My dog's antibiotic turned yellow and crumbly. Will he be okay?

Hello, just then I gave Jack his last half-tablet of antibiotics (Amoxyclav 200mg) with some food as usual. However, the half-tablet looked light yellow and it crushed into powder easily. It was a second half of a tablet which I stored back in its foil and then in the box and kept it overnight to take out again this morning. I did the same with the other tablets but they were all a normal white colour. I gave the yellow half-tablet to Jack anyway as I assumed it was the moisture. Will he be ok?

If you are sure it was the Amoxyclav then it may have drawn some moisture. He will probably be ok. Should he show signs of discomfort or vomiting, then you might want to take him to your vet for an exam.
