If your dog is in this case, it will certainly show several signs, like decreasing appetite and thirst, the shortage of energy, diarrhea and other changes in the body shape.

Sometimes, you think that your pet is underweight just because he is less heavy than his same breed friend. However, your dog may be actually fine, whereas the other is obese!

#2 Take a Look at the Packaged Food

For the thin dogs that produce formed feces and are abundant in energy, check whether they get enough calories each meal. The number of used calories is beyond than the absorbed calories may be one of the main reasons. In this case, increasing his portion will do the trick. To do this simply, you should follow the suggested feeding that a food packaging tells.

If your pet is a special breed, there is a large amount of information online about the ideal weight of each breed. It’s better to go with the weight that you want your dog to be than its present weight. For example, the ideal weight of a male Labrador at the average size is 40kg.

#3 Re-Check the Amount of Food You Feed Your Dog

Making a list and a note of the food that is good for your dog. Remember to follow the recommended amount on the food packaging. Interestingly, some of those recommendations are usually 25% exceeding what the dog needs. They tend to appear on the generous side regularly than in the skimpy side.

To more detailed, if you feed your Labrador about 400 gr of kibble per day, whereas the packaging recommends 500 gr per day, it means your dog supplied calories is 20% less than the recommended ones.

As a result, it’ll lose weight. Fortunately, this will be easily improved by increasing his daily food ration.

#4 Make a Decision on Increasing the Food Allowance of Your Dog

This may be hard for you to decide since each food contains a lot of calories. As a rule, increase the food no more than 10% the original quantity. If you feed your dog 400 gr per day, just add another 40 gr (maximum amount), remember to split the addition equally into two meals.

Keeping this diet for 2-3 days, then check your dog whether it has diarrhea or not. If not, you can increase another 10% and keep going.

#5 Gradually Increasing, Not Suddenly

Abruptly feeding more food to your dog will disturb the balance of its bowel as well as causing diarrhea. So, it’s safer for your pet to be slowly increased the portion size. By this way, diarrhea will be controlled easily.

You should divide the extra between 2 meals if the difference in the portion isn’t large. In case the difference is large, providing the extra meal is gentle for its bowel than keeping the bigger difference.

Keep in mind that if your dog gets diarrhea and loses precious nutrient, your effort will be for nothing!

Step 3: Changing the Diet of Your Dog

The liver is extremely abundant in vitamin B12. So, cooked chicken liver or cooked beef twice a week as an extra snack is ideal for the dog. For example, a 10-kg dog should be fed about 50-70 gr of cooked liver.

Eggs are also rich in vitamin B2, B12, A, iron and fatty acids. Giving your dog raw eggs and adding one egg third a week.

Again, bear in mind that increasing this food gradually do not harm your dog’s stomach.

#2 Divide into Small Meals Often

Build up a scientific schedule of meals for your dog. Let him eat 4-5 small meals throughout a day rather than 2 or 3 big meals. Thanks to this, he’ll digest his food easier as well as absorb the nutrition more efficiently.

When you give him smaller meals instead of big ones, fix a big normal meal and then split it into many smaller meals to feed. This will show you how much you feed till you accustom to the new routine.

A small meal every hour is great; however, more than 6 hours between meals per day should be avoided.
