Vets and veterinary oncologist use Doxorubicin (also called Adriamycin) in many different chemotherapy plans.
Common dog cancers treated with this drug include lymphosarcoma, hemangiosarcoma, other sarcomas, and carcinomas.
This is not a mickey-mouse drug. It is one of the main players in conventional dog cancer chemo treatments. It also has corresponding side effects that, from time to time, are heavy duty and should be taken into account.
Doxorubicin is given as an injection in the vein at the vet hospital. If the tip of the catheter used to deliver the drug is not in the vein (but still under the skin), the drug will end up in the tissues around the vein.
Doxorubicin is very toxic to living tissue when given in this way and will cause this tissue around the vein to die.
It can also cause stomach upset, inflammation of the colon, and delay the regrowth of hair. Some dogs will develop allergic reactions during doxorubicin injections. It can bone marrow suppression (anemia and low white blood cell and platelet counts).
It is known to cause damage to the muscle in the heart, in some dogs, which can be quite serious.

The reader should be advised that the purpose of this content is not to crucify doxorubicin. It has helped many dogs. Rather, this is information that should be in your head as an informed advocate of your dog’s health.
In the next post, I will discuss the use of common, over-the counter-supplements that should be considered to help alleviate a big toxicity with this drug: heart damage…
