Fish oil is high in calories

Fish oil for dogs includes fatty acids and is therefore high in calories. Fat has 2.25 times more calories than protein or carbohydrates. So if your dog has weight problems, then you may want to reduce accordingly the amount of calories he gets from his diet.

Fish oil not fish liver oil

Bear in mind that fish oil and cod liver oil is not the same. Fish stores fat either in the body or in the liver. The best fish oil for dogs comes from fish that stores the fat in the body, like salmon, tuna, mackerel, sardines and menhaden.

This is because fish also store Vitamin A and D in the liver. Meaning supplement containing fish liver oil contain high level of those vitamins. Excessive levels of Vitamin A and D can harm the liver and using fish oil, not fish liver oil, eliminates the risk of accidental overdose.

The fish oil used in maxxiomega is from menhaden but it stores the fat in the body.

Fishy dog smell

Maybe the most annoying fish oil side effects for dogs are fishy breath or fishy smelling skin.

One of the frequently mentioned benefits of maxxiomega is that it does not leave fishy smell. This is because maxxiomega does not only contain fish oil for dogs, it also contains vegetable oils for additional health benefits.

Inflamed pancreas is another potential fish oil supplement side effect. This is fortunately extremely rare but the symptoms include vomiting, diarrhoea, pain, and dehydration.

The benefits of fish oil for dogs outweigh the potential side effects
