My puppy's breast lump popped after birth. What does it mean?

Unfortunately, even in person I would be hard pressed to give you a diagnosis based only on appearance. When a client comes in with a pet that has an unknown mass, we typically consider the following as possibilities, taking many factors into account: a mass/tumor, an abscess, a cystic structure, an insect bite, an allergic reaction, or a bruise from trauma. If the structure has burst open, it is most likely not allergic or from an insect. Depending upon your dog's age, the time the lump has existed, the consistency of the fluid you have noted, and the presence / absence of any other clinical signs, one of the other options is most likely. Something the vet might be able to do is obtain some cellular material from the affected area, place it under a microscope, and see if there is any cellular material that is useful in obtaining a diagnosis. Other times, appearance alone can at least tell a vet whether or not there is an active infection. As far as the possibility of cancer, tumors are certainly able to open up as you have described. They are typically more common in elderly dogs, though even this is largely dependent on the type of tumor. I would schedule a visit with your vet sometime soon. I would also in the meantime prevent Pancakes from bothering with the area. You can either buy an e-collar from a store / vet, or try and make something homemade until a commercial one can be obtained (with it being Easter, finding a store open that has one may prove difficult). The purpose of this is to prevent any current infection from worsening, or absent infection from beginning. Hope this makes sense.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. It sounds like this wound that became a lump that is oozing fluid has become an abscess, or a pocket of infected fluid. Abscesses form when infection is trapped under the skin or within tissues such as fat or muscle. The bacteria will try to find a way out, so they can break through the skin and create a "draining tract" of pus. This should be addressed by your veterinarian, who will likely drain the abscess and open it up to allow continuous drainage. Antibiotics for at least 2 weeks will be needed, along with pain medications. Depending on the size of the wound/abscess, a bandage may be needed. I hope this is helpful! Thank you for seeking care for your Luna!

This looks like it could be a cyst or a skin tumor like a hemangioma. I find that once a skin growth ruptures it tends to happen again, so I would definitely recommend making an appointment to see your veterinarian. They will probably recommend surgically removing this growth.

It is very hard to say what the lump is without examining your dog and possibly taking a sample of the lump for pathology. It is possible that the lump is a mammary gland tumour (benign or malignant) but it really does not often happen in such young dogs. All you need to do at the moment is to keep the wound clean and make sure that Aubrey does not lick it. Once your vet is open, you need to take your dog for an appointment.

There could be a few things that look like that. An infection that ruptured through the skin, a bite wound, a fly larva or a cyst that popped could all have this appearance. I would recommend to take Pepper into the vet within the next 24 hours to have an exam and likely antibiotics. Make sure to protect the area from Pepper licking it or scratching it as this will make it worse. Also make sure to clip the hair short and wash it with an antibacterial soap! I hope this helps!

Oh no, poor Pebbles! It's certainly possible she has an abscess, but if she is intact (not spayed), then it could be a mammary tumor. Poor girl that it's painful! Because it's painful, it's best that she is seen by a vet first thing in the morning. The vet can diagnose what is causing this lump, and then can discuss treatment otiose with you. If it is an abscess, it will need to be drained and flushed sterilely, and she will need antibiotics for the infection. Should it be a mammary tumor, then there's a 50% chance it's malignant. Depending on if it has spread or not, removing it surgically may be curative.

Hi there and thanks for posting! If you cat has a lump or mass that has appeared to have ruptured, I would visit your veterinarian right away. The mass may need to be removed or treated with antibiotics. Your veterinarian may also take a sample of the mass to determine what it is and if it needs to be removed. I hope this helps and thanks for using Petco Pet Education Center, formerly Petcoach!
