If you have reason to believe your dog ate rat poison DO NOT WAIT FOR MORE SYMPTOMS TO APPEAR. GET YOUR DOG TO A VET ON AN EMERGENCY BASIS ASAP!!!!! Please read this link http://www.dogworks.org/poison.htm as it is an excellent article regarding several dogs and their LACK of symptoms before it was too late. You still have time, but it is NOT WORTH THE RISK in my opinion to wait at all. You will see why in the above referenced article. Rat poison affects the blood system, and it works very slowly, it can take even up to six days before the owner knows there is trouble, and that can be too late. Be sure to tell your Vet what you suspect and get your dog in for treatment IMMEDIATELY if you think rat poison is the cause. I never want to alarm anyone unless a dog's life is at stake, and if you think that he ate rat poison, his life is at stake. I could site you various articles, but hopefully what I am saying and this article will be enough. The only way to make sure if you suspect rat poisoning is to get your dog to the vet ASAP - PLEASE DON'T WAIT FOR MORE SYMPTOMS. Please read the article, and be on your way. You may want to print it out and take it with you to the vet. Also take the box of Decon, if you have it, and any remainder of the poison, or dead rodent that is missing. The more you can bring the better, but if all you bring is your dog, please RUSH. I will be praying for you both, and please let me know how things turn out. If your dog has or had a cough, has had neon green stool, or is bleeding from anywhere (nose, anus, etc.) you are most likely right and your dog ate rat poison. But because it causes internal bleeding and clotting the signs and symptoms can be hard to detect and are not always the same, and do not show up sometimes until treatment is too late. Like I said, you still have time, please, please, please, don't take a chance on something this deadly and hard to detect!
