Dog has a ruptured, bleeding lump. Is it a tumor? What should I do?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Female | unspayed | 1 year and 1 month old

It has been a week since our dog started to have a lump. I didn't dare to touch it because I was scared it might hurt. Days after, we noticed that it was ruptured. What could it be? Is there a possibility that she has tumor? This photo was taken yesterday. Today, another lump was ruptured and is bleeding. I am worried that she might end up dying. Due to enhanced community quarantine we can't take her to the vet. What should we do?

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.

    It's probably either an infection or a foreign body in the paw, you will need to have it looked at by your vet ASAP, he will probably need a course of antibiotics, if it doesn't help the wound will probably need to be inspected under sedation.

    Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

My german shephard had a pea sized lump on her side that burst. Just bled. No pus. Should i be worried? She is 10yrs old.
Yes, I would be worried because it's not normal for dogs to have bleeding lumps. It could be a cyst, but in a senior dog, there is always a concern that it's a malignant tumor. I would apply gentle pressure to the lump to try to stop the bleeding, and then have Raya seen by the vet in the morning. The vet can diagnose what is causing the lump, and can discuss treatment options with you. Keep her from licking at it overnight, and you may have to put an Ecollar on her to stop her from doing it. You can get one at a pet store, or can make one yourself: http://dogsaholic.com/care/homemade-dog-cone.html

Hey, my Staffordshire bull terrier is 5years old & has had a lump on his hsoulder since the age of 1, it has grown to be 2inches wide and half an inch in height and is a black/grey colour, its never harmes him but weve been too scared to bring him i
No, of course you will not get in trouble for not getting him seen two years ago. The fact that the lump is now growing to the point where the skin opens and it is bleeding does point to a tumor. Hopefully it can be easily removed. Your vet will give your dog a thorough exam and will take a tissue sample to be sent to a laboratory to dedtermine if the mass is malignant or benign. Since it is bleeding it will need to be removed in order to avoid infections. I am sure your vet will discuss all the options once he has determined what kind of mass it is. It is obviously a slow growing mass, or your dog would have had problems much earlier.

It could be an abscess, it could also be a tumor, you must take him to the vet in order to get that treated, the fur in that area must be clipped off completely, the wound needs to be cleaned and analysed. if it is an abscess a course of antibiotics will solve the problem.

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.

My dog Trey has a mole looking thing on his stomach and he keeps biting it. It bleeds when he bites it. It looks painful for him but I don't know what to do to help him. Please help! do you know what it might be and how I could help him?
Without further testing, there is no way to tell if this growth is due to infection, trauma or allergy, or if it is a tumour. Tumours can be of a malignant (cancerous) type that can spread elsewhere and/ or invade the healthy tissue around them, or a more benign (noncancerous) type that is unlikely to spread. I recommend making an appointment to see your vet to have the growth tested. In many cases this can be done using a fine needle aspirate, where cells are removed from the growth using a needle and examined under a microscope to determine what it is and to guide treatment. In some cases further testing may be needed to determine the necessary course of treatment, but it is important to get new growths tested in a timely manner, as some can be cancerous and quite aggressive in their growth, and growths due to infection, allergy or trauma can lead to complications or be indicators of underlying health problems. In the meantime, it is very important that you keep Trey from licking the

Hello and thank you for using Boop by Petco. This is a mass/ tumor that has broken open. It may be benign or cancerous and the only way to know which is to send it off for analysis. This growth should be surgically removed as it runs the risk of being a chronic source of infection since it has ruptured. Your veterinarian can send it off for analysis once it is removed. Thank you

My dog had a gumball size lump on his leg, a week later he started licking it (today) anf i looked, & it was hollowed out and it was bloody and pussy and deep.
This can be one of two things: 1) a small abscess that has ruptured. 2) a small tumor that did not have enough room to grow and therefore started to ulcerate and finally ruptured. Since it is on a leg and deep, you should have your veterinarian have a look at it, to see whether any vital structures are involved and whether it is a tumor that needs to be removed.

Angel having memory gland tumor (lump in one of her nipples). Vet advised operation on 23rd but today I found tumor ruptured and gaping hole. I have cleaned the would with betadine but vet not available till 16th. Please advice precautions I need to
This definitely cannot wait until the 23rd but she could probably wait until the 16th if your vet is doing the surgery that day. until then it's mainly a case of keeping the ulcerated tumor clean as much as possible, if necessary it is possible to bandage the area as well with special dressing. if it is bleeding profusely you will need to take her to an emergency center today.
