Review: Worth it!! - Love this! No more bites, keeps all the bugs off my dog, no side effects found, no hair loss , bit pricey but worth it, cut open in a rounded shape so you don’t scratch dog when applying, cut, squeeze and done. Wrote date on box. Will continue to buy for start of spring to first snow. I put on back between shoulder blades and on top between hips just above tail so he can lick at it. Easy to squeeze and use
Review: Flea Meds. - Works well for both of my dogs. I have never seen any fleas on my dogs and they don't get any adverse reactions to it.

### ⭐⭐⭐⭐⭐ Read instructions all the way first
*by D***E on June 25, 2026*

We've used frontline forever, and we're recommended this version due to the outbreak of ticks in our area. If you don't apply at exactly as instructed it can leave a slimy patch on the dog that lasts over a week. Other front line fully absorbed in a day. Make sure you're getting it all the way down to the bare skin and spreading it out along the whole back of the dog. That being said ticks die real quick when in contact with the dogs
