My dog has a lump that's spreading after a dog bite. What is it?

Poor Scarlet! Bites can frequently lead to abscesses, which are pockets of infection. It might be that the stuff you saw draining was pus, indicating infection. She needs to see a vet for this, as antibiotics are needed to treat any infection. The vet can flush the wound out as well. I would take her into a vet first thing in the morning.

It could be that Tank has an abscess. This commonly occur after animal bites and are very painful to the dog. He does need to see a vet tomorrow, as if he does have an abscess, it will need to be drained and flushed, and he will need antibiotics to treat it. I hope this helps!

This large lump looks very infected, you need to take him to the vet ASAP in order to get it checked and treated, if this is just an infection a course of antibiotics will be needed but it could be something worse than that.

This is likely to be due to a fungal or bacterial infection. An immediate check up at your local vets would be necessary, combined with some skin testing (like hair plugs and culture) to confirm these suspicions.

It sounds like Cujo has developed an abscess from this bite, and he needs veterinary attention now for it. The abscess needs to be drained and flushed sterilely, and he will need antibiotics to treat the infection. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

Thanks for using Petco Pet Education Center, formerly Petcoach! Anytime a dog is bitten by another dog, especially a bigger dog, prompt evaluation is crucial. I recommend that you have Brownie evaluated by a veterinarian as soon as possible for further assessment and treatment. Usually what you see from the outside is just the tip of the iceberg and more internal wounds are possible. Good luck! I hope she recovers quickly!

The fact that it is swollen with a yellow bump has me concerned that it is becoming infected. You could clean the area with a wound wash but he really should be examined and treated by a vet as he may need an antibiotic.
