    Why I no longer recommend sardines for dogs

    Can dogs eat sardines? 7 steps to protect your dog from radioactive strontium

    Over the past several years, I have seen an increased number of dogs with severely elevated levels of the element strontium upon reviewing their HairQ test results.

    Generally, we collect the nutritional history of every dog who's sample was submitted for a HairQ test. What we discovered is that dogs whose hair contains high levels of strontium eat higher amounts of sardines or sardine based omega oil supplement.

    Strontium acts the same way as calcium in the body and deposits in bones. There are several stable (non-radioactive) isotopes, Sr 84, 86, 87, and 88, which are the fifteenth most common elements in the Earth's crust.

    The strontium that is a concern is the radioactive isotope Sr 90, which was released in large amounts from the Fukushima disaster site in Japan.

    The reason I am concerned 

    We are seeing increased levels of strontium in dogs that eat sardines or sardine oils.

    Japan is one of the largest exporters of sardines in the world, and, unfortunately, the primary spawning area of Japanese sardines is near Fukushima.

    Japanese sardines are purchased frozen by canneries around the world, and these canneries do not have an obligation to mark the country of origin. These oils are used in fish oil supplements for dogs, and some dog food.

    Strontium 90's properties are similar to calcium, and it deposits in the bones of contaminated fish. Most fish are not eaten or processed with bones except sardines and small fish. 

    The bones are small and soft and no matter if your dog gets sardine oil or if he eats sardines right from the can, strontium may contaminate your dog’s body.

    I am not saying that every can of sardines is contaminated. It is just near to impossible to know the origin of sardines and other small fish you purchase and the same applies to fish oils for dogs.

    The following results are an example of strontium contamination in a dog's body:

    7 steps to protect your dog from radioactive strontium
    1. Stop feeding sardines or other small fish that is traditionally eaten with bones.
    2. If you have been feeding your dog sardines or any fish oil, use the HairQ test to determine what your dog's levels of strontium and mercury are.
    3. Replace your dog's fish oil with calamari-based Omega-3 oil such as FeelGood Omega, that is tested mercury free and is not processed with bones. 
    4. Take your dog through a general liver cleanse program for two months.
    5. Start a plant-based mineral and calcium super food, GreenMin. Supplementing your dog’s diet with calcium will help to push the competing strontium out of the body.
    6. If your dog’s first HairQ test results show elevated strontium and mercury levels, do not panic. Just go through steps 1-6.
    7. Repeat the HairQ test in 6 months. It is very likely that you will see your dog’s strontium levels drop.
