eggs. A vacuum with a rotating bar with a brush will destroy the eggs. Vacuuming will get rid of approximately 50% of the larvae and 60% of the pupa. After the first 3 weeks, you can dial back the vacuuming to 2 - 3 times a week. You can go back to normal vacuuming 5 months after the first initial treatment.

Vacuuming in conjunction with chemical carpet treatments will work. Vacuum the carpet first, then apply any of the chemical treatments that you are using. Vacuuming first will raise the carpet fibers. This allows the chemicals to reach deeper into the carpet. If you are using a spray, do not vacuum again until the carpet fibers are completely dry. Once dry, vacuum again to pull up any dead insects.

It is important to note that if you are using a canister vacuum that you make sure to empty your vacuum after each use.

Flea Collar In the Vacuum:

Some swear by the flea collar in the vacuum. If you want to try this be aware that this method only works for bagged vacuum cleaners. Get an inexpensive flea collar and place it in the vacuum cleaner bag. Vacuum the carpet, furniture anywhere the dog spends time. Any adult fleas that are sucked into the vacuum will die.

Sprays:

There are some products that you can spray in your home or yard to kill flea eggs and larva. This kind of spray should contain Pyriproxyfen. Concentrated sprays that contain IGRs generally last 7 months indoors. They will last approximately 3 weeks outdoors.

Foggers are not an effective way to treat a flea infestation. The chemical fog may not reach all the places where fleas could be hiding. If you choose to use a fogger, read the instructions before use.

Powders:

Flea powders for the carpet have also been effective for infestations. You sprinkle the flea powder on the carpet or furniture and let it sit for 24 - 48 hours and then vacuum thoroughly. You may need more than one application to kill all the eggs and adult fleas.

Professional Pest Control:

For extensive flea infestations, you may need to hire professional a pest control service to clear the home. Follow up with either flea sprays or powders that will kill flea eggs.

Final Thoughts
