I woke up to my dog crying last night, he had a sore on his rear end and there was blood and pus all over. This was not there a few hours before; it was like a horror movie. Now he has a sore, somewhat deep and keeps licking it. I cleaned it but might need antibiotics? Could it be an insect bite?

Based on the location (it appears to be just to the side and just below the anus), an anal gland abscess may have ruptured. I doubt it’s an insect bite, but I can’t rule that out completely. It could also be another type of mass such as a tumor or a foreign body (such as a grass seed) that’s burrowed into the skin and caused an abscess. Regardless, your instincts are correct; this likely needs to be treated with antibiotics. Put an E -collar (cone of shame) on him and make an appointment with your vet ASAP. Hope that’s helpful!
