K9 Advantix II Flea & Tick Treatment
Words · Craig & Sammy | ASIN B004QMX4YW
“The flea and tick control signal here is about as clean as I've seen — 144 positive out of 145 reviews on that specific theme, which is unusual. The effectiveness numbers are larger and more divided, but the mosquito-repellent benefit shows up clearly too, which matters if you're in heartworm country.”
Important Note for Yorkie Owners: This K9 Advantix II Large Dog formula is designed for dogs weighing 21-55 pounds and is NOT safe for your Yorkie. Your 4-7 pound Yorkie needs the small dog formula specifically designed for dogs 4-10 pounds. Using the wrong dosage of flea and tick medication on a toy breed can cause serious adverse reactions, so always match the product to your dog's actual weight. That said, K9 Advantix II is an excellent veterinarian-recommended brand that provides comprehensive protection against fleas, ticks, and mosquitoes. The topical formula kills and repels parasites, offering your dog protection before bites even occur.
For Yorkies, consistent flea and tick prevention is absolutely essential since their small bodies are particularly vulnerable to the blood loss and disease transmission that parasites cause. The once-monthly application is convenient, and the waterproof formula remains effective even after bathing or swimming. Many Yorkie parents appreciate that K9 Advantix II protects against mosquitoes too, which can transmit heartworm, another serious concern for all dogs. Always consult your veterinarian about the best parasite prevention protocol for your specific Yorkie, especially if they have any health conditions.
