I'm sure that you realized that you do not use the collar at the same time as the Frontline. Don't know about the Advantix.

I use Frontline Plus. In times of heavy infestation, my pets still get a tick or 2, but that's what I use and will continue to.

Yes, saltidawg, I used the collar by itself as an alternative to the Frontline Plus and Advantix II, which had lost their effectiveness. But my dog acted quite ill while it was on. It took me a while to figure out that it was the collar that made her act so strange, but I finally made the connection that that was the only thing "new" in her life and when I removed it, she returned to normal (I tried this 2 separate times not wanting it to be true).

BirchPoint,

What do you use for Heartworm Prevention?

I have no experience with Advantix II and certainly can not compare it with Sentinel as far as flea and tick control.

I used only Frontline and later Frontline Topspot for many, many years with my (English) Bulldogs - I used Interceptor for Heartworm Prevention.

I currently use Sentinel for Heartworm and Fleas and hookworm, roundworm, and whipworm. I use Sentinel twelve months a year.

I also us a generic equivalent of Frontline Topspot (Flea 5X). With the warmer temperatures I am seeing, I also apply this twelve months a year.

My Vet approves this regimen for my Greyhound, at his suggestion I stagger the dosing. (I do the Sentinel on the 1st of the month, I do the Flea 5X on the 15th.)

I would be very reluctant to follow advice about either pesticides (such as my approach) or with "natural" treatments without a discussion with your trusted Vet.

As you've found out, once the fleas have come home with your dog it is generally more difficult and requires a more broad approach to get rid of them. In addition to treating the dog, you may well also need to be treating your hoe and possibly even some outdoor areas.

I do wish you success!

for fleas and ticks, i use the Seresto collars. they are pricey but last up to 8 months. used them for the first time last summer and didn't find a single tick on any of my 3 danes.

for heartworm prevention, i use the injectible Ivomec which is a cattle dewormer. i had 3 different vets compute the amount i would need to treat my dogs. been using this (injected into meatballs) for years and no problems. one caveat...if you have a border collie, aussie, collie of any kind, or a dog with merle coloring, this drug can be deadly so BE SURE to check with your vet!!!

I was not aware of the Seresto Collars. Looks interesting.

Over the years, I've read of horrible issues with over- dosing (usually) when using liquid Ivomec. Invariably, these mistakes were due to math errors, simply mis-reading the syringe, or simple carelessness.

Ninapearl seems to have done her homework, but I still would urge you to get the subscription Ivomec or other medicine from your Vet. (I have always used a different drug, but I suspect they are all effective.

I realize that the OP did not initially mention Heartworm, and that I brought it up because one of my two flea pesticides is also my Heartworm pesticide.

Back to fleas, fleas, fleas.
