My 4 year old Chihuahua who sleeps under my bed threw up twice just right now but he seems fine? It's either cause I give him too much snacks or sometimes he eats my cat's food but idk. He just woke up out of no where and threw up like whitish yellow. I dont know if it's Parbo. He never got sick in his life just worms when he was a pup but thats it?
