How to Treat Fleas on Newborn Puppies That Are Too Young for Conventional Flea Treatments

Newborn puppies are ideal hosts for fleas to infest and lay eggs. Fleas (scientifically known as Ctenocephalides Canis) are pesky parasites because they can cause itching and irritation on a puppy's skin. In severe cases, puppies may suffer from anemia due to blood loss from flea bites. Unfortunately, removing fleas from puppies can be challenging since they are too small to tolerate strong flea treatments. Therefore, to treat fleas on a puppy, it's important to maintain good hygiene for the puppy, treat the mother dog for fleas, and clean any bedding or soft items the puppy comes into contact with. This guide provides more detailed information on how to manage flea infestations in puppies.

Understand why conventional flea treatments should not be used on newborn puppies. Newborn puppies provide an ideal environment for flea infestation due to their warm and moist skin, making it easy for fleas to feed on their blood. Unfortunately, no flea treatments are safe for newborn puppies. Their internal organs are more sensitive than adult dogs, making them more susceptible to the side effects of flea medications.

• Depending on the medication, potential side effects may include excessive drooling, vomiting, respiratory issues, and heightened sensitivity to stimuli or severe depression.
• Some flea products specifically state on the label that they are not suitable for puppies. Others have not been tested on puppies, so manufacturers often advise against using them for young dogs.
• It's especially important to avoid using flea products that contain Permethrin, as these are unsafe for newborn puppies. Puppies' weak metabolism struggles to break down Permethrin, causing it to accumulate in their bodies and potentially lead to nerve damage, resulting in severe shaking, drooling, paralysis, or even seizures.
• Flea products that do not contain Permethrin are often less effective and a waste of money.

Give your puppy a warm bath. Since there are no over-the-counter or prescription products suitable for puppies, the only option is to manually remove the fleas. To bathe a puppy, you will need to:

• Fill a basin or tub with warm water. The water temperature should be similar to that of a bath for an infant.
• Place the puppy in the water, holding its head above the water level.
• Use your hand to scoop water and pour it over the puppy's fur until it is thoroughly wet.
• Lift the puppy out of the tub and wrap it in a warm, clean towel. Gently dry the puppy off.

Use a comb to groom the puppy and remove fleas. Wrap the puppy in a dry towel and place it on a flat surface. Groom the puppy while its fur is still wet, removing all fleas.

• The teeth of a flea comb are usually very dense and can pull out fleas from the puppy's fur.
• Start combing from the neck and work through one section of fur at a time, ensuring that you cover the entire body to remove all fleas.

Kill the fleas by crushing or dropping them into boiling water. You should kill all the fleas after removing them from the puppy's fur to prevent them from returning and reinfesting. You can kill fleas by squeezing them between your fingers or dropping them into boiling water.

• Make sure to keep the cup of boiling water out of reach of the puppy to prevent it from getting burned.

Keep the puppy away from infected bedding or pets with fleas. After helping the puppy eliminate the fleas, you should keep it in a flea-free environment. However, do not spray flea prevention products on the puppy's fur. Instead, isolate the puppy from the mother or any untreated bedding that may still harbor fleas. This step helps prevent reinfestation of fleas in the puppy.

Know when it's safe to start using flea treatments on puppies. As the puppy grows, its body can handle flea treatment ingredients, making the medication safer. Always follow the instructions on the product label for the specific age when flea treatment can be used. Some licensed flea treatments for puppies include:

• Revolution (active ingredient Selamectin) can be used after the puppy is 7 weeks old.
• Frontline (active ingredient Fipronil) can be used after the puppy is 8 weeks old.
• Oral medications such as Comfortis (active ingredient Spinosad) are safe for puppies after 14 weeks of age.
• Do not use these products on puppies younger than the recommended age.

Understanding why treating fleas on mother dogs is crucial. If the puppies in a litter are infested with fleas, the mother is likely to be affected as well. Therefore, it is essential to treat the mother dog for fleas to prevent reinfection in the puppies.

• Remember that other animals in the household may also come into contact with the mother or puppies, so they could also be at risk of flea infestations and need treatment as well.

