Sara, I'm glad Carl is feeling better, but I suggest strongly that you get him back to the vet and start Vitamin K shots NOW! Decon poisoning is how I lost k'Treva last year and she acted perfectly normal for almost two weeks before it nailed her! By the time I realized how bad it was, it was worse and she died. The Vitamin K is to help clotting and will counter the effects of the Decon. But you need to start it now. If it was a seizure, the Vitamin K shouldn't have any adverse effects, but if it was the Decon, it is really important that you do something now. The anti-coagulent (SP?) is coumadin and is used for thrombosis patients and people with blood clots, etc. and it will cause a dog to bleed to death internally if not dealt with immediately! Please, at least talk with your vet about the possibility and see if he/she won't go ahead and do the Vit. K and see how it goes for a couple of weeks. Better safe than as sorry as I am for not doing something for Trev sooner!
