An injury or illness affects directly the dog’s ability to be exercised as normal which means that this affects too how many calories need a dog.

However, there are some exceptions. For example, pregnant dogs need a big amount of calories, especially for the second half of pregnancy, also nursing dogs that need a big boost of calories to fuel milk production, a pregnant dog will need 25 percent more calories than a normal dog by the time she is ready to give birth. a chi that is nursing puppies will need about 15 percent more calories each day for each puppy, then, with a litter of three pups, she will need 45 percent more calories.

2. Age:

Age is a huge factor, for example, we should notice that a puppy needs more calories compared to an adult.

The growth in a short time means the need for a lot of calories. Chihuahua newborns double in size with days. when a chihuahua is 1-year-old she or he is considered to be an adult, so calorie needs will change at that time.

When a chihuahua becomes a senior dog, he often needs fewer calories than his younger counterparts, this is because the dog exercises less.

3. Activity level:

Every second dog burns calories even when they are sleeping. In other words, the rate of calories that are burned throughout the day is not the same. Activities in a dog’s life are so crucial because without any activity your dog will be at a high risk of getting sick or suffering from a health issue such as obesity, depression, etc.

4. Diet’s quality

Some owners think that the quantity of food is crucial, it is but the quality is an important part too. All dogs including chihuahuas need a balanced amount of protein, minerals, vitamins, and healthy carbohydrates. While adult chihuahuas may need fibers, protein, and probiotics for their digestive system and nourishing muscles. Puppies will need Omega Fatty Acids, DHA, to help them grow in a healthy way.

Some chihuahua owners prefer to feed their dogs homemade dog food meals. However, it is advisable to seek for your vet’s advice to see if your dog needs some supplements to be sure that he is getting all the calories he needs.

There are 2 activity types that affect the number of calories burned.

1. exercise:

There have not been a lot of studies done, but we have some rules, for example, a 20-pound dog walking for 15 minutes at a good pace 4 miles/hour will burn 64 calories. therefore, a recommended 30-minute walk would equal 128 calories.

If we apply this to a chihuahua, a 5-pound chi walked at a toy breed’s pace of 2 miles/hour for a calorie burn of approximately 25 calories.

2. NEAT:

This refers to the calories a body needs even at rest and sleep, in order to maintain itself a body burns calories.

Naturally, there are some dog breeds that are super active. This means that they will burn an incredible amount of calories without counting exercises and programmed activities and animated ones such as playing, walking outside, etc. If you are the parent of a very active dog, you will notice that he has a very high metabolism.

Does neutering or spaying affect a chihuahua’s calorie needs?

A lot of people think that dogs gain weight after being fixed, so they think that their dogs may need fewer calories if he or she has been fixed.

The answer is that a dog may be less active due to urges to take a chase, to run away, etc. So, the number of calories burned by a dog carrying out his hormonal urges is very minimal.
