What is this firm, draining bump on my dog's paw and what should I do?

Hi, I have a 4yo male GSD that has a cyst-looking bump just above his rear right metacarpal pad. I noticed it a few days ago when it drained after a play session. Since then I've kept an eye on it and it has become firmer and two pores appear to have darken. Thoughts?

I can’t tell exactly what this is with the picture alone but a draining wound on the foot warrants an examination by a veterinarian. It could be an infection/abscess and the location (being so close to the ground) can cause the wound to become dirty and soiled, making the infection worse. Or, there could be a mass present and if this is the case, it would need to be removed as soon as possible. In the meantime, until you can get to your vet, keep the area clean and dry and try to prevent Rex from licking the area. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
