In addition to the micronutrients mentioned above (minerals, trace elements, and vitamins), fish also contains essential macronutrients such as proteins and fats.

Fatty fish species, such as herring, salmon, or mackerel, contain the omega-3 fatty acids essential for dogs. The body of dogs cannot produce them itself, which is why they must be absorbed through food.

Good to know: Unlike humans, dogs can produce omega-6 fatty acids. Unlike omega-3 fatty acids, these do not have to be consumed with food.

Omega-3 fatty acids support the health of your dog’s fur and skin and also act as natural antioxidants. Docosahexaenoic acid (DHA) also contributes to the healthy development of the brain and nervous system.

These polyunsaturated fatty acids strengthen the immune system and protect your dog from inflammation and cardiovascular diseases.

Fish is also an important source of protein. Protein (protein) is an essential nutrient for dogs, which is needed for various metabolic processes. Protein is vital for the health and growth of muscles, bones, organs, skin, and fur.

In what quantities can I give fish to my dog?

You can give your dog fish several times a week as an alternative to meat. Fish is an excellent alternative, especially for dogs with sensitive stomachs and do not tolerate animal proteins from poultry or cattle.

Tip: Make sure that the main ingredient of the treats is fish, and cereals and sugar should not be on the list of ingredients.

In addition to various choices of wet and dry food containing fish, there are fish-based treats for your four-legged friend. You can give this to your dog without hesitation (of course, in moderation, just like all other treats) daily.

It is essential to pay attention when feeding fish

Herringbone is elastic and soft and can be devoured in the raw state. For this reason, even wild animals such as wolves can tolerate fish well.

When fish is cooked or fried, the contained bones can become very hard and pointed and easily splintered. It can lead to injuries in the mouth and neck, and other internal organs. Therefore, you should ensure that you have removed all bones before giving them to your dog for consumption.

Caution: Remove all bones of cooked/fried fish, so your dog does not get hurt when eating.

  • Bream
  • Butterfish
  • Hering
  • Carp
  • Maisch
  • Lamprey
  • Anchovy
  • Stint
  • Zander

When feeding thiaminase-containing fish, you should make sure that you serve it only in small quantities. Another option would be to supplement the fish with vitamin B1 supplements, such as vitamin B1 or vitamin B1.

More tips for feeding fish

  • You can mix the fish with rice or potatoes if you prepare the food. So it is also suitable for dogs with a sensitive stomachs.
  • If you want to give your dog raw fish, make sure it’s fresh. For example, you can recognize fresh fish by the smell, which must not be unpleasant, the meat must be firm, and the eyes must be crystal clear.
