Have you noticed your dog scratching more than usual? Or frantically biting themselves, especially on the base of their tail? Perhaps you can see evidence of hair loss, or red bumps on the skin on their lower legs.
While this could be the result of an environmental or health condition, it's most likely that your dog has fleas - parasites that live in your pooch's fur and feed on their blood. 🩸
Blood-sucking parasites are always an unwelcome addition to the family, but armed with some knowledge and a targeted treatment plan, you can help your dog find relief from these pests in no time at all.
Keep reading to learn how to identify fleas, get rid of them quickly and prevent their return.
What are fleas?
Fleas are tiny parasites that live on their host, feed on their blood and make life miserable for dogs (and their owners).
The type of flea most likely bothering your dog is Ctenocephalides felis, which is better known as the "cat flea" 😿, although it doesn't limit itself to cats 😼. This pesky insect is happy to latch onto dogs, and even humans in some cases, making it a common nuisance in many households.
Fleas thrive in warm, humid spots, which means they can be active all year round, especially indoors where it's nice and cosy.
These parasites are tiny - usually between 1 and 3 millimetres long - and reddish-brown, making them hard to see unless you're looking closely. But don't let their small size fool you. Fleas are built to be resilient; their flat bodies allow them to weave through fur, and they've got powerful back legs that help them jump up to 200 times their body length. This impressive leaping ability means they can hop easily from one animal to another, quickly spreading and making themselves at home.
Fleas aren't just a mild annoyance as they can cause real discomfort and health issues. Their bites are incredibly itchy, causing dogs to scratch and bite at themselves, which can lead to red, irritated skin and even infections. Some dogs are allergic to flea saliva, which only makes the reaction worse. In severe cases, especially in puppies or smaller dogs, flea infestations can lead to anaemia due to blood loss. And as if that's not enough, fleas can carry other parasites, like tapeworms, that can infect dogs.
Flea life cycle
The flea life cycle is a major reason why these little pests are so hard to get rid of, especially when they settle on your dog.
Understanding how fleas develop from start to finish is key to breaking the cycle and keeping your dog - and your home - flea-free.
The flea life cycle has four stages: egg, larva, pupa, and adult, and each one plays a role in keeping the infestation going.
- Eggs 🥚
It all starts with adult fleas feeding on your dog's blood, which they need to reproduce. Once they've had a meal, female fleas can lay up to 50 eggs a day. These eggs don't stick around on your dog; they fall off in the surrounding environment - onto carpets, bedding, and anywhere your dog likes to hang out. This means your dog's favourite spots become potential flea breeding grounds pretty quickly. - Larvae 🐛
A few days later, the eggs hatch into tiny, worm-like larvae that wiggle their way into dark, hidden spots like deep in carpets, cracks in the floor, or under furniture. They're not after blood just yet; instead, they feed on organic matter and “flea dirt,” which is basically dried flea droppings left behind by the adults. Flea larvae can stay like this for a few weeks, growing quietly and waiting for the next stage. - Pupae
Next comes the pupa stage, where the larvae wrap themselves up in sticky little cocoons. This stage is the most resilient and toughest to deal with. The cocoons are hard to spot and even harder to kill, especially since they can stick to fabrics and bedding. Inside the cocoon, the fleas develop and can stay hidden for months, waiting until they sense a host nearby (like your dog) before they hatch. Warmth, vibrations, and even carbon dioxide from a passing pet or person can trigger them to emerge as adult fleas. - Adults
Once they're out, the adult fleas are ready to jump onto your dog, feed, and start laying eggs all over again. And just like that, the cycle keeps on going.
Breaking the flea cycle means targeting every stage - something we'll cover in detail later.
Signs your dog has fleas
If you've noticed your dog scratching more than usual, it could be a sign that fleas have moved in.
Fleas aren't just an itchy nuisance; they can make your dog pretty uncomfortable and even lead to health issues if left untreated.
Here are some key signs to watch for that might mean your dog is dealing with a flea problem.
Scratching and biting
The first and most obvious sign is scratching and biting, as fleas bite and feed on your dog's blood, which causes itching.
If you notice your dog scratching a lot - around the base of the tail, behind the ears, or on the belly - that could be a telltale flea signal. Especially so if they scratch themselves frantically or with a degree of urgency that seems unusual.
Some dogs even nip or bite at their skin in an effort to get rid of the itch, so if you catch your dog frantically gnawing at certain spots, it's worth investigating.
Red bumps and inflamed skin
Another sign is red bumps or irritated skin.
Flea bites are irritating on their own, but some dogs are actually allergic to flea saliva, which can make the reaction even worse.
If you see little red dots on your dog's skin, or if the skin looks inflamed or raw, fleas could be the culprit. Dogs with flea allergies might develop larger patches of irritated skin or even lose some fur from all the scratching and biting. The base of your pooch's tail is one area in particular to keep an eye on.
