answered question 2/8/2010 My Dog Won't Urinate Or Have A Bowel Movement. What Could It Be? He was hit by a car and that was a day ago.I don't have money for a big vet bill.he justs lays around,I bring him food/water but havent seen him go to the bathroom yet.I don't know if its because he don't want to go in the house or because he can't.
