Poor Loki-boki seems sick. We took him to the vet this morning. The cause could be either a viral-type of cold or there could be a foreign object (like a blade of grass) stuck up his nose. In either case, we're just supposed to monitor him over the next few days. If it's a viral-type of cold, then we'll just have to let his body deal with it. Just like in humans, a viral infection cannot be treated with antibiotics. If it's a foreign object, which could have occurred during our recent hikes, then we'll have to return to the vet to have the object removed.
