I am very sorry to hear that Max is experiencing these problems, I am sure it is very unsettling for you both. There are a number of potentiall causes of such clinical signs, including dietary indiscretion, pancreatitis, parasite infestation, infection, and ingestion of a toxin or poison.

Because you have only noticed these signs over the course of a few hours I would continue to monitor Max at home. The foamy clear vomit you noticed is most likely the final contents of Max's now empty stomach; bike and stomach acids. It's not anything to be worried about. .

Rest Max's gastrointestinal tract by holding back food for 12 hours. Then you can continue with a bland and easily digested food of the boiled chicken breast and white rice diet and provide plenty of fresh water.

If Max does not improve, has sever vomiting or diarrhoea, you notice fresh blood, Max seems lethargic, in pain or depressed I would advise a trip to the veterinarian.

I hope that answer was helpful and more importantly that Max feels better soon. Warmest regards to you both.
