Frontline and neurological issues (vet, skin, symptoms, fleas)

[Aptor hours]

Has anybody ever heard of Fontline tick causing neurological issues? My husband and I are just taking random stabs because we Frontlined Storm on Friday and now he isn't using his back leg quite right. It is almost like neuroligical issue. A trip to the vet may be in order

I've seen dog frontline cause seizures when used on cats. I can't think of any reason why frontline would cause lameness in one leg. Sorry.

I hope Storm feels better soon.

I've used frontline on my dog for years without problems, maybe he strained something playing?

Is Storm showing any other symptoms? How old is Storm ?


I know a gal who put Frontline all on the scruff area and her dog had gotten a rash and was itching the area. I was told to apply from the scruff down to above the tail, others may do it different, I've had no problems, I part their hair from scruff to top of tail and that makes it easier to see and apply.

Anyway I'm sure you are taking Storm to the vet, I hope everything works out OK, let us know

I don't like Frontline and would never put it on an animal again. As you can read in my post above it is a nuerotoxin and possible carcinogen.

If you are concerned about fleas, Advantage is pretty safe. If you are worried about ticks and Lyme disease, I think the best bet is the check your dog regularly for ticks and pull them off quickly. Lyme is easy to treat if you catch it quickly -- just put the dog on antibiotics for a month. I consider that safer then putting pesticides on my animals. As far as I'm concerned, it I can't put it on my own skin, I'm certainly not going to put it on my cat or dog.

Woof, I'll assume by your Location "some place very cold" you don't live in the south like I do...we have a MAJOR tick problem here, I've had lymes myself several times.

Frontline works and is recommended to me by a well respected vet who owns and breeds dogs and she also taught at the UGA Vet school.

Even if you treat Lymes it still has really bad side effects - I know from personal experience.

Consider your self lucky that you don't live in our area...you might be re-thinking about using products.

Without Frontline, my dog would have been sick many times over and he is now 16ish and going strong.

We all have to make choices as to what is best for our critters.

I live in the Northeast, where Lyme originated (Lyme, Connecticut). But again, I would rather risk getting Lyme and treating it with a simple course of inexpensive and harmless (relatively) antibiotics then put those pesticides on my animals, especially since I pet them, kiss them, and sleep with them, so whatever is on them is on me!

Of course you should do whatever you feel comfortable with.

Keep in mind however, that with the numbers you quoted above, a 100 lb person would have to ingest 600mg of fipronil a day for it to be considered carcinogenic. That's if it has the same level of carcinogenicity in humans as in rats. A 30 lb dog would have to take 180mg a day (for how long? it didn't say).

Even water in the right doses is toxic.

I agree that everyone needs to make their own decision. However, I've read enough negative news about Frontline to make me feel uncomfortable. You have no idea what the long term effects of the pesticide are.
