This is Casey's worried momma. Casey pooped an entire puddle of blood on our morning walk. He's at the vet right now to be monitored and have some tests run. Please send some power of the paw his way, I'm worried sick!!
Update: I just heard from the vet, and it's looking like it's just colitis! That's an inflammation of the lower GI tract, often caused by stress or some viruses. She's starting him on some medications, and I'm going to take him home at lunch. Thank you!!
