best flea collars for small dogsIt is important that your pup has suitable flea and tick treatment to reduce the chance of catching the nasty diseases caused by these parasites. We understand that it can be difficult to choose a product as there are so many on the market now, but, having all done the struggle of pinning your pet down once a month to administer topical treatments or baths, we feel that flea collars are the most practical method.

Our top choice for the best flea collar for small dogs

The Seresto collar is a great choice as it comes in a size specifically made for smaller dogs and puppies and gives you the flexibility to shorten the collar further if necessary. It is also long-lasting (up to 8 months) and can be worn with a regular collar. Overall, it appears to be one of the best-value collars on the market as it is safe to wear all the time.


Why are flea collars important?

Fleas and ticks not only cause your dog (and you!) a lot of discomfort, they can also spread some nasty diseases. To avoid itching, illness and huge vet bills, it is necessary to protect your pooch against these critters. Preventative treatments come in a variety of forms, such as topical and oral medications, sprays, shampoos, and collars.

Having all been in the position of trying to regularly pin down a pet to administer medication or give a water-shy pooch a smelly bath, we definitely prefer using collars as an effective flea treatment. They are an easy way to kill and prevent further infestation of parasites, and they last for a lot longer than some other forms of treatment.

How do flea collars work?

There are two main types of flea collars available. The first type works by emitting a gas which is toxic to fleas and other parasites, while the second uses a medication which gets absorbed into your dog’s skin, poisoning parasites when they bite. The top three collars we have chosen are all in the first category as they work without your pooch having to get bitten first.

What to consider when choosing a flea collar

Some of the main points to consider when buying a flea collar are the size and the type of treatment they provide (as mentioned above). You should also consider whether your dog has sensitive skin and needs an organic treatment, or if they are fine with regular treatments.

It is important to choose the correct size collar for your furry friend, as flea collars are designed to be safe for your dog’s skin but not necessarily for their digestive system! This is particularly important for small dogs as a collar that is too big will just slip right off. A correctly-fitting collar should be tight enough that they can’t chew on it, but not so tight that it irritates their skin around their neck. A general rule for a good fit is being able to fit two fingers between the collar and your dog’s neck.

Most effective flea collars use small doses of insecticides to kill parasites. Some of these are safer than others, so we recommend choosing a collar that uses chemicals such as deltamethrin or pyriproxyfen as these have been proven to be safer than other chemicals such as tetrachlorvinphos which can be harmful to both your pet and children.

Organic flea collars are a safer option, but there is a lot of question over whether they actually work and most ‘organic’ products still contain some form of non-toxic chemicals to make them effective. If this is a particularly important factor for you, we suggest you take some time to carefully read the ingredients on different products to find one that is suitable for you and your pet’s needs. Hopefully, our favorite three collars will give you some guidance in finding the best collar for your dog.


Top Three Flea Collars for Small Dogs

Seresto by Bayer

Seresto flea collar for small dogs


Seresto is a relatively new treatment that gives your pooch flea and tick protection for up to 8 months. The small collar measures 15”, but can be cut to size if necessary, and is suitable for dogs up to 18lbs.

Unlike conventional collars, Seresto contains two active ingredients (imidacloprid and flumethrin) which are released in controlled doses and transferred to your dog’s skin and hair to kill fleas and ticks without the greasy feel of topical treatments.

It is recommended that the collar is worn all year round and can even be worn whilst your dog is swimming or being bathed as the collar is water resistant. Regular contact with water (more than once a month) can cause the collar to be less effective and it should be replaced every 5 months if this is the case for your dog.

This collar is slightly more expensive than others on the market but compared to having to wrestle your dog regularly to administer other treatments, we think this is definitely worth it! The small Seresto collar is even suitable for puppies from 7 weeks old, so it’s safe to say this is a pretty universal product.

Organic Way’s 100% Organic Collar

Organic Way flea collar for dogs

Organic Way’s flea and tick collar uses 100% organic essential oils to successfully repel fleas, ticks, and larvae for up to 6 months. The small size collar is 15” and can be cut to size to fit smaller dogs and puppies.


This collar is unique in that it offers a chemical-free protection for your pup, and being eco-friendly and hypoallergenic, it’s safe for humans too. This is one of the cheaper products on the market, which could be due to its shorter lifespan than other collars, but we feel that this is great value for a natural product.


The other notable thing is the essential oils used are extremely overwhelming at first, but they do wear off over time. Having said that, with your pooch walking around smelling of peppermint, lemon, eucalyptus, and lavender, you’ll save a fortune on air fresheners!


Flea and Tick Collar by Earth Vibes

Earth Vibes flea collar for dogs

Earth Vibes have devised a natural flea- and tick-repelling collar which is suitable for dogs with sensitive and dry skin. Coming in a one-size-fits-all length of 25”, this collar gives you the freedom to fit the collar perfectly to your dog and saves you the hassle of having to buy two different collars if your pooch is in-between sizes.

This collar offers up to 8 months of protection and is waterproof, so your fur baby can still be bathed without needing to remove the collar. Despite claiming that this collar is chemical-free, the ingredients list does state that it includes tetrachlorvinphos and methoprene.

However, it is one of the cheapest collars on the market and is an effective flea and tick prevention method so if you’re not fussed about using a completely organic product, this is a great choice. It also smells pretty good too thanks to the citronella and wintergreen essential oils.