Flea dirt 💩
A close inspection can sometimes reveal “flea dirt,” which is basically flea poop.
Flea dirt looks like tiny black or brown specks, usually found around the base of the tail, neck, and belly.
If you're not sure whether it's dirt or flea droppings, try placing a few specks on a damp paper towel. Flea dirt will turn reddish-brown when wet since it contains dried blood.
If you often let your dog sleep on the sofa or your own bed, flea dirt may find its way onto the upholstery or bed sheets. Sleeping in a bed amidst flea poop is something I'm sure we'd all rather avoid.
You might even catch a glimpse of the fleas themselves. Fleas are small, dark, and move fast, so spotting them isn't easy. Check areas where your dog's fur is thinner, like the belly or inner thighs, as fleas like to hang out there. You can also try running a fine-tooth flea comb through your dog's fur to see if you catch any fleas or flea dirt.
Finally, keep an eye on your home. If you're seeing small, itchy bites on yourself or other pets, or if you notice tiny, jumping insects in your dog's bedding, fleas might be spreading around the place.
Early detection can save you a lot of trouble, so if you spot any of these signs, it's time to take action to get those fleas out of yours and your dog's life!
How to check for fleas
If you suspect fleas, a quick, thorough inspection can confirm it and help you act quickly.
Here's how to check your dog for fleas in a few simple steps:
- Prepare your space and gather supplies
Set up in a well-lit area where you can see clearly and ideally somewhere you don't mind cleaning up afterwards, like a bathroom or outside space. Have a fine-tooth flea comb, some paper towels, and a bowl of soapy water at the ready. - Examine high-risk areas
Fleas love warm, cosy spots with easy access to blood vessels. Start by parting the fur and closely examining the skin around the base of your dog's tail, behind the ears, under the belly, and along the inner thighs. These spots are prime flea territory, so inspect them carefully. - Run a flea comb through the fur 🪮
Gently comb through your dog's fur, focusing on the areas mentioned above. After each pass, check the comb for fleas or dark specks. Fleas themselves are tiny, dark, and fast movers, but the comb will help you catch them. Dip the comb in the soapy water if you do find any live fleas, as this will prevent them from escaping. - Check for flea dirt 💩
If you spot dark specks, place a few on a damp paper towel to confirm that it's flea dirt. As we mentioned earlier, true flea dirt, or flea droppings, will turn reddish-brown when wet because it contains blood. This can confirm an infestation even if you haven't seen any live fleas.
- Inspect your dog's skin for reactions
As you comb, keep an eye out for red, irritated patches on your dog's skin. Some dogs react to flea bites with inflamed skin or red bumps, so any unusual skin irritation could be a sign that fleas have been at work. - Regularly check bedding and common areas 🛏️
For peace of mind, do a quick check of your dog's bedding, carpets, and common resting spots in your home. Any evidence of fleas or flea dirt here can indicate a larger issue and prompt further action.
By following these steps, you can thoroughly inspect your dog for fleas without the risk of missing anything.
This process not only helps confirm the presence of fleas but also ensures you catch an infestation early before it spreads.
Flea treatment
Dealing with fleas can feel like an uphill battle, but with a targeted treatment plan it's a battle you can win - and win fast.
Flea treatments come in various forms, from quick-acting topical solutions to longer-term prevention methods.
Here's a straightforward guide to getting rid of fleas on your dog and keeping them from coming back.
Spot-on treatments
Spot-on treatments are one of the most popular ways to treat fleas, and they're both effective and easy to apply.
These treatments come in small tubes and are applied directly to your dog's skin, usually between the shoulder blades, where they can't lick it off. They work by killing adult fleas on contact and usually last for around a month.
Spot-on treatments target the fleas on your dog while also preventing new ones from setting up camp. They're available from vets and pet shops, and they start working fast, making them a great first step if you're dealing with an active flea problem.
Flea tablets 💊
Flea tablets, or oral treatments, work from the inside out. When your dog ingests the tablet, the active ingredients get into their bloodstream, meaning fleas die when they bite your dog's skin.
Some tablets start working within hours and can kill adult fleas very quickly, so they're especially handy for severe infestations when you need fast relief.
However, they often won't offer long-lasting protection unless used regularly, so they may be best combined with other preventative measures. It's also worth bearing in mind that some dogs may be sensitive to the ingredients in oral treatments, so it's important to monitor your dog during treatment to ensure their wellbeing. This applies especially to pregnant dogs.
Flea collars
Flea collars have come a long way and can now offer effective, longer-lasting flea prevention, typically for up to eight months.
