Rivian stock surged 37% after it secured a $5 billion deal with Volkswagen.
The companies will form a joint-venture to develop next-gen vehicle software and electrical architecture.
Volkswagen’s investment secures Rivian’s capital needs ahead of its new R2 and R3 vehicle launches.

Rivian stock soared 37% on Wednesday after it struck a $5 billion deal with Volkswagen.

The two companies will form a joint-venture to collaborate on next-generation vehicle software and electrical architecture, which will be utilized in cars from both brands.

As part of the deal, Volkswagen will invest an initial $1 billion in Rivian via a convertible note that will convert into Rivian stock later this year, assuming the companies receive regulatory approval for the deal.

Volkswagen will then invest an additional $4 billion into Rivian, represented by two $1 billion common stock investments in 2025 and 2026, and a $2 billion investment into the joint venture by 2026 via both a $1 billion payment to the JV and a $1 billion loan to it.

The investment is seen as a pivotal lifeline for Rivian, which has yet to reach profitability since its founding in 2009.

“Not only is this partnership expected to bring our software and associated zonal architecture to an even broader market through Volkswagen Group’s global reach, but this partnership also is expected to help secure our capital needs for substantial growth,” Rivian founder and CEO RJ Scaringe said.

Rivian’s stock price has been trending lower since its November 2021 IPO. The stock is down 91% from its record high, and year-to-date is down 30% even after accounting for Wednesday’s share price gains.

But Wedbush analyst Dan Ives believes the gains for Rivian can continue.

In a note on Wednesday, Ives reiterated the firm’s “Outperform” rating and raised his Rivian price target to $20 a share, representing potential upside of 21% from current levels.

“This is a core game changer for Rivian and changes the capital structure of the company looking ahead for the story and the Street’s view at a key time,” Ives said.

The capital investment into Rivian comes ahead of its launch of a new suite of vehicles, the R2 and R3, which are successors to its original R1 vehicle platform.

“Importantly, this partnership will provide capital needed for the R2 ramp and GA plant R2/R3 midsize platform which we view as a large step in the right direction and a key move for Rivian going forward,” Ives said.

Rivian’s deal with Volkswagen comes just a few hours after the company said it simplified its manufacturing process to cut some costs by as much as 35%. The company said the cost savings should help it reach gross margin profitability by the end of the year.

Fleas and ticks are tiny parasites that cause big problems for dogs, from bites that make a dog’s skin itchy to the transmission of diseases like Lyme disease and tapeworms. The best flea and tick shampoos for dogs are one of the many options pet parents have to kill and repel these pesky parasites. The active ingredients in these products are chemical insecticides or natural essential oils.

We spoke with two veterinarians about how flea and tick shampoos work and what to look for in these formulas. We also researched dozens of shampoos and reviewed our top picks according to several factors, including their ingredients and how long they are effective. The best flea shampoo overall is Adams Plus Flea and Tick Shampoo with Precor, which kills fleas, ticks, and lice on contact and works for up to 28 days.

Shampoos can be a great first line of defense against fleas and ticks, especially when a dog has a heavy flea infestation. But make sure to use one of the best flea treatments for dogs year-round because shampoos don’t last as long as topical and oral floral treatments, according to Dr. Breanna Green, an associate veterinarian at Veterans Memorial Drive Animal Hospital. If you’re looking to treat a dog younger than 12 weeks old, check out our recommendations for the best flea and tick treatments for puppies.

Editor’s note: Flea and tick shampoos that contain pyrethrins and permethrin are toxic to cats and can be fatal. With exposure, cats can develop symptoms such as tremors, twitching, and vomiting. If you have a cat, choose a flea and tick shampoo free of pyrethrins and permethrin.

Best overall

“Flea and tick shampoo can help provide immediate relief for an uncomfortable pet,” says Green. Flea and tick bites are very itchy, making dogs scratch so much that their skin becomes red, raw, and irritated.

Our top pick for the best flea and tick shampoos for dogs, Adams Plus Flea and Tick Shampoo with Precor, kills all fleas at all life stages, ticks, and lice on contact and continues working for 28 days. It has a light coconut scent and contains skin-soothing ingredients like oatmeal. Green recommends oatmeal-based shampoos to relieve itching and skin inflammation from these bites.

This shampoo contains two insecticides: pyrethrins and S-methoprene. Pyrethrins kill adult fleas by disrupting their nervous system, while S-methoprene is an insect growth regulator (IGR) that prevents flea eggs from reaching adulthood. The shampoo also contains piperonyl butoxide to enhance the insecticides’ effectiveness. Precor is a brand of S-methoprene.

