My 4 years old male Japanese Spitz always has a sensitive stomach, he used to throw up yellow liquid once a week then it changed to once a month after I started giving him kelp a year ago.
However, recently he started to throw up food about once a week 2 hours after his dinner, no change in his diet or living environment, since he’s a bit overweight his dry food is also his treats. I went to the vet 10+ times when he used to throw up a lot and sometimes with diarrhea, unfortunately no findings as to why, vet said could just be sensitive stomach. Anyhow, just about 3 hours ago he threw up his dinner again then an hour later he had very small patches of soft stool with very little blood attached I observed.
Anything I can do to help his sensitive stomach? Should I be concerned that there very little blood in his stool? His blood work always came out nicely, did ultrasound, x ray 2 years ago with the same problem we had just now, all looked positive.
