What Is The Best Supplement for Dog Cancer?

Updated: February 22nd, 2019

We are faced with some hard choices when in a war against dog cancer.  The truth is, as dog lovers,  often we feel pretty undergunned and overwhelmed, with choices that range from not-so-great to downright awful.

One of the difficulties many have is the choice among the supplements discussed in this blog or in The Dog Cancer Survival Guide.  In the Guide I write about a rotating plan, using the main supplements for a period of about 2 weeks or so and then rotating to new ones.

Why is this?

The answer lies in the information we have available, or lack thereof.

As it turns out, actual studies yielding  information comparing the effects of a given supplement with the effects of another supplement simply do not exist.  We are not talking about test tube studies here, everybody.  Test-tube studies are all over the place and can be meaningless when used in living animals.

I am referring to a comparison, in living bodies, preferably dogs, between EGCG and curcumin, as an example.  Or Artemisinin versus Neoplasine. And so on.

The data simply is not yet available to us!

So what do we do?  The answer is this:  we rotate between them.  In this way we are able to average out the effects so we get an overall benefit that was greater than if nothing was used.  Say Luteolin works really well for a given dog’s T-cell lymphoma, but in another dog with hemangiosarcoma it does not work that well.  Or it works well in early lymphoma but not in late lymphoma.

Since we just don’t know, but we can gather evidence that it has worked in lab animals, test tubes, and in my personal research in some dogs, well, let’s use it!  But can we bank on it for all dogs with all cancers at all stages? No, we cannot.

Thus, use a couple of your big guns, for 2 weeks or so, and rotate to new ones.  You can keep the leftover pills for the next rotation!

    Hi Dr. Dressler,

    My 13 yr old Shi Tzu had just found sufferring in diabetes and a big tumor (or lump) right below the heart, near lung. Dr has not determine what it is but probably cancer. As he is at old age, has 3-5 level heart attack and bladder stone before, we decided not take him to do the operation. What supplement can we treat him to reduce the tumor(or lump) and probabilty of cancer?
    Best regard,

      Dear CC,
      I would spend some time learning about the Dog Cancer Diet, beta glucans (K-9 immunity), apocaps, artemisinin, omega-3’s, and the other approaches discussed in this blog and the Guide. You can use the search bar on the right side of this page, and for more complete discussions get the Guide, which is easy reading.
      I send you best luck
      Dr D
