You can search online for the nearest veterinary ER and take Toby there if you are concerned about an acute toxicity, injury or illness. If no clinic is available, keep Toby as comfortable as you can. Do not offer any food if he is vomiting and do not give any medications. Have home seen by your veterinarian first thing in the morning. Without knowing what is wrong, it is difficult to determine care. The emergency clinic would be the safest option in this case.

    Unfortunately it is hard to say if your pet is stable right now without the proper physical examination, so that makes it difficult to say if Toby will be ok through the night. Sometimes vomiting and lethargy can indicate that your pet has a really bad GI upset and other times it can indicate another disease process altogether that just happens to have the same symptoms as an upset stomach. So the best thing to do is to look at Toby's gums, if they are pale this is an emergency. If he is having respiratory distress and not able to get enough oxygen, this is an emergency. If he is laying down and unresponsive, this is likely an emergency. Hopefully this is just a really bad stomach upset and getting him seen in the morning for proper care is recommended. The vet will need to do a thorough examination of Toby to determine the likely cause and then recommend medications (i.e. anti-vomit medicine, fluid therapy if he is dehydrated, and treating the underlying condition) to help him stabilize.
