Amoxicillin is fine to give with dairy products.

Just make sure that both the Amoxi and the Aspirin is given with food and not on an empty stomach. Doesn't need to be much food, it's just sometimes tummy's get upset on those if it's empty.

I sure hope this week passes quickly for you and Mrs. Magoo, and hopefully she'll stop rubbing soon and the tests will come back with no cancer!

Best wishes for you.
