What Are Dog Fleas?

Fleas are tiny creatures that belong to the insect family. 

Fleas feed on the blood of mammals, for example, dogs and cats, although they can sometimes bite people, too. Amazingly, a flea can survive for a few months without feeding. However, female fleas must have a meal of mammalian blood before they are able to reproduce and lay eggs. 

A single flea can lay as many as 4,000 eggs on the host animal’s fur, so you can see just how quickly an infestation can take hold.

Flea eggs go through four lifecycle stages:

  • Embryo
  • Larva
  • Pupa
  • Imago (adult)

The flea’s lifecycle generally takes between two to three weeks, although that can take longer if conditions are cool.

Adult fleas are a reddish-brown color with long, flat bodies that measure only a millimeter or so in length. Fleas can’t fly, but they move around easily enough by vertically jumping up to eight inches! That enables a minuscule flea to leap onto a passing dog or cat (or person) for a meal.

What Do Fleas Eat?

As mentioned above, fleas feed on blood. A female flea can consume an incredible 15 times her body weight in blood every single day!

The fleas deposit partially digested blood on the skin of their host, which you might notice as “flea dirt.” The dirt is used as food by developing flea larvae but is also a clear sign of fleas, making it easy for you to spot a flea infestation.

Can Fleas Cause Diseases?

Yes! Not only can fleas make your Doodle’s life a misery by constantly biting him, but they can also present a serious health threat.

General Discomfort

Flea bites and their activity on the dog’s skin make your pet itch. As a result, your dog will constantly scratch himself, damaging the hair follicles.

Some pets even chew and bite themselves in an attempt to remove the irritation that the fleas cause, tending the skin towards infection.


Goldendoodles can have sensitive or dry skin, and some suffer from allergies and dermatitis that causes long-term damage to the dog’s hair follicles, leading to bald patches. FAD (Flea Allergy Dermatitis) is a very common skin condition that the chemicals in flea saliva can cause.

If a very severe, continuous flea infestation occurs, your dog could develop anemia. That’s especially common in puppies that have come from puppy mills, where no parasite prevention program is in place.


Fleas can carry tapeworm eggs, passing them onto the animal they bite in residual blood. Tapeworm can be a serious problem for dogs that are not dewormed regularly.

What Happens When A Flea Bites A Human?

Although fleas don’t live on humans (not enough fur!), you can still be bitten by fleas if your home is infested. That can put you at risk of some nasty health problems, including:


Just like your Goldendoodle, you can suffer an allergic reaction if you’re bitten by fleas. Generally, you’ll notice tiny red or purple raised lumps called papules on your skin. Often, the bites are very itchy and uncomfortable, and there’s the risk of infection if you scratch them.


Tapeworm (Dipylidium caninum) can be spread through flea bites but is more commonly suffered by children if they swallow a flea and ingest it.


Typhus is a group of diseases that can cause a range of symptoms, including headaches, fever, rashes, and confusion. There are two strains of typhus that you can contract from flea bites:

  • Murine typhus: A form of bacterial typhus that can be spread by rodents but also by the common flea types that are found on dogs and cats.
  • Flea typhus: This form of typhus is caused by Rickettsia felis and is only spread by the fleas that are found on cats.

Bubonic Plague

Although bubonic plague (Yersinia pestis) is usually associated with diseases of the Middle Ages, rodent fleas can sometimes make the leap onto dogs and cats in some regions. Potentially, these types of fleas can be vectors of the plague if they bite humans.

How Do Fleas Spread?

Fleas spread in several ways:

Pet-To-Pet Transfer

The most common method of infestation is between animals. 

So, if your Goldendoodle mixes with other dogs at the dog park that are carrying fleas, the chances are that the parasites will simply jump onto your dog. It then follows that every other dog and cat your dog socializes with will also pick up a flea or two. Before you know it, an infestation has broken out!


Wildlife, including foxes, deer, possums, and raccoons, can pass fleas onto your dog. 

So, if you live in a rural area where your Doodle enjoys going hunting with you, there’s a good chance he might pick up some fleas through interaction with wildlife.

