Bayer II Flea and Lice Treatment for X-Large Dogs, Over 55 lb, 4 doses

I've been using Advantage for flea control for several years, and Amazon is one of the best places to get it. You can't beat $10 a month for large dog flea protection. I also use one tube split into fifths (via syringe measurement) to give to my cats. Advantage II specifically is exactly the same product, in different dosages, for both dogs and cats. My 70-lb Lab gets a full 40 ml tube by herself, then the cats get 8 ml each and my brother-in-law's two ferrets get 4 ml each. I can cover 7 pets for $20 a month- a fantastic deal.The Advantage makes a noticeable difference in my pets' comfort- towards the end of the month, when it's wearing off, they begin to get itchy and uncomfortable. Once I reapply, that stops within a day or two, and they're happy and flea-free again all month.I have noticed that if our dog regularly gets into water (pool, beach, sprinklers), the Advantage wears off much quicker, despite claiming to be waterproof. That's understandable in a topical treatment, so we try to keep her out of water until the end of the application cycle, before a new treatment- then she gets to get wet to her heart's content!If you need to bathe your dog to kill fleas before applying, be sure to wait a day or two after the bath to give your dog's natural skin oils a chance to bounce back- it helps to distribute the medication.Be aware: this product is alcohol-based, and will evaporate quickly if left out in open air (we use a glass baby food jar to split the dosages in the syringe). It has also stripped the lacquer off the dining table when a few drops spilled while splitting doses, so try to avoid that too! Other than that, Advantage II is, in my opinion, the best topical flea control.

This flea meds is the best! I tried another and it didn’t last but a week! This stuff is amazing!

Left package where I wanted it placed. Good Job

I have 9 cats and 1 corgi dog that weighs in at 30 pounds. I was looking for something that would be cost effective and safe for both cats and dogs, in the proper dose. My vet taught me how to dose the product out for the different weights of my animals and that has saved me a lot of money while keeping my fur family healthy. The chemical that is in this product started out working very well. Over the years it seems to be losing its effectiveness earlier each month. The fleas would start dying off and the animals would be comfortable all summer, with uninterrupted application. Now they will be back to itching after 2 weeks. In addition, some of the cats have developed lumps at the application site. I have a couple that are sensitive to the chemical and would foam at the mouth....we had to adjust the "standard" dose down. There is also the smell....it is all consuming and fills the whole house, lingers on your hands and furniture and leaves their coats greasy looking at the application site.Despite what sounds like negative aspects, the product worked for years and is better than being flea infested!! I am sad that it's loosing effect, so I have switched to a different product with a different chemical. Perhaps alternating chemical treatments from year to year would stop the fleas from building a resistance to one product??

This is the ONLY brand I trust and will ever purchase. The formula is effective pretty quickly. My animals can't stand when I apply this to them but it is the only brand that I have found to ever kill and get rid of fleas completely, I've tried so many too! I use this on my ferrets too, but super carefully! I drip the formula into a glass vile and use a mL syringe. I've adopted many ferrets infested with fleas and this is the only formula that has ever successfully killed the fleas. It doesn't burn them, but they must be separated until it's completely dry or else they may get it in there mouths from playing with each other. Overall great product and a must-have in my home!
