When I took Chloe and Kylie in to get spayed I was so upset. Thankfully our vet is a family friend my father grew up with. The vet said after I left he went to get them out of their carriers and Chloe my yorkie had already pried her bag open and was sitting out beside her bag as if to say no way jose catch me if you can!
I felt terrible and very nervous waiting for my babies to come home. They were so out of it my roommate and I just held them all night long. They were just fine in the end and I am sure that your baby will recover quickly too! Good luck!
