7 Best All Natural Flea And Tick Prevention For Dogs | 200 Chews

This single chew pairs pest defense with joint support, so you buy one bottle instead of three.

The Puyrzoe 5-in-1 combines neem and brewer’s yeast for flea and tick resistance with glucosamine and chondroitin (compounds that support joint cartilage) for mobility. A 200-count supply covers your dog across fleas, joints, skin, immunity, and digestion in one beef-flavored soft chew. For active outdoor dogs or seniors, that means fewer bottles to manage.

Buyers report that three large dogs living next to a Tennessee woodline have been flea and tick free since starting this formula, with no wonky side effects. Unlike the Carmelie and YOTANGO chews which focus strictly on flea support, this one also supports hip and joint flexibility. A reviewer did mention dogs still scratching — the honest trade-off is that natural supplements reduce pest attraction but may not stop a heavy infestation right away.

A five-oil collar that kept a high-desert Lab tick-free through three Arizona summers, per one buyer.

This collar uses a blend of citronella, cinnamon, garlic, lemongrass, and thyme oils (all volatile essential oils that evaporate to form a repellent vapor) to create a scent barrier around the head and neck. It fits dogs 18 lbs and up with an adjustable 10–25 inch band. The 2-pack covers 8 months of protection. For owners who refuse chemical treatments after a bad reaction to Seresto (a popular synthetic collar), this is a common replacement. One reviewer noted her coonhounds had zero fleas or ticks near a county park, with no seizures like she saw with the synthetic collar.

Compared to the Allyeah 4-pack below, this collar has a stronger track record in tick-heavy regions like the Sonoran desert and Michigan. The honest catch: one buyer found a tick directly under the collar after two weeks, and another said it “worked for about 2 weeks.” The pack includes a grooming comb and tick removal tool for daily checks.

A short-ingredient-list chew made in the USA that some dogs love, but deliver pest defense is not guaranteed.

This chewable keeps its ingredient list lean — flax seed meal, coriander, neem, and a B-vitamin blend — and is manufactured in the USA. The 120-count container (chicken flavor) offers a simpler approach than the multi-function Puyrzoe. One owner reported their 8-year-old dog “loves these chews” and stays flea and tick free while running through grass.

The honest truth from reviews is split. A few owners said dogs got fleas anyway. One vet told a customer the ingredients “have no flea-repelling properties” and that the benefit is limited to coat improvement. This makes the Avid Paws a decent daily supplement for general health, but do not rely on it as your sole line of defense in a heavy flea area. It is more affordable than premium options, but that lower price reflects the simpler formulation.

Four collars for the price of one premium brand, but the protection may be lighter than the Fipukin collar.

This 4-pack uses a botanical blend of 3.20% cedarwood oil, 2.50% lemongrass oil, 2.10% rosemary oil, and 2.05% clove oil — each ingredient percentage is listed on the label. The collars adjust to fit any dog breed and are suitable for puppies 3 months and older. For a multi-dog household or seasonal rotation, the value of four collars at once is tough to top compared to the 2-pack from Fipukin.

One buyer in a heavy tick area called it the “best natural flea/tick repellent tried,” reporting only a few fleas and no ticks across three dogs all last year. However, another reviewer found 7 ticks on their dog after just 2 walks with a fresh collar. The manufacturer states this is a prevention-first approach — it supports a pest-free lifestyle but does not eliminate existing fleas or ticks directly. The smell is pleasant and natural, which multiple reviewers appreciated.

A 200-chew canister offers a low cost per chew, but effectiveness varies wildly from dog to dog.

This chicken-flavored soft chew packs 200 chews per can, which the maker says lasts over 3 months. The formula includes coconut oil, neem, flaxseed, brewer’s yeast, apple cider vinegar, and a full vitamin B complex. It is designed for all life stages and all breed sizes. The 0.42 kg weight is the same as the duck flavor version. Both come with a 2-year manufacturer warranty.

The reviews here are more polarized than any other product. One customer observed their Border Collie and Mastiff showed improved dry skin, reduced scratching, and healthier coats. But another owner of two Pit Bulls who had been flea-free for 5 years experienced an infestation right after starting this product. One user highlighted that only 1 out of 3 dogs stayed tick-free: a Chihuahua mix had none, but a Staffordshire mix had 7 ticks and an Aussie mix had 5, after 3 chews per day. The high count is a real draw, but the effectiveness varies dramatically by dog.

A brewer’s yeast-heavy formula that dogs love to eat, but a significant number of customers note it does not reduce fleas.

YOTANGO focuses on brewer’s yeast as the primary repellent active, supported by coconut oil, flaxseed, neem, fish oil, and apple cider vinegar. The company recommends starting with half a serving for 3–5 days, then increasing to a full serving. They note the supplement works gradually over 3–4 weeks. The 400-gram container holds 200 soft treats with a chicken flavor that multiple reviewers point out their dogs find easy to eat.

Here is the honest reality check: one reviewer has been using them “2x per day for the last few weeks” and reported “no change in the amount of fleas my dog attracts.” Another buyer simply called it a “big joke” and said the dog treats it like a regular treat. A more balanced review from an owner of three large dogs noted no ticks seen in 2 months and that fleas were “less prolific than before” — so there is some effect, just not total elimination. The product works well for a subset of dogs, but the failure rate in reviews is high enough to make this a cautious recommendation.

The same 200-count formula in duck flavor, for dogs that refuse chicken-based chews.

This is the duck-flavored twin of the Carmelie chicken chew. The ingredient list is nearly identical: coconut oil, flaxseed, brewer’s yeast, neem, fish oil, apple cider vinegar, and B vitamins. The main difference is the protein flavor, which the maker designed for picky eaters who reject chicken. It carries the same 2-year manufacturer warranty and 0.42 kg weight.

Reviews follow the same split pattern as the chicken version. One owner of two German Shepherds said “these really work” and that they prefer the natural approach to topical chemicals. But a more alarming report stated the product “gave my little dog seizures and neurological issues with big dog” — a serious claim, though it is a single report among verified buyers. Most positive reviews center on taste acceptance and some visible improvement in scratching, but the lack of consistent flea elimination across both Carmelie flavors is a pattern worth noting.
