What Happens When Fleas Get On Your Dog

Find out what happens when fleas get on your dog, and learn to pick up on the signs that fleas have plagued your pet.

Is your dog jumpy? Has your dog been grooming even more than usual? These could be tip-offs that your pet has caught fleas. In addition to causing your pet discomfort, fleas can lead to diseases, and a dog with fleas can spread pests around your home. Find out what it is like for your pet to host fleas, and learn to recognize the signs that fleas are tormenting your dog.

Flea Bites Are More Than Just Itchy

Flea bites, like mosquito bites, are more than just itchy. Fleas, like mosquitoes, bite for sustenance -- your pet's blood is a flea's dinner. Along with their saliva, fleas inject an anticoagulant chemical when biting. This anticoagulant is an irritant, causing redness and itching. For some pets and people, the bites won't be a big deal, but for many pets, the bites are more than just a nuisance.

Fleas bite frequently, and new generations of fleas are born and develop quickly into adults. Given the volume of bites, pets can potentially grow anemic from the depletion of blood. If your dog is extremely lethargic and has pale gums, this is a tip-off that your pet may have fleas. Fleas can also carry diseases and transmit them through bites, making them carriers of problems like tapeworm infestation.

Flea bites can start to resemble hives and welts. Grooming may become somewhat obsessive and incessant as your pet tries to solve the flea problem. Rather than eliminating the problem, excessive grooming can lead to hot spots and hairless patches of fur on your dog. In particular, you may see your pet lick, bite, and gnaw a lot around their paws. Dog scratches from flea bites can lead to skin infections and other skin diseases if left untreated.

Behavior Changes Caused by Flea Infestation

Fleas can also cause your pet to behave differently -- your dog might seem very skittish and jumpy in response to bites and discomfort. Flea allergy dermatitis is a common condition in pets allergic to flea saliva, leading to intense itching and irritated skin. You might notice your pet avoiding certain previously comfortable spots in the house, which might be associated with fleas and mites. Live fleas can make your pet uncomfortable and restless.

Adult Fleas Make Pets Their Home

Unlike mosquitoes, fleas will persistently stick around, making a pet a host animal and feeding upon them for days or weeks if no treatment is used. Adult fleas will lay eggs on your pet, and they generally roll onto the surrounding area. (If your dog likes a carpeted corner or has bedding, those are likely locations for flea eggs.) Once fleas progress through the life cycle to the adult phase, eating is imperative, and the new adult flea will use your pet as a feeding ground. Once fed, fleas will lay eggs, perpetuating the cycle.

In addition to using your pet as a source of sustenance and a place to lay eggs, fleas also excrete on your pets. You may see flea dirt -- the dark reddish-brown feces of fleas -- on your pet's skin. You may also see this flea dirt on carpets or bedding. Flea droppings, or flea dirt, are a clear sign of infestation.

Understanding Flea Life Cycle and Control

The flea life cycle consists of four stages: egg, larva, pupa, and adult. To get rid of fleas effectively, it is essential to target all stages. Flea products, such as flea shampoos and spot-on treatments, are designed to kill fleas at various life stages. Female fleas can lay up to 50 eggs a day, making it crucial to use treatments that kill adult fleas and prevent eggs from hatching.

Fleas live in various environments, but they thrive in warm, humid areas. Adult fleas feed on your pet's blood meal, which is necessary for their reproduction. Preventing fleas from feeding and laying eggs is key to breaking the flea life cycle. An adult female flea can lay numerous eggs, perpetuating the infestation cycle.

Spotting Fleas and Addressing Infestations

To spot fleas, check your pet's fur, especially around the neck, tail, and belly areas. Flea combs can help identify fleas, flea dirt, and flea eggs. If you find fleas, take immediate action to get rid of them. Medicated shampoos and flea treatments can help kill adult fleas and prevent new infestations. A few drops of flea medication on your pet's skin can effectively kill fleas and provide relief.

Preventing Fleas in Your Home

Keeping your home flea-free involves regular cleaning and vacuuming, especially on carpets, rugs, and upholstered furniture. Washing your pet's bedding in hot water can kill fleas and their eggs. Using tick prevention and flea control products year-round is essential to prevent infestations.

Flea Treatments and Medications

We recommend preventing a flea problem before it starts with the use of simple, effective, spot-on or oral treatments like K9 Advantis II or Comfortis. These treatments help kill fleas, including adult fleas, flea larvae, and flea eggs, effectively disrupting the flea life cycle. Treatments like Frontline Plus or Advantage II can also be very effective. Flea shampoos are also available and can be used to bathe your pet to get rid of fleas on contact.

Natural Flea Treatments and Herbal Remedies

Natural flea treatments are available for those looking to avoid chemicals. Herbal treatments, such as those containing essential oils, can help repel fleas and prevent infestations. Maintaining a clean home environment and using a flea comb regularly can also help control infestations.

Tick Remedies and Preventative Measures

Ticks can also pose a threat to your pets. Regularly checking your pet for ticks and using tick prevention treatments can help keep your pet safe. Tick remedies, such as tick collars and spot-on treatments, can be effective in preventing tick infestations.

Dealing with Severe Flea Infestations

In cases of severe infestations, professional pest control services may be necessary. These services can effectively eradicate fleas from your home. Combining professional treatments with regular use of flea products can help maintain a flea-free environment.

What if My Dog Eats a Flea or Tick?

The short answer is don't worry too much if your dog eats a flea or a tick. Your pet's stomach is strong enough to handle accidental insect ingestion, and so are you! Watching your dog pick up a dead bug with the tip of his tongue might not be the most pleasant sight, but as long as it's not a regular occurrence, there is no cause for concern.

