Triforce Flea/tick/mozzie Squeeze On

[sandgrubber]

I did my two dogs with a squeeze on called TriForce. Active ingredients:

Cyphenothrin (40%) and Pyriproxyfen (2%).

About 24 hours later my older girl (who is big on licking the younger girl) started having seizures. Awful deep muscle spasms, strong enough to cause her to flip onto her side from standing . . . lasting less than a minute, followed by tense muscles and a lot of panting, plus some drooling. Back to semi normal for a five or ten minutes. Then another attack. I wasn't going to be able to drive her to the vets alone cause a spasm in my vehicle would have been dangerous. A neighbor is a vet nurse. She gave me the number of a vet to call. The vet heard the description of symptoms and asked about possible poisons. I told him about the spot on treatment. He concluded that she was poisoned by the stuff and said to wash her thoroughly to get all of the stuff out. I did so and the symptoms disappeared within a minute or two.

I suspect that the older girl licked the pup and ingested a lot of the stuff.

This what I found out about it.

I hope your dogs are OK! I'm pretty sure they're both pyrethroid compounds (at least, I know one of them is), toxic if ingested.

I'm so sorry to hear about your girl and hope she is doing OK.

With ANY of these topical treatments you have to be careful about other dogs licking as they are all pretty much poisonous if ingested.

If you have to, keep dogs separated until the spot on has dispersed. If you have one that loves to lick the others, keep them separated for a bit longer.
