That's really disappointing. My dog can't wear the collar anyway because he takes an SSRI, but my parents use those collars as one of their Aussies started having seizures while on the flea/tick tablets he was taking. I wonder what they'll do now.

 

Hopefully, if proven true, Seresto will be removed from the US market. This has been going on for quite a while and hopefully there are other products in the works. I also saw a tidbit somewhere that Seresto could also be harmful to humans.

I figure that the 2500 number is understated since many do not have a PM done after their dogs pass.
