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

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

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.

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 area to help prevent infection by making sure he wears the “cone” (also known as an e-collar or Elizabethan collar) at all times when he is not being directly supervised by you, including while sleeping. Pain medications meant for humans can be very dangerous (and even deadly) for dogs, so I do not recommend giving any to your pup without consulting with your vet. Your veterinarian can prescribe safe medication to help with the pain as needed. Hope your pup feels better soon!

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.

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.

Oh no, poor Maddie! It's very concerning that blood is coming out of her nipple and she should have suffering an injury or infection causing the lump and the blood. I would have her seen by a vet for this as soon as possible. The vet can diagnose what is causing her symptoms so she can be treated.

Many mammary tumours shrink temporarily after antibiotics as they often become infected in the centre, intact bitches can also develop mastitis which responds to antibiotics also. I would be concerned the bloodied discharge could be related to a womb infection and would recommend an ultrasound to rule this out. Bleeding around the eye is a warning flag for lymphoma but can occur secondary to many inflammatory conditions, referral to an ophthalmologist would be worthwhile in order to explore all avenues
