The Seresto Small Dog Flea & Tick Treatment & Prevention Collar is designed for dogs under 18 lbs and offers a convenient and long-lasting solution for flea and tick protection. This vet-recommended collar uses the active ingredients Imidacloprid and Flumethrin, which start working within 24 hours and provide up to 8 months of continuous protection. This extended duration is a significant advantage, reducing the need for frequent replacements.

Additionally, the collar is unscented and non-greasy, making it hassle-free and easy to use without causing any discomfort or mess for your dog. It is also adjustable, ensuring a comfortable fit for dogs as small as 7 weeks old. The collar features a safety mechanism that helps in preventing any potential choking hazard by loosening if excessive force is applied.

While the collar is water-resistant, it is not completely waterproof. This means that it can handle some exposure to water, but prolonged submersion could reduce its effectiveness. Some users have reported occasional skin irritation in their pets. Although the collar is allergen-free, it’s best to monitor your dog for any adverse reactions, especially during the initial use. The Seresto Small Dog Collar is a reliable choice for pet owners seeking an effective, long-term solution to protect their small dogs from fleas and ticks, but attention should be given to possible skin sensitivity and water exposure limitations.

Most important from
41666 reviews

Duration of Effectiveness
These collars are worth every penny, offering long-lasting protection and comfort without any noticeable irritation.
Adjustability and Fit
The collar's design makes it easy to put on, with no chemical scent and adjustability that cats quickly get accustomed to.

The Seresto Cat Flea & Tick Collar offers a solid solution for cat owners looking to protect their pets from parasites. With active ingredients like Imidacloprid and Flumethrin, this collar is effective in killing and repelling fleas and ticks for up to 8 months. One of the main advantages is its quick action; it starts working within 24 hours, and pests don't have to bite your cat to be affected. This reduces the risk of irritation and potential diseases spreading to your pet.

The collar is also unscented and non-greasy, making it hassle-free and easy to use. Its adjustability ensures a comfortable fit for cats of various sizes and ages, starting from 10 weeks old. Safety features include a design that allows for a breakaway in case the collar gets caught, which reduces the risk of choking or injury.

However, while the product is highly effective, it may not be entirely waterproof, which means you might need to remove it during baths or if your cat gets wet frequently. The cost might be on the higher end, but considering the duration of effectiveness, it could be seen as cost-effective in the long run. The collar comes in a pack of two, providing additional value. This product is ideal for cat owners looking for a long-term, low-maintenance solution to flea and tick prevention.

Buying Guide for the Best Cat Flea Collars

Choosing the right cat flea collar is essential for keeping your feline friend healthy and comfortable. Flea collars are a convenient and effective way to prevent and treat flea infestations. When selecting a flea collar, it's important to consider various factors to ensure it meets your cat's needs and provides the best protection. Here are some key specifications to look at when choosing a cat flea collar.
Active IngredientsActive ingredients are the chemicals in the flea collar that kill or repel fleas. This spec is important because it determines the collar's effectiveness and safety for your cat. Common active ingredients include imidacloprid, flumethrin, and pyriproxyfen. Some collars use natural ingredients like essential oils. If your cat has sensitive skin or allergies, you might prefer a collar with natural ingredients. For severe infestations, collars with stronger chemicals may be more effective. Always check with your vet if you're unsure which active ingredient is best for your cat.
Duration of EffectivenessThe duration of effectiveness refers to how long the flea collar will continue to protect your cat from fleas. This is important because it affects how often you need to replace the collar. Flea collars can last anywhere from a few months to up to 8 months. If you prefer a low-maintenance option, look for a collar with a longer duration. However, if you are dealing with a severe infestation, you might need to replace the collar more frequently to ensure continuous protection.
Water ResistanceWater resistance indicates whether the flea collar can withstand exposure to water without losing its effectiveness. This is important if your cat spends a lot of time outdoors or if you bathe your cat regularly. Water-resistant collars are designed to remain effective even after getting wet. If your cat is mostly indoors and rarely gets wet, water resistance might not be a crucial factor. However, for active or outdoor cats, a water-resistant collar is a better choice to ensure continuous protection.
Adjustability and FitAdjustability and fit refer to how well the flea collar can be adjusted to fit your cat's neck comfortably. This is important because an ill-fitting collar can cause discomfort or even injury to your cat. Most flea collars come in one size that can be adjusted to fit different neck sizes. Make sure the collar is snug but not too tight, allowing enough room for two fingers to fit between the collar and your cat's neck. If your cat is still growing or if you have multiple cats of different sizes, an adjustable collar is a versatile option.
Safety FeaturesSafety features are design elements that help prevent accidents or injuries while your cat is wearing the flea collar. This is important to ensure your cat's well-being. Some collars have a breakaway feature that allows the collar to snap open if it gets caught on something, preventing choking or strangulation. Others may have reflective strips for better visibility in low light. If your cat is very active or spends time outdoors, a collar with safety features is a wise choice to minimize risks.
