Blood in poo -
2 year old rescue springer spaniel, had sore place on leg that he'd been licking at and saw vet yesterday who gave cephaexin 275mg twice daily and prednisone 5mg once daily. He's just done a poo with red blood on top /little mixed in. My son said there might have been a bit of blood in the poo this morning. He seems fine in himself, big walk, good appetite. Any thoughts?? Do I need emergency vet or can it wait until mine opens tomorrow 8am? I'm worried
