Poor Blu! He's a cute dog but looks like he doesn't feel well. I am very concerned that he hasn't eaten all week. That is definitely abnormal and at this point could be experiencing severe dehydration and even low blood sugar from lack of nutrition. This change in behavior could be do to a long list of problems, such as intestinal parasites, viral infections, pancreatitis, gastroenteritis, or even a congenital problem, since Blu is so young. I would recommend you take Blu in to your vet as soon as possible to be evaluated and potentially have some tests done. At minimum he likely needs some supportive care, like fluid therapy and anti-nausea medication to get him eating again. I hope Blu is on the mend soon!
