Thank you for taking the time to warn folks. Very sorry you lost your dog , must have been a horrible experience. As cools said, some very sick people around .Dogs are so quick too even on the lead. My dog has been off colour with a swollen tummy and the vet said he had probably been eating something he shouldnt , so he's been on the lead all this week , yet even on just a quarter of his flexi, this morning he grabbed something that was in the grass and chomped it before I could stop him. Short of muzzling , avoiding grass, or keeping a very short lead, its almost impossible to protect them every time.Fortunately , he's still ok at the moment.
