What do you do when your dog has diarrhea and/or vomiting? If it persits for more than a day, the dog has a good chance of getting dehydrated. Since that can lead to more severe medical issues, you need to bring him to a vet.
In Alvin's case, the vet checked him for dehydration, gave him a shot to stop the vomiting, and presecribed a special dog food.
He recovered in about 2 days. In the meantime, Simon started with a much more severe case of vomiting and diarrhea.
Another trip to the vet - same treatment with the addition of bloodwork, an antibiotic shot, and an entire day of fasting! Simon fasting? Okay, so he's a little overweight. But Simon not eating is a very unhappy canine. As I write this he is moaning because he had a few spoonfuls of the special dog food and thinks my lunch belongs to him. What a sad face!

Today, Alvin is fully recovered and Simon is on the road to recovery. The blood work showed no pancreatitis (a very good thing)!
