Sardines for Dogs and Cats – Whole Food for Good Health

Sardines for dogs and cats – an excellent whole food to maintain good health and an excellent treat. Fresh-frozen, whole sardines (head, body, tail) are the preferred choice for ultimate nutritive value.

Canned sardines are cooked at high temperatures resulting in loss of nutritional benefits, and toxic contamination. Toxins in the can, including BPA in the lining leach into the food. Studies have shown that even short-term feeding of canned products increases the concentration of toxins in a dog (or cats) body. For these reasons raw-frozen sardines are preferred over canned, however if you select a canned sardine product with care, even canned sardines can improve a diet of dry highly processed pet food. If you must use canned sardines, avoid products that contain inorganic table salt / iodized salt. Avoid products that contain toxic oils such as (non-organic) unspecified ‘vegetable’ oil, canola oil, soybean oil, safflower oil, or cotton seed oil – these are all GMO oils contaminated with glyphosate (a carcinogen).

Most grocery stores sell uncooked, whole fresh-frozen wild-caught sardines. You can also purchase fresh sardines. Sardines have very soft bones dogs and cats can consume without fear of harm. The bones are an excellent source of calcium. No need to remove the head or tail of the sardine – nutritional value is increased when the fish is eaten in its entirety. There are two basic sizes of sardines – very small sardines, and larger sardines. Small sardines are a great treat. You can also choose to puree or finely grind sardines in a food processor or grinder to make your own fish pate for fussy kitties. The larger sardines can be sliced up in small pieces if you are feeding a small puppy or small-breed dog, or left whole for larger dogs.

Sardines are an excellent source of natural, unprocessed:

  • Antioxidants.
  • Essential macro-nutrients, and micro nutrients.
  • Essential Amino acids
  • Omega-3 fatty acids.
  • Rich in protein.

Sardines can help your Dogs and Cats:

  • Bone health
  • Brain health
  • Cardiovascular health
  • Eye health
  • Joint health
  • Metabolic health
  • Mental health
  • Skin health
  • And more!

Dry / Canned Pet Food, Cooked Food Diet Dogs and Cats

If your dog and cat is currently a diet of highly processed dry food, canned food, or home cooked food you have two choices –

  • You can lightly (at the lowest heat setting), cook the sardines in a little healthy oil – i.e. organic coconut oil, or olive oil.
  • You can also choose to introduce your dog and cat to raw sardines.

Raw Fed Dogs and Cats

If your dog and cat is currently on a raw diet, you can introduce raw sardines – simply thaw and serve.

Introducing Raw

  • Start by offering one raw, frozen-thawed, small piece of sardine (or small whole sardine) away from meals (in between meals).
  • If no adverse reaction occurs (i.e. loose stools, diarrhea, vomiting), you can repeat the treat again the following day.
  • You can slowly increase the size of the treat – i.e. a medium size dog – start out with a small piece of sardine, and slowly build-up the amount given over the space of at least several weeks.
  • By following this process you can avoid adverse reactions that occur when raw food is introduced too quickly, and in too large amounts.


  • If your dog has a food sensitivity to other fish, he / she may also have a sensitivity to sardines.
  • If trying raw for the first time, and – you have carefully followed the instructions above, and an adverse reaction occurs your dog (cat) may have a food sensitivity to sardines – stop use.

Fresh-frozen sardines are an inexpensive, simple, convenient, healthy whole food treat for dogs and cats.  For more information about options and safely adding fish to your dogs and cats diet go here.

  1. Hi Karen
    Thank you for the information on this site… I have a 16 year old cat and I used to feed him for breakfast canned sardines in spring water and he loved them… But the vet said not to feed him this anymore after he had a bout of urinary issues (couldn’t urinate and had to have a catheter ) I took him off all dried food and he now eats raw organic meat (kangaroo, with bones and organs in the mix) I have not looked for frozen sardines but would he be able to have these or would this create the urinary problems again?

    • Hi Sandra, I don’t recommend daily use of CANNED food, including sardines as toxins from the metal and can lining do leach into the food. In order to advise you in a meaningful way regarding whether frozen sardines are good for your kitty, I would need to look at his background information.

  2. Hi Karen, Thanks for all your amazing blog posts! I bought some fresh larger sardines and my dog (70lbs) eats homemade cooked food.

    Are you saying I can cook those sardines whole, bones and all, and put them in his food?

    I’ve always been scared of all fish bones.

    Thank you so much!

    Hello Karen

    My name is Wayne Mattingly and I live in Stittsville On 613-599-3364

    We have a 5 month old Mini Schnauzer named Oscar and as for the terrier in him , he has a barking problem… a bad one actually.

    We don’t want to take away his desire to protect but we would like to walk him and not having him barking at everyone or everything.

    He has been to puppy class but becomes so excited and beside himself when he sees other dogs he does not listen to commands etc. I know he is very young but we want to nip this problem now and not let it continue to get worse.

    Do you think you would be able to do anything with Oscar to help him relax a little

    I have just pulled him out of his 2 nd puppy class because he is out of control

    I am sure you have all of this before. If you could contact me either way that would be great.

    Thanks Karen
