Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Hercules. If he was tied up, he could have been pulling against the rope, leading to that red mark. Now it could also be from something else like a rash, and if he's whining, that could mean he is in pain. I think it's best you have him checked out by a vet, and I would take him into one this weekend. I hope this helps!
