well i think if it was going to have hurt him it already would have so you probably did the right thing making him poo but now the other problem>> all i can tell you to do is DO NOT LET HIM DEHYDRATE!! give him plenty of water to drink and clean up his messes ( sometimes dogs go back to what they did and sniff or *gag* eat it SOMETIMES!!!!) but i will eb thinking of him and ur brother and for them both tp get well!!
