Review: Quality Product - This product is less expensive than Frontline, but has worked well on my 3 Life Stock Guardian dogs. They are exposed daily to ticks and fleas. I have found no fleas or lice and only dead ticks on the dogs.

## Questions & Answers

**Q: Has anyone used this product in the Pacific Northwest and had any luck?**
A: Its awful, I put it on two of my dogs and they scrached and itched for months.  I was beginning to worry, but after 4 months they stopped.
Do not buy this product.

**Q: What do you recrecommend for heartworm prevention**
A: My Dr give the medication

**Q: fluralaner what product contains this?**
A: Please do not use this product. It does not work and it's poison for your pet, spoken from experience. I used it and was not happy, neither were my dogs. I currently bathe my dogs 1x per week with dawn dish soap, just lather and leave on for 3 min. Rinse and fleas are dead. No more fleas since starting this routine. I urge you to Google the dangers of these products to your animals since so many pet owners are not made aware. Best of luck .

**Q: “I put this on my dogs and cat last night and still itching like crazy. How long until it works??”**
A: I would recommend Capstar (nitenpyram is the active ingredient) to immediately get rid of fleas. They'll all die within in 24h and then the topical can then be used as a preventative. 

Also, my dog actually got fleas while on the TevraPet FirstAct Plus product. My vet told me that fleas in our area are resistant to Tevra and Frontline and recommended the Capstar and then using the Bayer Soresto flea collar, which lasts for 8 months. No more fleas at our house!

The product was simple to use. Open vial and apply to dogs back.

### ⭐⭐⭐⭐ My absolute go to for fleas
*by R***G on March 14, 2025*

I have tried ALL the "generic" Frontline on here. This is by far, the best one. The Amazon brand made several of my cats lose fur and break out. Smelled absolutely horrible like a fishy scent. This one did not. The others only keep fleas off for about 2 weeks and did not kill eggs because I kept finding teeny ones. Like fresh hatched. This one worked and killed all fleas. Lasted a month and did not smell strong. Will keep buying. Just like Frontline at a better price. (
