[Prince Marley]

I dont know what to do!? This afternoon i went to take marley for a walk,than when we came back i tried to open the door and there was something wrong with it so i got locked out. Had to call my sister to come pick me up. I got to her house around 12 and wanted to feed marley something but there was no dog food so i cooked him an egg.around 530 marley threw up the egg.Also last night i noticed marley threw up what appeared to be hair a little piece of a leaf and im guessing the toliet paper he got to....i do pay close attention to him but sometimes when we go outside and he puts something in his mouth its such a struggle to get it out and by that time its already gone! But anyways hes laying on my lap right now and i gave him some nutrical. He ate fine this mourning his regular food and he ate a little but of his food when we got home but i think hes not eating because hes tummy upset, He was playing at my sisters than after he threw up hes been layin down....if i put him down and call him over he'll come. Im bringing him to the vet toamrrow i just wanted to know if any of you ever expierenced this before?! Am i over reacting??!!
