Haven’t seen any fleas/ticks
I live in a wooded area. This actually works for our mini labradoodle. We make sure that we put it on him the same time every month.

We NEVER have fleas. Ever.
I’ve used this on all my dogs for about 10 years now. Every dog responds to it the same and we never have fleas, ever! My dogs don’t itch until just about when I need to reapply. That being said when I brought in a new flea bag riddled with ticks and fleas, it took about a month to rid both dogs of them using this and shampoo because they were everywhere in the house! We literally have not had fleas in our home for about 8 years and it’s amazing! Btw we lived in FL then SC and now NC if y’all are worried about the climate.

Affective on our short haired dog
We use this on our short haired dog as it penetrates well and soaks the skin. It might not be as affective on our long haired dog but we have never tried it. The only draw back is our short haired dog has a greasy streak down the back for a couple of days but she is free of fleas.

Good product for a great value
I like this brand very much. I have used it for about six years. The price is a side benefit, which makes it an excellent product for two reasons.

No good! Not even a little.
I dunno if what I received was just old or what the issue was, but I bought it because the reviews I read seemed positive. I’ve used this for years. (From Walmart) it usually works great. This was literally the equivalent of pouring water down my two dogs back. That’s another thing…if it were a fluke n it was only one bad tube ok. But, it did nothing for both dogs with either tube Needless to say…and no offense-because it’s apparently working somehow for some according to reviews. I just don’t understand how. I would never use this again and definitely wouldn’t recommend it. Sorry! And that’s me trying to be kind. Because now my dogs had to wait on it to get here wait 2 days before a bath and I waited 5 total instead to see if it was gonna begin working. So, a total of a week n 1/2 to 2 weeks being eat up by fleas because of it. My female has red blotches all over her stomach from bites and has dug herself raw. I’m actually pissed. But, trying to also keep it respectful!
