My dog was bitten and has a red lump. What is it and what can I do?

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.

I'm concerned this is an abscess. A dog's mouth has a lot of bacteria and Diamond was bitten by the other dog, it can cause an abscess. This cannot be treated at home. You need to have her seen by a vet today. It needs to be drained in a sterile manner, and she needs antibiotics and pain medication. I hope this helps!

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.

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!

Thanks for using Petco Pet Education Center, formerly Petcoach! This lump you describe could potentially be something like an abscess for example. However, other things are possible. If there is really an abscess, this should not be treated at home. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. If an abscess was noted, further local therapy with drainage and antibiotics would be recommended. Good luck and best wishes!

It's probably an infection that is spreading due to the bite, you must take her to the vet ASAP, the vet will drain the fluids that accumulated under the skin and prescribe antibiotics to fight the infection.

I see what you mean about the lump, it is quite big and red. Bruce is a young dog, so the chances of it being malignant are not high at all. I would be wondering if it is from an insect bite, a cyst, or potentially a foreign body in it like a grass seed. I do think it's a good idea to get checked out by a vet tomorrow, but I would not have a digital tumor high on my list as a potential diagnosis. I hope this helps!