Only use prescription medications, avoid over-the-counter or "natural" remedies. While there are flea treatments available for mother dogs, you must choose carefully.

• If the mother is nursing, some chemicals in flea medications may pass into the puppies' bodies through the milk and cause harm. Therefore, only use prescription products specifically designed for nursing dogs.
• Some over-the-counter products are labeled as "natural" or "chemical-free," but that doesn't mean they are safe for the puppies. Even if they don't cause any noticeable side effects, these natural or herbal treatments are often much less effective in treating fleas.

Use Selamectin-based medications for pregnant or nursing mother dogs. Prescription drugs containing Selamectin (such as Revolution and Stronghold) are often approved for use in pregnant or nursing dogs.

• According to the manufacturer's instructions, the medication should be applied to the adult dog's skin and allowed to dry for several hours before the mother comes into contact with the puppies.
• Selamectin should only be used according to the recommended dosage and applied externally. Research shows that when ingested, Selamectin can cause abnormalities in fetal development in mice.

Avoid using medications containing Fipronil and Spinosad as they are unsafe for nursing dogs. Some flea treatment ingredients are not safe for pregnant or nursing dogs. Therefore, always check the label carefully or consult a veterinarian to avoid using medications with these ingredients.

• The ingredient Fipronil (found in Frontline flea treatments) should not be used on pregnant or nursing dogs, as its safety for puppies has not been established.
• The ingredient Spinosad (found in Comfortis oral medication) can pass into the mother's milk. It is uncertain whether Spinosad causes adverse reactions in puppies, so it is best to avoid using this product on nursing dogs.

Understand the flea lifecycle. Adult fleas typically search for a host to infest. For every flea found on a pet, it’s estimated that 20 more are living on bedding, carpets, and sofas.

• It's important to note that female fleas often lay eggs on soft surfaces like carpets and upholstery. Flea eggs are quite resilient, as they can remain dormant for years if they don’t find a suitable host.
• Once the eggs hatch, larvae and pupae develop on carpets or bedding, feeding on debris to complete their lifecycle and become adult fleas.
• Therefore, it’s crucial to remove eggs and larvae hidden in bedding, carpets, and sofas to prevent flea infestations for both adult and puppy dogs.

Wash the puppy bedding to eliminate fleas. As explained earlier, the environment where puppies live can harbor a lot of fleas, larvae, and pupae waiting to mature. Thus, bedding must be thoroughly cleaned and disinfected to eradicate fleas.

• Since flea eggs have an extremely tough outer shell, simply washing bedding in a washing machine may not be enough to kill them.
• Use a spray or bomb containing insecticidal ingredients. These chemicals can spread into every nook and cranny where flea eggs, larvae, and pupae are hiding. Be sure to follow the directions on the pesticide label.
• After applying the pesticide and allowing it to take effect, wash the bedding in hot water to remove any harmful chemical residues (which could harm the puppies) as well as any dead eggs, larvae, or adult fleas.

Spray insecticides to kill fleas on carpets and other fabric items. Finally, you need to eliminate all the fleas living on carpets or other soft materials. It's recommended to use insecticides containing Permethrin, such as Staykill or RIP Fleas.

• Manufacturers of insecticide sprays often suggest vacuuming before spraying. This loosens carpet fibers and helps the insecticide penetrate more deeply. Additionally, the vibrations from vacuuming may 'wake up' larvae that are hoping to find a host to infest.
• Spray the insecticide on carpets, sofas, and other fabric items as directed on the label. Permethrin in the spray works by paralyzing the nervous system, inhibiting muscle function, and ultimately killing the insects. Unlike mammals, insects cannot break down Pyrethroids, making them highly sensitive to the pesticide's effects.
• Ensure that puppies, other pets (including birds and fish), or children are kept out of the room during spraying. Once the spray has been applied, ventilate the room for several hours by opening windows to allow any remaining pesticide residue to dissipate.

If the mother dog, puppies, or other animals that may have been infested with fleas have been inside your vehicle, don't forget to spray insecticide inside the car.
