Shae vomited today for the first time...I let her outside today when she went to the door as I usually do. I waited for 5 minutes and open the door to let her in and found vomit on the concrete porch. It was greenish in color. But I have a sheltie outside dog and I thought it might be her cause Shae didn't act sick. Then tonight shae came over to the computer where I was and started whinning. I tried to get her up in my lap and she kept pulling away. So I got up and followed her. She went to the living room and sat in front of the couch and whinned. So I picked her up and sat on the couch with her and she fell straight asleep. After about 45 minutes I got up and laid her on the leather couch and left the room. My husband yelled for me to come back in the living room that Shae had vomited. It was thick yellow yucky stuff. I took her outside for a few minutes and then brought her back in and gave her a drink of water. She seems okay right now..I haven't done anything different...she's eating the same food..science diet..same amt..same time each day..only thing different is a new stuffed animal i gave her to play with yesterday..I took it away from her after the second vomit to see if that has anything to do with it....Any advise on bt having problems with vomiting would surely be appreciated. Thank you..btw she has always had hiccups..from the day I bought her home...is that normal ?....
