Omega-3 Fatty Acids

According to Jennifer Coates at petMD, dogs cannot make their own omega-3 fatty acids. This is why dogs have a dietary need for omega-3 fatty acids like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

Mussels are an expensive source of omega-3 fatty acids to meet the requirement of a dog. It contains eicosapentaenoic acid (EPA), eicosatetraenoic acid (ETA), and docosahexaenoic acid (DHA) which are omega-3 fatty acids.

It can support various functions in a dog’s body:

  • reduces inflammation in the joints(helps with conditions like arthritis)
  • supports brain development and keeps cognitive function healthy
  • promotes supple skin and glossy coat
  • supports both kidney and heart health
  • boosts the immune system

High Protein

Protein is part of a dog’s daily diet and mussels contain 24g protein per 100g serving, with all the essential amino acids. Their protein content is superior to that found in fish with fins. The protein in mussels is easy to digest, so the dog will get the full benefit of it.

Various ways in which protein in mussels can benefit the dog are:

  • builds and repairs muscles
  • provides energy
  • forms new cells
  • promotes hair growth
  • keeps immune system strong
  • creates essential body chemicals

Various Minerals

Mussels are a good source of minerals such as iron, magnesium, and zinc, which support overall health and well-being. So, having your pet get the vitamins and minerals from mussels is generally a better health plan than relying upon synthetic vitamins added to meals and treats.

  • Iron: provides oxygen to organs, promotes energy production in cells and strengthens the immune system
  • Magnesium: maintains bone and cartilage in the joints
  • Zinc: boosts the immune system and the quality of skin and fur

Low in Fat and Calories

Mussels are low in fat and calories which makes them a perfect treat for dogs who are overweight or trying to manage their weight. Along with that, low calories will also ensure stable energy levels throughout the day.

The omega-3 fatty acids, protein, and minerals found in mussels can also be found in other shellfish like cockles. So you may be wondering, can dogs have cockles?

How Many Mussels to Feed a Dog?

Though mussels are nutritious, they shouldn’t be consumed by the dog in large quantities. It will only benefit the dog if consumed in moderation. The amount of intake depends on the size, weight and breed of the dog. As a guideline, no more than one or two ounces of mussel per 20 pounds of body weight, which means one to two whole mussels per 20-pound dog.

Mussels can be a healthy supplement to your dog’s diet but they shouldn’t make up more than 10% of your dog’s daily calorie intake. The remaining 90% of calories should come from their daily well-balanced diet.

For getting started with it, you should feed a small quantity(just one mussel) and wait for your dog’s signs of acceptance. However, if you are not sure about the amount to feed, you may consult a veterinarian and he/she can guide you effectively.

Moreover, you should avoid feeding raw mussels to your dog as it increases the risk of bacterial contamination.[2] Mussels should be cooked and prepared properly before feeding your Fido. You can steam, grill or bake the mussels. Also, make sure your dog does not shallow the shell as it can lead to a choking hazard for your pet.

While mussels provide great nutrition for dogs, other mild white fish like haddock are also good in moderation. If you’re wondering is haddock good for dogs, consider asking your vet before feeding them.
