Can trauma cause a dog's benign tumor to rupture and bleed internally?

Absolutely, you are correct in thinking that there could be an internal bleed causing these episodes of pale discoloration to the gums. An abdominal ultrasound and chest x-rays would be helpful right now to see what is going on internally. There could be a catastrophic event at home if a major blood vessel bursts or a large vessel bursts / ruptures on a tumor in the abdomen causing severe hemorrhage in the abdomen. If you notice the belly getting larger, there may be a slow bleed inside the abdomen. I would have Kayah rechecked as soon as possible so that you can get more information. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

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!

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. I am glad we can give you some assistance! I am not familiar with your previous questions regarding Sweetie but if the tumor is ulcerated, that is not typically a good sign. It sounds like tumor needs to be removed surgically. It is a bit difficult to advise you without seeing the tumor myself and I'm not 100% sure what your question is exactly. You want us to suggest something meaning what? To apply topically to the tumor? For bandaging? To stop the bleeding? I'm not exactly sure what you are looking for. If the tumor is ulcerated she is most likely going to need to get some antibiotics. It is also very difficult to give you advice if we don't know your location. It does no good for us to recommend products that you cannot obtain in your area. Please post again with more information. Thank you.

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.

This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Differentials include skin cysts, infections, benign or more sinister type of tumors. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hi we cannot see previous questions that you have posted on Petco Pet Education Center, formerly Petcoach. If you have a more complex case feel free to set up a consultation with myself or one of the other experts. But I'll do my best to answer the question do you have here. There are some tumors or cancerous masses that may appear to decrease and increase in size such as mast cell tumors or histiocytomas that may spontaneously regress on their own but can recur in other places. Certain medications can also cause tumors to shrink in size but they may regrow ones that medication is not as effective. Depending on the type of cancer and what organ system in the body it is affecting, many dogs live seemingly normal happy lives up until the point they can no longer compensate or the cancer spreads. For many different reasons owners do not always choose to pursue cancer treatment or in some cases it's not possible. But the pet can still live months to years relatively happy. I hope that was some help, if you have further questions feel free to open up a consultation. Thank you for using Petco Pet Education Center, formerly Petcoach.

Thank you for submitting your question regarding your dog. I would recommend that he/she sees a veterinarian to rule any serious injuries from being hit by the motorcycle. It could be a swelling from a collection of fluid under the skin known as a seroma. This can happen when tissues are bruised and inflamed such as secondary to trauma. In this case, the swelling should not be painful to the dog and resolve given time. A more serious consideration would be if there is a tear in the abdominal wall. In this case, the internal organs can migrate under the skin. This can be life threatening. Finally, your dog could have a mass that has occurred coincidentally around the time of the crash, but is unrelated. A fatty tumor called a lipoma is a common growth under the skin. Your veterinarian will be able to differentiate between these scenarios and recommend any necessary treatment. I hope this information helps!
