Fleas returned on my small dog after K9 Advantix. Safe to re-treat?

No, if you are seeing fleas I would encourage treatment. I recommend using a different product with a different active ingredient from k9 Advantix. You could use another topical such as Revolution, or an oral product such as Nexgard or Bravecto. I hope this helps!

Can I buy K9 Advantix for my small dog at Petco for flea prevention?

I'm not sure if they do or not - in the United States, it's available at most pet stores and even some large, "general" type stores like Walmart. I would suggest calling or visiting your nearest pet store and/or any large grocery stores in your area to see if they have it :)

Choosing flea, tick, heartworm meds: Revolution, Advantix, Heartgard?

Congratulations on your new dog! I like Revolution if you are looking for a topical product. It consistently works well and is well tolerated. If you like the idea of an oral product better, I like Trifexis (it’s another all in one product). Sometimes though the pets can smell the Trifexis and they won’t eat it. In that instance, I like Simparica and Interceptor. My personal preference is oral products. I hope this helps and please feel free to post any additional questions.

My dog has fleas. Is K9 Advantix effective and how do I apply it?

Yes K9 Advantix is a good product, I recommend it. You don’t need to bathe Noble first, just apply it. You will have to disinfect your home as well, fleas live in the environment not on the dog. I hope this helps!
