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.

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.

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.
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.
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.
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.

Best air dried food

Ziwi Peak Air Dried Mackerel and Lamb Recipe

Pros

Delicious sustainably sourced and air dried Blue Mackerel and New Zealand Lamb
Grain free with no artificial colours or preservatives
Added Green Mussel for joint and mobility support

Cons

Expensive in comparison to other dry foods
Freeze-dried foods may not be as safe from bacterial and parasitic contamination as foods cooked with heat
Very calorie dense, so may contribute more to weight gain if overfed

Why we love it

Air-dried to retain raw nutrition, all Ziwi recipes are high in meat, organs and bones with beneficial inclusions like green-lipped mussel. With complete and balanced recipes, they are also grain free and all ingredients are sourced sustainably. Ziwi recipes are highly palatable, making them a great choice for fussy eaters.

Ziwi-Peak dry foods have a firm jerky texture, so are an excellent choice as treats, for training or as a topper to provide variety to other foods.

Ziwi-Peak dry foods should be stored in their original packaging after opening, and away from direct sunlight and high temperatures.

Like freeze-dried foods, the air-drying process is not an equal substitute for cooking with heat in terms of bacterial and parasitic control, so extra caution must be taken in the handling of air-dried foods and hygiene control.

What our customers say

"My toy poodle has been on Ziwi Peak for six years. Her coat is excellent, poops firm and her gut has remained calm. 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 years."

In addition to the nutritional requirements needed for their small size, Chihuahuas can be quite fussy with their food, so make sure to pick kibble suitable for their small mouths. Given their long lives, it's imperative to choose a premium quality diet that has added heart, digestive, and joint support. Premium foods are trustworthy and contain beneficial nutrients. 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. Look for dry dog food that is highly digestible, with a variety of proteins and formulations to tempt even the fussiest of dogs. Small Breed dogs like Chihuahuas have specific needs including much smaller kibble, appropriate nutritional profiles, ingredients to help reduce tartar and joint support.