However, if your pet has developed an affinity for munching on bugs, I wouldn't be as cavalier about their crunchy diet. Speak with your veterinarian or a pet specialist if you notice flea and tick ingestion becoming a common problem. When fleas are consumed regularly, the probability of your dog developing tapeworm greatly increases. One flea is enough to cause an issue if it carries tapeworm eggs.

Fleas often feed on pet feces, and they are known to carry tapeworm eggs in their system, which can be transmitted to dogs upon digestion. In most cases, a dog's stomach acid should be strong enough to kill off the egg before it hatches. The same goes for ticks. If a tapeworm does happen to develop, there are several safe and efficient treatments.

To prevent tapeworms, be diligent about preventative flea and tick control year-round. If your cat or dog is on a regularly scheduled treatment plan, the possibility of dead fleas, eggs, or larvae being accidentally eaten greatly decreases. On the same token, stay diligent about your pet’s hygiene as well as the cleanliness of your home to ensure a happy and healthy life for your pet.

Flea Allergies and Skin Reactions

Flea allergies can cause severe reactions in pets, leading to allergic reactions and skin irritations. If your pet shows signs of intense itching, hair loss, or irritated skin, consult your veterinarian for appropriate treatment. Regular use of flea control products and maintaining good hygiene can help prevent flea allergies.

Maintaining Your Pet's Coat and Health

Regular grooming and bathing with medicated shampoos can help maintain your pet's coat and prevent flea infestations. A healthy dog's coat is less likely to harbor fleas, and regular use of flea control products can keep your pet comfortable and flea-free.

Following these guidelines and using appropriate flea treatments can ensure your pet's health and comfort while keeping your home free from fleas.

Frequently Asked Questions

How harmful are fleas to dogs?

This disease can cause a range of symptoms, including fever, lethargy, and swollen lymph nodes. In addition to causing physical harm, fleas can also be a nuisance for both you and your dog. Fleas can infest your home and yard, and they can be difficult to eliminate once they become established. It's important to take steps to prevent fleas from infesting your dog and your home. This can include using flea-preventative products, regularly grooming your dog, and keeping your yard and home clean. If your dog does develop a flea infestation, it's important to take steps to eliminate the fleas as soon as possible to prevent further harm to your dog.

How can you tell if a dog has fleas?

There are several signs that may indicate that your dog has fleas. If your dog is constantly scratching or biting at their skin, it could be a sign that they have fleas. You may be able to see small, dark fleas crawling on your dog's skin or in its fur. Flea dirt is the excrement of adult fleas, and it looks like small, dark specks. If you see these specks on your dog's skin or in their fur, it could be a sign that they have fleas. If your dog has fleas, their skin may become red and inflamed, especially around the areas where they are biting or scratching. Fleas can also cause hair loss in dogs due to excessive scratching and biting at the skin.

This can include using flea-preventative products, regularly grooming your dog, and keeping your yard and home clean.

What kills fleas on dogs instantly?

There are several products that can kill fleas on dogs quickly and effectively. Topical flea preventatives are applied to the skin on the back of the neck and contain ingredients that kill fleas and prevent new infestations. Some popular topical flea preventatives include Frontline Plus, Advantage, and Vectra 3D. Oral flea preventatives are given to your dog orally and contain ingredients that kill fleas and prevent new infestations. Some popular oral flea preventatives include Capstar and Comfortis. There are shampoos that contain ingredients that kill fleas and can be used to treat a flea infestation.

Flea combs are fine-toothed combs specifically designed to remove fleas and flea eggs from your dog's fur. Be sure to comb your dog's entire body and dispose of the fleas and flea eggs immediately. It's important to note that these products should be used according to the instructions on the label and only as directed by your veterinarian. It's also important to note that some of these products may not be suitable for all dogs, so be sure to consult with your veterinarian before using any flea treatment products on your dog.

How long does it take to kill fleas on a dog?

The length of time it takes to kill fleas on a dog will depend on the specific product you are using and the severity of the flea infestation. Some products may be more effective at killing fleas than others, and some may work more quickly than others. Topical flea preventatives and oral flea preventatives are generally effective at killing fleas within 24 hours of application. Shampoo products may be effective at killing fleas within a few hours of use, but they may need to be reapplied multiple times to eliminate the infestation fully. It's important to follow the instructions on the product label and use the product as directed. If the flea infestation is severe, it may take longer to eliminate the fleas fully. In these cases, it may be necessary to use multiple products in combination or to seek the help of a veterinarian. It's also important to remember that flea treatment products are not a one-time solution. To prevent future flea infestations, it's important to use flea prevention products on a regular basis and to maintain good hygiene practices in your home and yard.

Can I sleep with my dog if it has fleas?

It is generally not recommended to sleep with your dog if it has fleas. Fleas can bite humans as well as pets, and they can transmit diseases to humans. Fleas can also cause allergic reactions in some people, leading to symptoms such as itching and rashes. If your dog has fleas, it's important to take steps to eliminate the fleas as soon as possible to prevent further harm to your dog and to prevent the fleas from spreading to other areas of your home. This can include using flea-preventative products, regularly grooming your dog, and keeping your yard and home clean. If you are concerned about fleas, it may be best to avoid sleeping with your dog until the flea infestation has been completely eliminated. If you do need to sleep with your dog while it has fleas, be sure to use a flea prevention product on your dog and to use protective measures, such as wearing long sleeves and pants, to prevent flea bites.
