How to Apply:
Remove product tube from package. Holding tube with notched end pointing up and away from the face and body, cut off the narrow end at the notches with scissors. While holding your dog with one hand, use the other to apply the solution. Invert the tube, and use the narrow end to part your dog's hair while gently squeezing to apply to the dog's skin. Hold the dog for a few seconds to give the solution time to be absorbed into the dog's coat. When finished, wrap the tube in paper and put into the trash.
Apply one tube as a stripe, starting high on the back of the dog's neck and ending directly in front of the shoulder blades.

Just applied my 2nd application. So far so good, no fleas or ticks.
It is nice to have a product that seems to be working well in a flea and tick infested area of Tennessee without using poisons. My dogs are all over 7 years old, two are over 12 so I'm very. happy to have a safer alternative. Can't beat the price either.

Great product
I was so disgusted by all of the pesticides that I was putting on and in my dog. I looked for an alternative but nothing seemed to fit all my needs. Then I found this! It works, is all natural, doesn't make my furbaby sick, and he even smells nice. It's quite strong the first 2 or 3 days, but then calms to a nice clean lemony smell. Will buy this again!

Okay probably
I didn't get a chance to test it on killing pests. Reviews were showing citrus scent, they sent me I forget what the scent was...but I hated it, & too strong, & my dog hated it..i couldn't washi it off fast enough. So wasn't able to find out if works, was looking for something natural. Oh I think they called it Spice. Yuck. Way too strong.

Works if you apply it correctly
The first couple times I used this it didn't work very well, but then I read that you have to make sure you apply it directly to the dogs' skin. Since I started doing that it seems to work just fine. And it smells way better than the chemical stuff and isn't toxic!

I don't think it works
I love how this stuff smells and maybe it helps some, but I've ground 3 ticks on my dogs in the 3 weeks since I've been using this. I've never tried frontline, but my friends say it works a lot better...I'm so bummed because I hate to use chemicals, but I don't know what choice I have :(

Love that it is natural
I always hated putting on my dog those harsh chemicals, so when I saw this product in the store I decided to try it on my dog. The smell is very strong at first, and it bothers my dog a bit but when the original strong scent wears off she's fine. This product moisturizes her coat as well and leaves it shiny and soft! She smells like a fresh cut orange :)She didn't have it on during the summer so I'm not sure how well it works but I have great hope. I also mix garlic in her food and have flea spray that I might spritz on her towards the end of the month in the summer. But that is because of where I live (urban neighborhood) where there are a lot of stray cats and racoons. It's a precaution I took even with the expensive name brands.

Have used for two years and love it
In addition to applying to your dogs, try squeezing a tube onto a few cotton balls and putting them in your vacuum. Works wonders.

Didn't work
I have 3 dogs. I tried this on all 3 at the same time. It didn't work, so I tried again in 2 weeks. I am still picking fleas off of them. I hate the price, but I will go back to Frontline. Works every time.

Been using this product for over a year. Have had no issues with fleas or ticks. Used other to coals before and wanted to get away from chemicals. The scent is strong for the first day or so but it doesn't bother us. I've been happy with this product and feel good knowing I'm using essential oils on my pets.

Scent is strong for a few days but we didn't find it offensive. Even more, it works. Even on our 60 lb Shepherd.

I much prefer the all natural to chemical. We have used Natural Defense for the last 3 years. When it came time to treat my guys again this year, the usual store we purchase from was no longer carrying it! We ended up purchasing the non-natural type and neither of my dogs can stop itching as it's causing their skin to dry out. Back to Natural Defense for us!
