Do you think your dog can be fed mackerel? Could you tell me how to prepare it and what provisos to watch out for?

What do you think? Lets find out.

1. Can a dog eat mackerel?

The answer is yes!

In other words if the fish are packed in water not brine.

Also whether it is cooked.

Fish contain some enzymes that can mess with your pups digestive system – more on that later. As it turns out dogs love fish – the smellier the better.

Making your dog some fish popsicles or mackerel fudge would be nice.

Puppies have different tastes from their human parents so it sounds gross.

Besides they lick their own butts and roll around in all sorts of smelly things. As humans we do not do that.

2. What is the nutritional value of mackerel?

There are plenty of omega 3 fatty acids in Mackerel which are crucial for your pups health especially healthy skin and hair.

Additionally it contains EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Using this stuff will enable your pup to play all day long.

In addition to fighting inflammation they boost your pups brain function both of which are essential for sustained healthy life.

Two or three times a week adding this to your pups meals will give him a much-needed boost.

Moderation is the key. There is such a thing as too much of a good thing.

3. What are the dangers of feeding mackerel to your dog?

These large predatory fish are known as Mackerel. There is a high concentration of mercury in their bodies and they catch and eat other fish that contain mercury. This is very bad for dogs (and humans) if ingested regularly.

Once mercury is ingested it is very difficult to eliminate it from our dogs’ bodies.

Your pup may experience all sorts of issues with his muscles since they would not be able to contract properly if the build-up is too large.

As a result there are other potentially serious health issues such as lack of mobility decreased digestive function and difficulty breathing. The situation is just as bad as it sounds.

The body of a fish also contains an enzyme called thiaminase. This naturally occurring enzyme breaks down vitamin B (thiamine) so your dog would not be able to absorb any of the essential vitamin B in his food. Your puppy cannot eat it because the enzyme eats it first.

As long as you cook your pups fishy meal the enzyme will be destroyed so vitamin B remains available for his body to absorb.

Furthermore fatty fish is high in calories so when you feed your dogfish its very easy to overfeed it. A cup of mackerel contains the same amount of calories as 344 cups of commercial kibble – about 300 calories. Limit his fish intake in order to control his calorie intake. Overweight dogs are not healthy – no one wants them. Depending on your pups size age and activity level he may need more or less fish in his diet. Busy large dogs require more food than tiny couch potatoes.

Make sure you do not have any allergies. Watch your pooch carefully for any adverse reaction when introducing fish into his diet. Remove fish from his diet if he shows any signs of discomfort. In addition introduce only one new thing at a time since you can then pinpoint the cause of any adverse reaction.

4. How should you prepare mackerel for your dog?

The thiaminase found in mackerel (which eats up all the vitamin B before your pup can consume it) makes it essential that you cook it. Because this enzyme dies when heated above 140 degrees F (60 degrees C) it would not interfere with the vitamin B your dog gets from his food.

The mackerel can be chopped up in a food processor after it has been cooked to make it easier to eat. Theres no need to worry about the tiny fish bones – they’re soft so your pup would not have any issues with them. Additionally the food processor will make them even smaller which will make the process even easier.

You could always make a yummy fish cake recipe like this one if you do not want to feed your dog plain fish but want to give him a gourmet snack. Its fun to figure out what your pup likes and who wouldnot like to spoil their furry friend with a healthy snack?

5. Can dog eat peppered mackerel?

Dogs can eat small quantities of pepper if they are prepared correctly and do not contain too much. So if you serve your pooch peppered mackerel make sure it is prepared correctly and does not contain too much pepper. However dogs are generally not all that fond of pepper so it does not necessarily mean they will enjoy it.

Make sure you read the label of peppered fish before giving it to your pup. You may want to skip it if it contains salt oil MSG (monosodium glutamate) or any other bad ingredients. The health of your pup is not worth putting at risk for a short-term reward.

6. Should dog eat mackerel in tomato sauce?

There are a number of additives in tomato sauce that are not good for dogs including salt sugar and oil. In spite of this tomatoes can be beneficial for dogs when consumed in moderation. Hence they should be fine if they consume a small amount of tomato sauce with their canned mackerel. As with most things moderation is the key.

Have a look at the ingredients listed on the can if you are not sure whether the tinned mackerel you got for your pup is safe. Are there a lot of salt preservatives and artificial flavors in it? Perhaps your pup should not consume it. Otherwise you should be okay.

Tomatoes are packed with antioxidants fiber and vitamins A and C all of which are beneficial for your pups skin teeth and digestion. I would say go for it if the tomato sauce in question is healthy (you know sans salt sugar and all the other nasties). I’m sure your pup will love it.

7. Should dog eat mackerel in brine?

Salinity is terrible for your pup and brine is saltwater. Rather than mackerel packaged in water use mackerel packed in tomato sauce. Packets of canned mackerel in saltwater add so much salt to your pups diet that he might as well be eating crisps. Not a good idea.


The Omega 3 fatty acids contained in Mackerel are essential for the long-term health of your dog. Although it may contain other nasties such as mercury it is also calorie-rich and contains a lot of calories.

You should use mackerel in moderation when feeding your pup. If there are any nasties on the label to avoid such as salt oil and other artificial ingredients found in processed foods check them out. You should also serve this treat well-cooked to your puppy to kill off the harmful enzymes that are normally found in fish.
