My wife and I have noticed over the past two years that our dachshund will vomit almost exclusively in the evenings around the same time maybe once or twice a week. It is always yellow bile and has a copper smell to it. It is usually preceded by him swallowing excessively and acting very urgently to get outside. Once in the yard he will eat grass hurriedly until he barfs. After he vomits he is fine.
We have taken him to the vet for this multiple times and they've done x-rays and blood work and find nothing unusual or out of the ordinary. He is not overweight. He does have horner's syndrome although it flares up very rarely (less than five times ever in his life and never for more than a few hours).
He has had the exact same kibble his entire life. He is 7 this year. We typically feed him once in the morning. I've tried varying his food schedule to see if maybe he is vomiting because he is hungry. Sometime this seems to stave it off for awhile but inevitably he will vomit again.
A few things to note:
- We moved houses in the last year, but the vomiting was happening before that
- My wife and I are both very anxious people by nature. Something terrible happened to us in the last year that made our anxiety even worse. I'm not sure if maybe he can sense that and it is driving him to vomit more.
I would appreciate any suggestions or advice from folks who have experience with weiner dogs. I've had one other before our current pup and he never did this.
