soresto collars are killing dogs nation wide don' t use it
got a link?
No, because there's no factual evidence(at least that has been released) of any of the sort. It typically works out like this: "I put a Seresto on my dog and he ran out in traffic and got hit = Seresto killed him" or, "I put a seresto on my 14 year old lab and 6 weeks later it died of liver cancer, Seresto killed my dog" Effect erroneously linked to causation.
