So, my little mooey is sick but not sick.....so about a week ago he was having TERRIBLE diahrea (but he was acting fine not lathargic or depressed, still playful and happy)so I brought him to the vet and she gave me antibiotics and told me to give him a plain diet of rice and chicken.....so we did that and the first two days all seemed well, but now he has gone the COMPLETELY opposite way and hasnt poo'ed in almost 5 days. I stopped the rice after he didnt poo for 2 days and still nothing. Once again he isnt acting sick or lathargic or anything he just isnt pooping or even trying to. I am kinda worried, has this happened to anyone? Should I go back to the vet? Someone give me some insight, TIA
