My Poor Puppy

My dog is about a year and a couple of months old.. Every morning I take him out to pee...then he goes in his crate until i get home (unless Dh is home and he usualy is) but this morning he WOULD NOT go..and i was late for work and DH went to work with his brother for some extra $$ and i feel terrible, i keep thinking that hes sitting there holding it in... what should i do,.. i want to leave but since i only started this job in Dec.16tth.. i dont want to have to leave already, and DH's cell is must be dead cause i cant get through.. i am feeling horrible!!
