It works!
July 22, 2023
We’ve been using this for years, and haven’t seen a flea and hardly any ticks in all that time. It really works!
  • It works really well and is easy to apply.
  • Quite pricey

Great product that protects against fleas, ticks, and mosquitos
September 16, 2021
I have been using this product for years. It is the only one I could find that would protect my dogs from mosquitos in addition to fleas and ticks. However, this is super dangerous for cats. If you have one more more cats that cuddle or come into close contact with your dog(s), make sure you do NOT allow that to happen for at least a few days after using this product.
  • Great for protecting dogs against fleas, ticks, and mosquitos.
  • Terribly dangerous for cats and could have severe consequences if applied to a cat or if a cat is allowed to come into close contact with a dog after using this product.

We have been using this on our two lab mix girls for years and it has done a great job for us. I know there have been other products introduced in recent years but we just stick with K9 Advantix II. No reason to change if it works.

I purchased 2 years worth for my 2 Springer Spaniels. Unfortunately the return policy is 30 days from purchase. I'm 60 days in. I've tried 2 applications and I find fleas all over my dogs. This stuff doesn't work at all. Not satisfied. Will never purchase again. I do not blame entirely pets. I actually love the company.
  • Does not do a thing to combat or prevent fleas.

What a deal!
September 5, 2020
I look Online for the best deal on flea and tick products I use for my dogs. And with 5 basset hounds, why pay more than you have to. I was delighted to find K9 Advantix II so reasonable. I don’t know how other sites can charge so much more for the same thing. I will definitely be shopping here again.

Merchant Response:We are glad to have you Basset M. If there is anything more we can do for you just give us a call.

Excellent purchase
April 3, 2020
One of the few products I could find that treated fleas ticks AND MOSQUITOS. TOPICAL I thought it was going to be a chewable. Delivery took about a week. Works well on my 63 lb. dog (considered X-Large). No problems. Make sure to get it on the skin under the fur. Very well priced, vet is much higher. Thank you.

Great! Thanks!

We've been using K9 Advantix II Blue for years. Never any kind of bug on either of our Goldendoodles. Sure wish I could get a product at that price, works that well, and not be greasy on my two beautiful Golden beauties.

It really works very well. I don't have any problems with ticks or fleas. I have a Siberian Husky who likes to spend all the time she can outdoors. I have never had a problem. She has a double coat. This is a great product.

2 Month K9 Advantix II
April 6, 2016
I have been extremely pleased with this product for several reasons. First of all, it does an exceptional job at repelling ticks, fleas, and mosquitoes. It's worked well for her for a number of years----I wouldn't have her use anything else to repel those types of pests. Secondly, the prion diseases f being able to purchase just a 2-month supply rather than the standard 4 or 6 month supply like other pet websites is awesome!! Thirdly, the price is great, but because I was a past customer, I got a promo code to give me a discount on top of the already great price! I just can't say enough good about Entirely Pets Pharmacy online!

Product seems to help.
November 26, 2015
We still get ticks on the dog but it seems to help repel more of them and they die before they burrow deep in the dog,
  • Does keep the tick population down on the dog and helps keep them from burrowing in.
  • The dog does not like when I put it on him and I wish I didn't have to put chemicals on him that absorb into his skin but I guess it's better than having tons of ticks on him.

A must for anyone in the north woods of WI
November 26, 2015
The ticks are terrible in the spring up in Northern WI This year I hardly found any ticks on my dog so I believe this product worked.
  • Product seems to help keep the ticks from burrowing deep on the dog.
  • Doesn't really repel the ticks but keeps them from burrowing in deep. Also, seems to bother the dog when I put it on.

I had just moved and the change of address was causing havoc in many transactions. Entirely Pets was patient and caring through all of this. It meant a great deal. I am deaf so can't use phones so we relied on emails and they hung in with me and it worked. Many thanks! Bravo!!!
