My dog suffered from chocolate poisoning....?

This isnt really a question but I would just like everyone to know that chocolate really is very toxic to dogs. Last week, I was in the hospital having surgery. Since my husband was there with me, We hired a trusted dog sitter that we have used for years. We have never had any problems with her before. When I got home a couple days later, everything seemed normal. After a few hours of being home, I noticed my 3 year old, 10 pound mini dachshund was losing control of her bladder. She was peeing everywhere. I figured Id take her outside. Within 10 minutes of being out, she had rolled over onto her back and was shaking uncontrollably. My 1st reaction was that she got stung by a bee because she did the same thing last year when that happened. My husband went inside and got a benadryl for her. This did not help so we took her into the vet. The seizure lasted about 10 minutes. The vet didnt know what was going on but bloodwork and an exam came back normal. The vet sent us home and told us to just keep an eye on her. Come to find out, The dog sitter said that my dog had got into her purse and ate 2 Hershey bars. I called the Vet back and she said that the coma and death is usually caused by the seizures lasting too long and my poor dog wasnt to far from death. She is doing fine now, although she now weighs 12.3 pounds (2.3pound weight gain from the chocolate). Please, Never allow your dog to have ANY chocolate. I would hate for anyone else to have to go through this.
