Health benefits of tuna to your doggy

As we have discussed earlier, eating tuna is beneficial to the dog.

Here are some of the reasons why including tuna in her diet is a good thing;

a) Tuna being a fish is a great source of protein

Protein is useful in muscle growth. The fact that tuna has low levels of fat makes it the ideal dish for dogs.

Dogs usually have low levels of protein in their body and they could easily crack up without the owner’s knowledge.

This is why certain levels of protein intake is necessary for their body building processes.

Too much protein however may cause workload on the kidney leading to imbalance of nutrients therefore a high risk of diseases such as kidney failure.

Since the kidneys have a low tolerance for excess proteins, metered amounts are the best option for her.

b) Tuna is rich in minerals

Some of these minerals include; phosphorus and magnesium which help maintain normal body functions.

c) Omega-3 bring about cardiovascular benefits

Tuna being a fish is rich in omega-3.

The Omega-3 available in it helps:

  • reduce chances of irregular heartbeats
  • balance cholesterol levels in the body
  • reduce chances of blood clot and
  • control the inflammation of the blood cell walls.

Cardiovascular benefits help reduce chances of arrhythmia in dogs (a disease that is caused by irregular heart impulses resulting to an irregular rhythm).

Without a doubt, tuna seems to be a good fish for your dog.

The question is, does it have its snags?

Precautions when feeding your dog tuna

The good news is that dogs are naturally born carnivores making it easier for them to eat their way through any meat without stomach upsets.

However, precaution should be taken in most cases since fish is a delicate food and needs to be handled with extra care.

It is advisable to accompany tuna with other normal dog feeds for example; dog biscuits.

This is because the bones in tuna may get stuck between the dog’s teeth. This causes irritation and dental problems to the dog in case the debris stay stuck up there for too long.

As a precaution, the biscuits will help remove the tiny pieces of bones which will thereafter ease the discomfort in her mouth.

Additionally, you should be cautious when feeding her with tuna since it has high levels of both proteins and fat.

This may cause adverse reactions in her body especially for the first time.

Try feeding her sizeable portions so that you can give her digestive system time to adjust accordingly.

Although canned fish is great for your dog, it is always advisable to check the label for any additives and make sure they don’t cause any trouble to your furry friend.

Try picking canned tuna that doesn’t have sauces, flavors or any that has been canned in oil.

Some dogs may have negative reactions to flavors and sauces for example; the additives may cause digestive breakdown.

The oil isn’t healthy for you dog as well because it may cause excessive weight gain.

So…Is tuna for dogs?

In conclusion, tuna is as good as any other dog food as long as given in moderation.

It is always necessary to check with your veterinary doctor before incorporating tuna in your dog’s feeding schedule.

This will help curb any adjacent reactions in case of allergy.

A special treat of tuna occasionally will always be appreciated by your doggy.

But remember better serve it in a plain cooked form.

It’s always safer that way!