It should stay on the skin for five minutes before being rinsed out. Although the shampoo remains effective for 28 days, the manufacturer recommends bathing every seven to ten days for heavy flea infestations.

Best with essential oil

Richard’s Organics Flea and Tick Shampoo is insecticide-free and uses a combination of essential oils to kill fleas, ticks, and mosquitoes for up to 7 days. However, weekly bathing with even the best dog shampoos can dry out a dog’s skin, so this shampoo is only a short-term solution. This shampoo contains peppermint oil, a natural insecticide, and rosemary oil, which can reportedly repel parasites.

Essential oils in flea and tick shampoos for dogs are highly diluted. However, Green cautions that essential oils may irritate a pet’s skin.

The shampoo also contains sodium lauryl sulfate to help the essential oils mix with water during a bath and vitamin E to soothe the skin. It should remain on the skin for several minutes before being rinsed out.

Best budget

The best flea and tick shampoos for dogs do not have to be pricey to be effective. “High cost doesn’t always mean that a shampoo has better ingredients or is more effective at killing fleas and ticks,” says Dr. Tierra Price, a veterinarian at Veterinary Emergency Group.

Sentry Flea and Tick Shampoo with Oatmeal for Dogs and Puppies kills all life stages of fleas and adult ticks for up to ten days at an affordable price. Its active ingredients are permethrin, a synthetic version of pyrethrins, and piperonyl butoxide. The shampoo kills fleas soon after contact and takes one to two days to begin killing ticks.

Best fast-acting

If your dog has an active flea infestation, you want a flea and tick shampoo that works fast. “Fast-acting flea and tick shampoos may help kill existing fleas and ticks and resolve infestations quickly,” says Price. Zodiac Oatmeal Conditioning Flea and Tick Shampoo for Dogs and Puppies kills fleas, ticks, and lice on contact and works for up to 28 days. Bathing can be repeated every seven to ten days if a dog has an especially heavy load of adult fleas.

It also contains skin-soothing ingredients like lanolin and coconut extract, making it our top choice for fast-acting flea and tick shampoos for dogs.

The shampoo contains pyrethrins, piperonyl butoxide, and (S)-methoprene as its active ingredients. It should remain on the skin for three to five minutes before rinsing out.

Best long-lasting

Many flea shampoos for dogs work for up to ten days. Sergeant’s Guardian Pro Shampoo stands out because it kills adult fleas, flea eggs, and ticks for up to 30 days. It does not kill flea larvae, though, so it may not be as effective at breaking the flea life cycle as other flea and tick shampoos.

“Long-lasting flea and tick shampoos can repel fleas and ticks, but their effectiveness can be impacted by factors like swimming, bathing, and sunlight exposure,” says Price.

The shampoo has a fresh spring freesia scent and contains permethrin, pyriproxyfen, and piperonyl butoxide. Pyriproxyfen is an IGR that prevents flea eggs and larvae from reaching adulthood. The shampoo should stay on the skin for five minutes before being rinsed out.

Best unscented

“Pets can be allergic to flea bites, which can cause severe skin irritation and infection,” says Green. She adds that for dogs with sensitive skin, scented ingredients in flea and tick shampoos may further irritate the skin.

Advantage Treatment Shampoo for Dogs and Puppies is unscented and kills adult fleas and ticks on contact for up to seven days, making it our top pick for this category of flea and tick shampoos. This shampoo’s main active ingredient is pyrethrins. The other two active ingredients — piperonyl butoxide and N-Octyl bicycloheptene dicarboximide — help the pyrethrins work more effectively. The shampoo should remain on the skin for five minutes before being rinsed out.

Keep in mind that if a dog’s skin is severely irritated and infected, an over-the-counter shampoo may not be enough. “In these cases, I will prescribe a medicated antimicrobial shampoo,” says Green. You can find excellent options in our guide to the best medicated dog shampoos.

What to look for in a flea and tick shampoo for dogs

Our experts helped us narrow our criteria for choosing the best flea and tick shampoos for dogs. The advice below will help you choose the appropriate shampoo for your dog.

Number of parasites treated: While some flea and tick shampoos for dogs target just those two parasites, other flea and tick shampoos also kill lice and mosquitoes. Lice and mosquitoes can also make the skin feel extremely itchy. Mosquitoes can transmit diseases like heartworm, so flea and tick shampoos that treat lice and mosquitoes provide extra parasite control.

Flea life stage: The best flea and tick shampoo for dogs will kill all life stages of fleas, from eggs to adults. This will help treat an active infestation of adult fleas and break the flea life cycle.