These collars release small amounts of active ingredients over time, which spread through your dog's coat and repel or kill fleas on contact. They're a great option if you want an easy solution that requires minimal upkeep. Just pop the collar on and let it do its job.
However, make sure your dog is comfortable wearing a collar for extended periods, especially if they're not used to it.
Flea shampoos and sprays 🫧
Flea shampoos and sprays can offer immediate relief and are ideal for when you're first treating a flea problem.
A good flea shampoo kills adult fleas on your dog during the bath, and sprays can be applied directly onto the fur afterward to keep fleas at bay. While shampoos and sprays don't usually have long-term effects, they're a good initial treatment to knock out a large portion of fleas quickly.
Use these with care, as some dogs have sensitive skin that can react to harsh chemicals.
Home and environment treatments
Treating your dog is only half the battle; you'll also need to tackle your home to make sure fleas don't come back.
Flea eggs and larvae can live in carpets, upholstery, and bedding, so a thorough clean-up is essential. ✨
Start by washing your dog's bedding and any fabric your pet frequently uses in hot water. A 40°C wash should do it, and drying on high heat will also help.
Vacuum your carpets, rugs, and furniture regularly, especially where your dog spends time.
There are also flea sprays specifically for household use, which can help kill eggs and larvae in those hard-to-reach spots. Some people also choose to sprinkle diatomaceous earth (a natural powder) onto carpets and let it sit for a few hours before vacuuming, as it can kill fleas without the use of chemicals.
Consistency is key
When it comes to flea treatment, consistency is crucial.
Fleas have a persistent life cycle, so even if you kill the adult fleas, there may still be eggs and larvae around waiting to hatch.
Following up with regular treatments and keeping an eye on your dog will help make sure the fleas are well and truly gone. Even after the immediate infestation is under control, using preventative treatments every month or as recommended can help keep your dog protected in the long run.
With a bit of patience and a consistent approach, you can tackle fleas and prevent them from becoming a recurring problem. From spot-on treatments and tablets to flea shampoos and home sprays, there's a solution for every pet and lifestyle, so you can say goodbye to these pesky parasites for good.
How do dogs get fleas?
You may be wondering how your dog ended up with fleas in the first place.
Fleas are experts at hitching a ride, and there are quite a few ways these pests can find their way onto your dog.
Here are the most common ways dogs pick up fleas:
Other animals 🦊
One of the easiest ways for your dog to get fleas is from other animals. Fleas don't discriminate - they're happy to hop from one animal to another. If your dog has been around other pets, like cats or other dogs, they could easily have picked up a few hitchhikers.
Outdoor adventures
Fleas love to hang out in tall grass, piles of leaves 🍂, and shady spots. When your dog is out exploring or sniffing around in the garden, there's a good chance they could pick up fleas waiting in the grass or bushes. Even well-maintained parks can have fleas lurking around in vegetation, ready to jump onto a passing host.
Pet boarding and grooming facilities
Any place with lots of pets can be a potential flea hotspot. Boarding kennels, doggie daycares, grooming salons, or pet-friendly cafes can be common sources, especially if other pets there have active flea infestations. Even with good cleaning practices, it only takes one dog with fleas to create a problem.
Your own home 🏡
Fleas can sneak into your home in all kinds of ways. If you have other pets or live in a shared building with pets, fleas can come in through shared spaces or even by hitching a ride on your clothes. Once they're inside, they're quick to find your dog and settle in.
Human visitors 🧑🦲
Sometimes fleas hitch a ride on people too! If you or a visitor has been around animals with fleas, it's possible for fleas to travel into your home on clothing or bags and find their way onto your dog. Fleas are small and sneaky, so they're easy to overlook.
Fleas are opportunistic pests, always looking for a new host. Knowing how they get around helps you understand where your dog might be picking them up and can give you an edge in preventing future flea troubles.
And sadly, yes, fleas can bite humans - although they tend not to live or reproduce on a human host, as their preferred habitat is animal fur.
Preventing fleas in dogs
Preventing fleas in dogs is all about adopting a few simple habits.
Regular treatments, like spot-ons, flea collars, or tablets, create a protective barrier that keeps fleas off your dog. Many of these treatments only need applying once a month or every few months, making it straight-forward to stay on top of the problem.
Keeping your home clean is also important, as flea eggs and larvae can settle into carpets, bedding, and furniture. Frequent vacuuming and washing of your dog's bedding, along with the occasional use of a pet-safe flea spray in high-traffic areas, can help prevent fleas from establishing a foothold.
After walks or park visits, a quick brush or flea check can catch any stragglers before they cause trouble.
Regular grooming and bathing keep your dog's coat less inviting to fleas, and reducing contact with wildlife like foxes or squirrels - common flea carriers - lowers the risk of picking up fleas outdoors.
With these simple steps, you can keep your dog flea-free and comfortable! 🐕
