Is dog cancer contagious? My dog was near a dog with cancer.

Thanks for using Petco Pet Education Center, formerly Petcoach. I'm so sorry to hear about Brandy. Lymphoma is not in any way contagious and would be no risk to your maltipoo. However, if we're not sure about the diagnosis, I will just say that there are a couple (uncommon) infectious diseases that can cause large lymph nodes. And these diseases CAN be contagious sometimes. Talk to your vet if you have concerns but my guess is that your maltipoo will be perfectly safe interacting with Brandy. Best wishes to you all.

Stomach cancer may have a genetic compound, or could just be bad luck. Cancer is when cells start to multiply excessively, but do not, like normal cells, die off when they have reached a specific age, So they just keep growing. Cancer, with the exception of very very few, is not contagious. Stomach cancer is not contagious.

Heartworm disease is contagious but has to go through a mosquito and cannot be transmitted from dog to dog directly. Tracheal disease, a hernia, allergic airway disease and for the most part heart disease are not contagious. Fungal disease can be contagious in some situations. Hope this helps!

I'm very sorry Matte possibly have TVT! The good news is that is isn't contagious to humans, so you don't have to worry about it spreading to you or anyone else. This type of tumor rarely spreads to other parts of the body, so that's another piece of good news for you. In some dogs, these tumors can spontaneously regress, but it would be best to have it removed. Having it removed may be all that's needed to do to cure Matte of it, so I would speak to your vet about having the lump excised. Given that there is no pathologist who can handle the lump for diagnosis, I think your best bet is to remove the lump completely and see how he goes. I hope this helps you and Matte!

Thanks for using Petco Pet Education Center, formerly Petcoach! Overall, from what I'm reading and seeing, I have a low level of concern about Mukwa. This lesion does not look typical of a mast cell tumor (though that type of cancer does not always follow the "rules"). In general, non-cancerous things do not become cancerous with time - though there are exceptions. Occasional vomiting is not necessarily something I equate with Mast Cell Tumors, but does warrant a chat with your vet to see if it's something worth looking into. More concerning signs to me would be decreased appetite, weight loss, or lethargy. Best of luck to you and Mukwa!

I'm so sorry to hear about you losing Shadow. There are breeds that are more prone to cancerous/malignant tumors, however there is no dog, unfortunately, that is immune to cancer. Cancer in animals, just like with people does not really have any rhyme or reason to it. In very general terms, larger breed dogs, such as Golden Retrievers are more prone to cancerous tumors. I wish there was a way that no animal or person got cancer. Hope this helps answer your question. Take care.

Non-ractive warts and other growths which do not cause the dog to chew on them are usually not of concern provided they do not grow, or grow very slowly and are not oozing a discharge, bleeding or causing infection. That said, every growth should be examined by a veterinarian, as it could indeed be malignant. Previously benign masses can also turn into malignant masses. As for cancer cells spreading in the body from being ingested: that would depend on the cancer. If the mass is cancerous and just in the skin, it is likely that removing it with a good margin (healthy tissue surrounding it) may be curative. Your veterinarian will have to examine the mass and palpate it and may want to remove it right away, or do a fine needle aspirate to determine whether it is indeed a cancer. Since it is bothering your dog and Nisha is chewing it , there is a chance that it could get infected, another reason to have it examined ASAP.
