I have bought this product many, many times and will absolutely continue to do so for my girls Ruby and Jade. If you live in Texas, you already know the bugs here don’t play around — especially the mosquitoes. These things keep all the thugs off my dogs. Fleas, ticks, mosquitoes… not today. 🚫 Ruby and Jade have zero issues while using this — no reactions, no irritation, no problems at all. It’s easy to apply, works exactly like it’s supposed to, and gives me peace of mind all summer long when the bugs are at their worst. I’ve tried other products over the years, but I keep coming back to this one because it’s reliable, effective, and consistent. When something works this well and keeps my dogs comfortable and protected, I’m sticking with it. If you’ve got dogs and live in a buggy area (or just want the creepy crawlies evicted), this is a must-have. Ruby and Jade approve 🐾🐾 — and so do I!
