Thanks for your reply, I think I will wait for more 2 days, if his condition is worse, i will bring him to vet.
I have apply medicine from a pharmacy for his ears today and give him some treats with bonus vitamin.
He's getting better than yesterday: move slowly, close 1 eye, head tilt to 1...
He looks tired, now he usually close one of his eye and sometime tilt the head to the right side. I dont know what's wrong with him T_T
Vet in our country is still not very good. I wonder if you guys know anything about this disease.
Maybe he got ear mites since i have to clean his ear recently...
