Q. My dog ate grass, vomited fluid and then coughed up what looked like a T-shirt and re-swallowed it. Can I give him something to throw up or what?

A. My personal advice would be to take him to your veterinarian as soon as possible to have him checked and make him sick (apomorphine will make him sick instantly).
Otherwise you could try with some hydrogen peroxide following these instructions.
Measure 1 milliliter (ml) of 3% hydrogen peroxide per pound of dog weight, using either the syringe or teaspoon. One teaspoon is approximately five ml. The maximum amount of hydrogen peroxide to be given at any one time is 45 ml, even if a dog weighs over 45 pounds. Squirt the hydrogen peroxide into the back of the dogâ€™s mouth using the syringe. If vomiting has not occurred within 15 minutes, give one more dose of hydrogen peroxide measured out as described above.
If vomiting still does not occur, call your veterinarian.
