We lost a pup two days after using it and it was not a nice death, all three pups became seriously ill and I've had numerous PM's and e-mails from other people whose pups also died or had the same symptoms. We lost one of the other pups 2 weeks after. Luckily one is still alive and a real character, she's wonderful!!!
It may not have been anything to do with the wormer of course, but I will never use it again, just not worth the worry. Used to use it years ago with never any problems.
