Thank you everyone, Pixie is doing well today! we just got back from the Vets and after some blood work, everything was normal. She looked up her nose and in her ears and down her throat. Her throat was very irritated but she felt that the grass irritated her throat, and the vomiting.
Pixie threw up about 3 times last night and after the third time there was a lot of flem. She stopped reverse sneezing! Weird Maybe she had grass stuck in her throat.
Final diagnosis at the vets: Pixie has allergies and when she goes outdoors to play I am to give her 3ml of childrens liquid Benadryl. NO GRASS EATING!!
lol I try to stop her she is like a grazing cow
The vet thought that maybe the little bit of chocolate she ate made her throw up and she got rid of what was causing the reverse sneeze. She said that the 1 m&m was not enough to get chocolate toxity but enough to cause her throw up.
She is on a bland diet for 7 days to give her system a break. Thank you every one for your prayers.
