We recommend storing FRONTLINE Brand Products at room temperature and keeping them sealed in their original packaging. If stored under these conditions, FRONTINE Brand Products will not expire. **Q: If my dog is 22 do I buy up to 22 or go to the second category 23 up?** A: I am in the same situation. I have found that the smaller dose is not effective. But the 23 and up does the trick. **Q: Is this Waterproof** A: Yes, but the product must dry before a bath or swimming. “Waterproof” is also listed on the front of package. **Q: Does it actually work ?** A: We've used this product in the past and it worked, and we live on a corner and have our dogs in the country and camping in wooded areas. If I remember correctly, it won't kill adult fleas, but prevents them from reproducing and I believe the nuts as well. If there's an infestation, or a source of fleas nearby, even a neighbor animal, that doesn't have the flea problem addressed, the flea cycle will continue. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Gets rid of pests *by B***T on January 18, 2026* FRONTLINE Plus has been very effective at keeping fleas and ticks under control. It’s easy to apply, doesn’t have a strong odor, and hasn’t caused any irritation. I like that it provides long lasting protection with just one monthly dose. This has been a reliable product for us and definitely worth the purchase. Your pets will be happy you bought it. ### ⭐⭐⭐⭐⭐ Nice working product *by J***E on March 29, 2026* Easy to use, great price,h my dog will not take $80 tablet for 3 months. Works better. ### ⭐⭐⭐⭐⭐ Excellent product, BUT... *by B***A on December 17, 2008* This is an excleent product, but it is not a miracle worker. In other words, you need to use the stuff properly. (1) this product is water resistant...not soap resistant. So if you use this stuff then go and use some of that heavily perfumes soapy shampoo that msot people use..then you are washign it right off. (2) if you chose to bathe your dog..bathe him/her first then wait 2-3 days THEN apply the product so that it will be distrubited properly. (3) Remember that if you have a heavy flea problem that you need to treat the pet and the environment. You can't jsut put it on the dog and not get rid of the fleas in your house, car, yard, etc.. Yeah it will kill the fleas on him/her, but they will get reinfested with fleas everytime they go back into the flea filled environment. This is the only product that I use for my dog. Of you purchase ANYTHING over the counter (biospot, hartz ::shudders::, etc) then you are wasting your money. Flea dips work, but they only kill the fleas that are on the dog when you bathe him/her. Frontline PLUS is great becasue it keeps killing for up to a month. Also, Frontline Plus has a better range of killing fleas than plain ole' Frontline. The "PLUS" means that it kills larvae and eggs and so much more than adult fleas. IF USED CORRECTLY and ROUTINELY this is an EXCELLENT product!!! I highly recommend it. This product also kills ticks. ## Frequently Bought Together - Frontline Plus for Dogs Medium Dog (23-44 pounds) Flea and Tick Treatment, 6 Doses - Frontline Plus for Dogs Large Dog (45 to 88 pounds) Flea and Tick Treatment, 6 Doses - Frontline Plus Flea and Tick Treatment for Small Dogs Upto 5 to 22 lbs. 6 Treatments --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/2308946-frontline-plus-for-dogs-medium-dog-23-44-pounds-flea](https://www.desertcart.co.th/products/2308946-frontline-plus-for-dogs-medium-dog-23-44-pounds-flea) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-23*
