What is the Best Dog Food for my Chihuahua?


This article is written by Pet Circle's qualified veterinarian, Dr Emilee Lay BVSc BSc Vet Hons

Chihuahuas take on the title of the smallest dog breed in the world, but their pocket size stature doesn't mean they aren't sassy, fierce and smart! As a loyal and lifelong companion it is essential to provide optimum nutrients to fuel their tiny bodies and larger than life personalities. 

Why is choosing the right food important?

Given that Chihuahuas can live up to 18 years of age, providing the optimal premium nutrition to support their health is key to their longevity. This starts from puppyhood all the way to their golden twilight years. Chihuahuas like many small breed dogs do have a reputation for being fussy with their food. Choosing food that not only benefits their health but can tempt even the fussiest of pooches is essential. 

Four reasons why it's important to choose the right dry food are:
  1. Complete and Balanced: Dry foods are more nutritionally dense and completely balanced - compared to home-cooked diets, meaning it's convenient to feed, but also you can rest assured that your Chihuahua is getting everything they need. 
  2. Kibble Size: Having smaller and sometimes abnormal jaws means they need smaller kibble to help chew their food easier, this is especially important as Chihuahuas are particularly prone to dental disease. 
  3. Age: Small breed dogs of different ages have very different nutritional requirements. Puppies require energy-dense food which meets their intense growth rates, while senior dogs are often less active have a slower metabolism which means that they require fewer calories and less fat, but an easily digestible diet, to help them maintain good body condition.
  4. Health: Given their longer lifespans, small breed dogs are prone over the course of their lives to heart, mobility and gastrointestinal issues. Many dry foods have a wellness range to target these issues. In addition, prescription diets are now readily available to help manage these conditions.

Previous pets (prior to Ziwi) over the decades have suffered from dodgy tummies but Ziwi has been a consistent benefit for general health and satiety (they eat less) with only benefits over the year"

What to look for when choosing dry food for your Chihuahua

Chihuahua's can be quite fussy with their food. In addition to the nutritional requirements needed for their small size, make sure to pick kibble suitable for their small mouths. Having such long lives, its imperative to choose a premium quality diet, that has added heart, digestive and joint support!

High Quality Premium Food

Premium foods are not only trustworthy but contain beneficial nutrients above and beyond what is required. Look at the quality control processes and product safety records of the food you intend to feed. Assess if their formulations are designed by a qualified animal nutritionist or veterinary nutritionist. 

Complete and Balanced

In choosing a food, the most important consideration after any health factors is that the diet is complete and balanced for your dog's stage of life. Ensuring that it meets AAFCO or FEDIAF pet food control guidelines is crucial to ensure that your dog receives all the nutrients they require in the correct ratios. Being such tiny dogs Chihuahuas have a much high energy requirement. 

Digestibility and Palatability

Look for dry dog food that is highly digestible. This means the nutrients are readily absorbed and utilised by your dog's body. Good digestibility is often indicated by high-quality ingredients and the absence of excessive fibre content. Learn more about the ingredients in your pet's food. Look for foods with a variety of proteins and formulations to tempt even the fussiest of dogs. 

Consider the Specific Needs of Your Chihuahua

Small Breed dogs like Chihuahuas have specific needs including much smaller kibble, appropriate nutritional profiles, ingredients to help reduce tartar and joint support. As Chihuahuas are also prone to heart disease - a diet rich in omega fatty acids and low in salt is also important. Some dogs may have special dietary requirements due to health conditions or sensitivities. If your dog has specific dietary needs, consult with your veterinarian for specific recommendations.
