Directions: How to apply the Seresto collar on your dog 1. Remove the collar from its packaging. 2. Unroll the collar and remove the small plastic connectors from inside the collar, ensuring that no remnants remain. 3. Insert the end of the collar through the buckle and loops. 4. Adjust the collar around your dog's neck until it fits comfortably on them. 5. Two fingers should fit beneath the collar and neck to ensure it's not too tight. Any excess length of the collar beyond an inch past the loops should be cut off, unless it is on a growing puppy, where some additional length may be needed for adjustment as the puppy grows. 6. Check periodically and adjust fit if necessary, especially on growing puppies.

  • Budget price and worth it.
Size: 1 Pack
One of the first things that caught my attention was the price. After comparing prices at several major retailers like Walmart, Target, Petco, and Pet Supplies Plus, I was thrilled to find that the Seresto collar was significantly cheaper. This was a huge win for me, especially since I have three dogs to care for. Finding an effective flea and tick treatment at such an affordable price made a big difference in my budget. But affordability aside, the performance of the Seresto collar is truly impressive. It provided long-lasting protection against fleas and ticks, giving me peace of mind knowing that my dogs were safe from these harmful pests. I no longer have to worry about potential infestations or the health risks associated with flea and tick bites. Another aspect of the Seresto collar that I appreciate is its convenience. Unlike topical treatments that need to be reapplied every month, this collar provides continuous protection for up to eight months. This means fewer trips to the store and less hassle for me, which is always a plus! Furthermore, the collar is water-resistant, so I don't have to worry about it losing its effectiveness after my dogs take a dip in the pool or play in the rain. Its durability and effectiveness make it an excellent choice for busy pet owners like myself. Overall, I highly recommend the Seresto Small Dog Flea & Tick Collar to anyone with multiple dogs or even just one furry friend. Its affordability, effectiveness, and convenience make it a top choice for flea and tick prevention. Thanks to Seresto, my dogs can enjoy the great outdoors without the worry of fleas and ticks tagging along! ... show more

  • Worked on 7lb Papillon when Advantix drops did nothing
Size: 1 Pack
I have always used K9 Advantix on my dogs, and never had problems until the year I started camping in Northern Wisconsin. Now, let me just say -- the K9 Advantix worked PERFECTLY on my large-breed dogs - never a single flea or tick. Knowing that we were heading into a tick-infested area, I put the Advantix drops on my 80 lb german shepherd and my 7 lb papillon a week before camping. After a walk in the woods, I found one tick clinging to the outside hair of my german shepherd, not attached -- easy to just flick right off before we went in the house. We didn't find any ticks on the papillon until we went home. First found one tick within 24 hours, had to remove it with tweezers but figured, hey, maybe it hadn't attached long enough to get killed by the Advantix. Then found another after 24 hours. And another after 48 hours (by that time it was engorged). Clearly the Advantix was not working on my papillon, though it seemed to be working on my large breed dog. Perhaps the drops, being such a low quantity due to his size, didn't absorb properly. But I wasn't about to joke around with ticks and lyme disease, so I started looking for alternative options. The day before I ordered the Seresto collar, my dog picked up a tick in my own backyard, in the city of Milwaukee, with mowed grass and everything. That was it - I was going to risk my fear of collar side-effects, watch my dog carefully, and get this collar. Fast forward 10 days after wearing the Seresto collar. No side effects (I checked FREQUENTLY for signs of rashes/redness/lethargy/hair loss), and we found a dead tick (not yet engorged) dead in the house. I'm convinced it was the Seresto collar, given that the small dog is the one who already picked up 4 ticks, while the larger dog barely picked up one. The large dog is still using up what's remaining of my K9 Advantix, but I'm likely to switch her to the Seresto collar next year. The convenience of having one collar for the whole non-winter season, the fact that it seems to WORK on my small-breed dog, and the cost per month for the collar vs the drops has sold me. I think the drops work fine for large breed dogs, but can fail due to miniscule dosage amounts on smaller breeds. The collar is safer for my dog when it comes to lyme disease, compared to the risk of side effects (which you should be on the lookout for with both drops and/or collar during the first few days of application -- anyone can have a reaction to medicine if they're allergic). Seresto has sold me on their collar -- now all we have to do is repeat the camping experience and see how long the collar lasts. Happy camping! ... show more

  • Convenient and Long-Lasting
Size: 1 Pack
After using the Seresto flea and tick collar for 6 months, I’ve noticed a significant reduction of fleas on my dog. The collar was easy to adjust, and my dogs didn’t seem to mind wearing it. There was no irritation or itching, which is a plus for dogs with sensitive skin. While the price is a bit higher than topical treatments, the fact that it lasts for 8 months makes it a great value. The collar is also water-resistant, so my dog can still go for swims without it losing effectiveness. Overall, I’m happy with the Seresto collar and would recommend it to anyone looking for a convenient and long-lasting flea and tick solution. ... show more

  • The only thing that worked.
Size: 1 Pack
I believe it was in 2016 that we were having super flea problems! We were trying everything from spraying the yard to drops, pills and baths. The vet said that everyone was having issues. It was sad seeing fleas on our little dog! I’m not sure if we just gambled on these collars or the vet recommended them but oh man what a miracle! All bugs were gone. Pros Takes care of your normal day to day fleas and ticks. We buy one collar a year and lasts until we need a new one. We live in northern Indiana so you have to take that into account. Package says 8 months. Cons It’s a little pricey but also it’s one and done each year. When we go hiking in the woods we have to get ticks out of their hair when we are done. That’s the only reason it lost a star. Conclusion Buy it use it and then don’t worry about it until next year. Just double check your dog to make sure they don’t have an allergic reaction. You can see the grey collar in the second photo. The first photo is so you can enjoy my cute dog! 🐶 Happy flea and tick free home! ... show more
