Veterinarian said not to use

1 day ago
I purchased without looking at the side effects . Once I received it I realuzed it can cause seizures. I consulted with my Veterinarian he did not want me to use this product because of the risk of seizures. Lucy had seizures in the past. So I didnt want to risk it. Unfortunately Petco refused to except a return.

No, I do not recommend this product.

Flea season has been tough this year! While this product helped a little, it didn’t stop the fleas after about a week. We have yet to find a product that really works this year.

Very disappointed and concerned.

Mamas Mama

1 month ago
I bought this for my dog Mamas last week and it says fleas should be dead in 12 hours. I applied it and waited to get her wet, according to the instructions. She didnt have many fleas to begin with, as her last chews were just starting to wear off, but we are on day 5 now and I’m catching fleas jumping from her to me! I also, like an idiot, didn’t research this at all before buying. Never making that mistake again. The guy behind the counter highly recommended it and I was eager to get some relief for my fur baby. Recent reviews say the formula has apparently changed and made it ineffective. I’d have to say that’s true! However that’s not the most concerning part. I’m keeping a terribly close eye on her now, after reading the hundreds and hundreds of reviews talking about their dogs having SEIZURES and bleeding, irritated skin, which shows up hours to days after application. Mamas keeps trying to bend back and bite where I put the medicine but she can’t reach… I’m sure she’s uncomfortable. And I’m actually terrified right now. This stuff not only doesn’t work but could really really harm your dog!! I’ll shell out the extra $ for the chews because at least those worked! I’ll be attempting to return the second tube it came with.

No, I do not recommend this product.

Does it kill/ repel tapeworm ?

    2 years ago

    I applied K9 Advantix II for small dogs (4 - 10lbs) to my toy poodle. He's oatmeal color fur. After the application, we noticed his fur on his back where the three spot applications were, turned grayish brown in a strip. What to do with the discoloration?

    1. 2 years ago
      Give your dog a bath no less than 24 hours after application. The stripe will go away and they'll still be protected. For the medication to be effective, they can't get wet for 24 hours application. The topical does pick up dirt and fuzz, but after you bathe them it will be gone.

    I have a 50 lb pit bull. Looking for good flea protection. He scratches often. Would advantix work?

    1. 2 years ago
      Advantix also repels pests.  Most flea treatments only kill fleas when they bite.  So Advantix may work for your dog.

        What is the best one for a 8 week old German Shepard puppy?  Do I just got by the weighed when purchasing? 

        1. 4 years ago
          If possible, go to the store and ask a qualified assistant for your first purchase. It is determined by what your dog weighs, that is correct.
