Why grain-free dog food?

Grain-free dog food in some ways bring you some advantages.

Firstly, you do not have to worry about GMO sources of grains in the food, which is really not good for your puppy or pregnant dogs.

Secondly, reducing fiber and carbohydrates from grains means to increase protein sources. This may help your dogs to reduces gas and control intestinal system. This also help your puppy thrive and quickly gain weight to reach the expected body weight.

Thirdly, of course grain-free food is very helpful for grain-allergy dogs. In some case, grain-free diet helps your dogs quickly recover from food allergy which is not related to grain allergy.


How should we use grain-free dog food?                     

This question should be given to your veterinarian. According to Purina’s website, the number of grain-allergy in dogs is not over one percent. If your dog is not grain-allergic, the grain-free dog food should not be used for a long time as the only food. Because the wholegrains have many benefits to your dogs, we recommend using grain-free dog food with some add-ins to not only boost your dog’s body weight but also create a balanced nutrient strategy for your furry friend.



What are the downsides of grain-free dog food?

According to ASPCA (American Society for the Prevention of Cruelty to Animals), in the recent years, veterinary cardiologists noticed an increase in the number of dogs they saw who had dilated cardiomyopathy (DCM), a heart condition that decreases the heart’s ability to pump blood. Thus, Federal Drug Administration (FDA) began an investigation. FDA found that in 515 cases of DCM in dogs reported between January 1, 2014, and April 30, 2019, there were 90% were on a grain-free diet and 93% were on diets that contained peas and/or lentils. Those foods were tested for minerals, metal and amino acids but no abnormality was found. The conclusion is that though the relationship between grain-free food and DCM has not been fully proven, if your dog is going on a diet with grain-free food, the work of closely checking dog’s heart condition is necessary.

The other side of grain-free dog food is that grain-free does not mean low-carb. Some dog food manufacturers have chosen the carbohydrate alternatives from potatoes, sweet potatoes and pumpkins. Sometime carbohydrate rate of those grain-free foods goes over 20%. If your dog is not fed the suitable amount, he could get some unintentional kilos.


What are common whole-grain ingredients and its pros and cons?

The most common whole grains for dogs are oats, brown rice, barley, corn, millet and wheat. Whole grains mean the grains contain enough 3 parts of grain including endosperm, germ, and bran, in contrast to refined grains, which retain only the endosperm.

Looking at the bright sides, whole grains bring many advantages for your dogs.

It helps to fuel the dog with energy for various activities everyday.

It is also a various source of vitamins and mineral to add to your dog’s health and reduce the risk of some certain diseases.

Looking at the down sides, excessive grains do no good to your dog’s stomach – the animal whose ancestors are eating meat creatures.

Unhealthy grains are fully available on the market so it is also not good for your dog if we buy from manufacturers who could not control their sourcing initiatives.


What is the best add-ins for grain-free dog food?

Looking at both the dark side and the bright side of grain-free dog food, we think that the best way to balance your dog’s grain-free diet is to give him some add-ins.

Because the grain-free food is lacking whole grains and some kind of vitamin B and a little of fiber. The add-ins of fruit snacks, whole grains snacks which dog is not allergic to and vitamin B shall help. Of course, you should consult your vet to balance with the current dog food ingredients.