Pet Bedding

If your dog has fleas, it’s pretty much a certainty that they will find their way into his bedding (and potentially into your bed and furniture too!) Also, if your dog has a soft dog crate, there’s a good chance that fleas will be deposited in the soft lining.

How Can You Prevent Your Goldendoodle From Getting Fleas?

Happy Goldendoodle

Once fleas get into your home, they can be extremely difficult to eradicate. So, you need to know how to prevent that from happening.

Discourage Wildlife

Discouraging raccoons and other wildlife from invading your garden and garage where they could potentially pass on fleas to your Goldendoodle can lead to a reduction in fleas on your property.

So, avoid leaving out food and rubbish that might attract pests.

Protect Your Home!

If you have friends who bring their pets to your home, politely ask that they have their animals treated with a flea prevention product before they visit. That will stop fleas from getting into your home in the first place.

Remember that fleas can break into your home on rodents, so if you have an issue with mice or rats around your home or garden, take action to get rid of them.

Be Disruptive!

If you discover fleas in your home, take action to disrupt the fleas’ lifecycle.

  • Wash all your pets’ bedding in hot water to kill flea eggs and adults.
  • Vacuum all your carpets and floor coverings thoroughly to remove flea eggs that might have fallen there. Empty the vacuum cleaner outside your home and burn the contents.
  • In cases of severe infestation, have your carpets steam-cleaned.
  • Put soft dog toys or kids’ plushy toys in a sealed bag in your freezer for 24 hours. Fleas thrive on heat and humidity, and a day in the deep freeze will almost certainly kill them off. 

If your home is very severely infested with fleas, we recommend that you ask a good pest control company for advice. It could be necessary to have your home professionally treated to see a substantial reduction in fleas.

Flea Prevention Treatment

The most effective way to prevent your Doodle from picking up fleas from other animals or infested bedding is to treat your pet regularly with a flea prevention treatment product. You’ll need to treat all the pets in your household at the same time to ensure that the preventative treatment remains effective.

Treats dogs up to 125 pounds

Palatable tablet form

Novartis Capstar is a best-selling effective flea treatment product that’s recommended by vets. This is a Nitenpyram-based drug that you administer via a tablet. Although the tablets are palatable, the easiest way to persuade your pet to eat the pill is to hide the tablet in food.

Capstar maintains that their product is effective at eliminating up to 90% of adult fleas on dogs, working in as little as 30 minutes.

Nitenpyram is extremely safe for your dog and causes very few side effects. You can use the tablets to provide relief from fleas for nursing mothers, pregnant Goldendoodles, and puppies as young as four weeks old, alongside regular flea prevention treatments.

2. K9 Advantix II Flea and Tick Prevention

K9 Advantix II Flea and Tick Prevention for Large Dogs

Convenient topical treatment

For Medium to large-sized dogs

Highly effective and safe

Bayer makes a broad range of veterinary medicines, including this spot-on prevention treatment for dogs. Note that you can’t use this treatment on your cat.

Bayer K9 Advantix II comes in a handy 2-pack, which is ideal if you have two dogs. This veterinarian-recommended flea treatment has an added bonus in that the treatment also repels and kills mosquitoes, which is important for you if you live in an area where these biting insects are a problem. That’s a real plus point of this product, as very few others offer that.

Unlike many other products that need the tick or flea to actually bite your Goldendoodle before the drug becomes effective, K9 Advantix II is a topical formula, meaning that it works on contact. That’s great, as it means that your dog won’t need to endure irritating flea bites before the pests die. 

The drug works for up to 30 days, killing ticks and fleas within 12 hours, and providing long-lasting defense against parasites. After 24 hours, the treatment is waterproof, so your dog can go swimming or have a bath without losing the protection given by the drug.

  • Effective flea, tick, and mosquito control for dogs, cats, and other pets
  • The drug remains effective after 24 hours if your dog gets wet

You can use the treatment on adult dogs and on puppies from ten weeks of age. Start treatment immediately you discover fleas on your dog. The chews are suitable for dogs that have food allergies to beef or chicken, as the ingredients don’t include any animal proteins.
