GS not eating...

Question
I have a 19 month old German Shepherd that I adopted about a month ago. He is a rather large dog for his breed. He is very tall with long legs. Over the weekend I took him to a trail and he went swimming in a creek. The next day I took him downtown for a day full of walking and interaction with lots of people and other dogs. When we got home everthing was fine. He ate well and laid down and went to sleep. On Monday morning he ate fine as well. Monday at noon he was playful and go-lucky. When I arrived hom from work Monday evening he would not eat and was very lethargic. It's now Tuesday morning and he still wont eat his food. This is very unnatural for him as he usually can't wait to eat. Also worth noting is that the temperature was significantly higher than normal over the weekend and on Monday. I am worried about him not eating. What should I do?

Answer
Hi Victor,  I am sorry I couldn't get to your question sooner, we had a family emergency this week so I fell behind in questions.  I hope that you got him to a vet if he continued to get worse.  If you need anything else, feel free to let me know.
