Hello, I just answered your first question about Monty! I would recommend to finish the antibiotics first as they may cause him to have an upset stomach. That way its not so many things at once on Monty's little tummy.
Make sure to give all the medications with food. It should be fine for you to give both the Doxy and Metro at the same time. If his stomach does get upset, call his veterinarian as the doctor may want to stop the medications.
I hope this helps! Please post again if you have any further questions.
