My lhasa apso puppy is vomitting for 4 days. the frequency of vomit is 1-2 times. i changed his diet to rice + yogurt. But that didnt stop him vomitting. From last 2 days, i stoped the food completely, he is now just on water + iv fluids (around 250ml per day) But he has stopped eating food and not playing but just sleeping.. we did his routine stool + hameogram, blood test, x-ray of adobmen, but all came normal.
My question is what can be the cause of vomitting.
He is completely off food for last 2 days but still vomitted today. i gave him chicken soup ( without chicken pieces)