Active ingredients: Flea and tick shampoos contain chemical insecticides or natural essential oils to kill fleas and ticks. The most common insecticides in flea and tick shampoos for dogs are pyrethrins, permethrin, and (S)-methoprene. Pyrethrins and permethrin target only adult fleas and damage their nervous system, while (S)-methoprene is an insect growth regulator that prevents flea eggs from becoming adults. Some shampoos also contain the active ingredient piperonyl butoxide to help the insecticides work more effectively.

Essential oils, such as cinnamon oil and peppermint oil, are the most common natural ingredients used in flea and tick shampoos. They don’t work nearly as well as chemical insecticides but may appeal to pet owners who don’t want to use chemicals on their pets.

Minimum age: Many flea and tick shampoos are safe only for dogs over 12 weeks old. If your puppy is younger than 12 weeks old, consider another treatment, such as oral flea treatment Capstar, which kills only adult fleas and is safe for puppies at least 4 weeks old. Your veterinarian can help you decide which flea and tick treatment will be the safest and most effective for your young puppy.

Instructions for use: Following the instructions on the shampoo bottle is crucial to a flea and tick shampoo working most effectively. Fortunately, flea and tick shampoos are easy to use. They should be worked into a rich lather, starting from the head and working toward the tail. Working from head to tail prevents fleas from jumping up your dog’s back during a bath. Also, the shampoo should stay on the skin for several minutes before being rinsed out to allow the shampoo’s active ingredients to work.

Duration of effectiveness: The best flea shampoos for dogs vary in how long they work to kill fleas and ticks. Many flea and tick shampoos are effective for 7 to 10 days, while others work for up to 28 or 30 days. Even for long-lasting flea and tick shampoos, the manufacturer may recommend more frequent bathing to maximize the shampoo’s effectiveness.

Scent: Flea and tick shampoos may contain artificial fragrances or essential oils for a pleasant scent. However, these ingredients may irritate the skin of dogs with sensitive skin. Also, shampoos with a strong scent may be off-putting to dogs and their owners.

Skin-soothing ingredients: Flea and tick bites are very irritating to the skin. Constant scratching and licking at the bite areas irritates the skin even more. When selecting a flea and tick shampoo for your dog, look for ingredients like aloe vera and oatmeal that soothe irritated skin.

Other pets in your home: Pyrethrins and permethrin are extremely toxic to cats. If a cat is exposed to these insecticides, they can develop symptoms like tremors, twitching, and vomiting. If you have a cat, select a flea and tick shampoo for your dog that is free of pyrethrins and permethrin.

How we chose the best flea and tick shampoos for dogs

We consulted two veterinarians about flea and tick shampoos. Their insights helped us select our top choices, but our experts did not endorse or recommend specific products.

Dr. Breanna Green is a small animal veterinarian and an associate veterinarian at Veterans Memorial Animal Hospital in Houston, Texas. She shared insights on flea and tick shampoos that contain essential oils and those that are ideal for sensitive skin and itch relief.

Dr. Tierra Price is an emergency veterinarian at Veterinary Emergency Group in Atlanta, Georgia. She provided her expert insight on budget flea and tick shampoos and flea and tick shampoos marketed as long-lasting and fast-acting.

We also consulted the Merck Veterinary Manual for general information about insecticides and reviewed guidelines on flea and tick control from the Companion Animal Parasite Council.

Dog flea and tick shampoo FAQs

What is the most effective flea and tick shampoo for dogs?

There is no single most effective shampoo. The best flea and tick shampoos for dogs typically contain insecticides like pyrethrin, which tend to work better than those with essential oils as their active ingredients. However, our experts agree that these shampoos are less effective than other flea and tick treatments, and pet guardians should not use them as the only form of flea and tick control.

Does flea and tick shampoo really work?

A flea and tick shampoo for dogs can be a good first line of defense against fleas and ticks, especially for active flea infestations. However, they do not work nearly as well or last as long as oral and topical flea and tick treatments. A common complaint with these shampoos is that fleas jump back on a dog soon after a bath. “The effects of flea and tick shampoos are short-lasting. If we do not also treat the environment and get a dog on adequate flea prevention, the adult fleas will jump back on the dog in a matter of days,” says Green.

Is there a dog shampoo that kills fleas?

There are many dog shampoos that kill fleas. To kill fleas, these shampoos contain insecticides, such as pyrethrins or highly-diluted essential oils. With so many dog shampoos available, it is best to talk with your veterinarian about which may work best for your dog. Also, you may need to bathe more than once if they have a heavy flea infestation.

What is the best thing to wash a dog to kill fleas?

Your best option is to use a shampoo formulated to kill fleas. You can choose a flea shampoo that contains insecticides or essential oils as active ingredients. Always follow product instructions to ensure you use the shampoo safely and effectively.
