I am devastated at the sudden death of my beloved chihuahua Chalupa. She died on Friday July 15,2011. I had taken her to the park with my other two dogs. She was actually walking around alot more than she usually does. She was going to be 12 years old next month on the 24th. I was sitting on the picnic table looked over at her and she had her head in an odd position I called her name and she suddenly collapsed foam coming from her mouth and seizing. I picked her up and rushed her to the vet as fast as possible. When I got there she was still in the same seizure still foaming at her mouth. The vet came out maybe 5 to 10 minutes later and told me she had passed. That her heart stopped, they did CPR and couldn't get her to come back....This chihuahua was like no other. She was the sweetest most laid back chihuahua ever. Everyone loved her especially me...I am sooo devastated and I feel as if a piece of me is gone....They feel she could have possibly had a stroke since she was usually sedatary and now was walking alot...It was just suppose to be such a great day that ended in complete devastation. I don't think I can ever think about ever replacing her...She was too PERFECT...Thank you for listening...RIP my Princess Chalupa...MOMMY LOVES YOU FOREVER!!!
