This is the third day without Atlas — Apollo’s littermate, alpha and captain. We lost him due to hemorrhage and dehydration. He just recently turned 4 months. Apollo hasn’t been eating and drinking water today. Was asleep all the time, too. Previously, he wakes up at night and cries so he comes to me in bed to wake me up. Last night he started vomiting and having loose stools. I can also here rumbling in his stomach, and i think is passing gas. Earlier that day we went on a walk and had munched a few plants/weeds on the way. He has also accidentally taken in expired milk he left the other day. Today the stool had a few blood patches in it. I’m worried he might end up his brother. Is he only suffering from dog depression, or is there other medial conditions?
