Let's talk Smooth-Coat Chihuahuas

When choosing food for a Chihuahua, there are many factors to consider: their age, lifestyle, activity level, physiological condition, and health including potential sickness or sensitivities. Food provides energy to cover a dog’s vital functions, and a complete nutritional formula should contain an adjusted balance of nutrients to avoid any deficiency or excess in their diet, both of which could have adverse effects on the dog.
The following recommendations are for healthy animals. If your dog has health problems, please consult your veterinarian who will prescribe an exclusive veterinary diet.
Clean and fresh water should be available at all times to support your dog’s urinary health. In hot weather and especially when out exercising, bring water along for your dog’s frequent water breaks.

A Chihuahua puppy’s requirements, in terms of energy, protein, minerals, and vitamins, are much greater than those of an adult dog. They need energy and nutrients to maintain their body, but also to grow and build it. Until they are 8 months old, a Chihuahua puppies’ immune system develops gradually. A complex of antioxidants - including vitamin E - can help support their natural defences during this time of big changes, discoveries, and new encounters. Their digestive functions are different from an adult Chihuahua’s, too: their digestive system is not mature yet so it’s important to provide highly digestible proteins that will be effectively used. A balanced intake of fibres, such as psyllium, can help facilitate intestinal transit and contribute to good stool quality.

Similarly, a puppy’s teeth – starting with the milk teeth, or first teeth, then the permanent teeth – are an important factor that needs to be taken into account when choosing the size, form, and hardness of kibble. This growth phase also means high energy needs, so the food must have a high energy content (expressed in Kcal/100g of food), while concentrations of all other nutrients will also be higher than normal in a specially formulated growth food. It is recommended to split the daily allowance into three meals a day until they are six months old, then to switch to two meals per day.

The main nutritional goals for adult Chihuahuas are:

Maintaining an ideal body weight by using highly digestible ingredients and keeping the fat content at a sensible level

Preserving the health and beauty of the skin and coat with the enriched provision of essential fatty acids (especially EPA-DHA), essential amino acids, and B vitamins.

Protecting their very delicate jaws. Chihuahuas have a strong predisposition to accumulating dental tartar. By reducing tartar formation on the teeth, which is responsible for dental plaque, kibble containing calcium chelators plays an essential role and helps combat oral disorders. The size and shape of the kibble should be very small and adapted to the miniature jaw of Chihuahuas in order to avoid problems with picking up food. This may also stimulate their fussy appetite.

After 8 years old, Chihuahuas start facing the first signs of ageing. A diet enriched with antioxidants helps maintain vitality, and key nutrients, such as taurine, help support good cardiac function. Ageing is also accompanied by the modification of digestive capacities and particular nutritional requirements, so food for ageing Chihuahuas should have the following characteristics:

Higher
vitamin C and E content. These nutrients have antioxidant properties,
protecting the body’s cells against the harmful effects of the oxidative stress
linked to ageing.

High-quality protein. Contrary to a widely held misconception, lowering the protein content in food brings little benefit in limiting kidney failure because older dogs are less efficient at using dietary protein than younger dogs. Reducing the phosphorus content is the only way of slowing down the gradual deterioration of kidney function.

A higher
proportion of the trace elements iron, zinc and manganese to maintain good
condition of the skin and coat.

A higher
quantity of polyunsaturated fatty acids (borage oil, fish oil) to maintain the
quality of the coat. Dogs normally produce these fatty acids, but ageing can
affect this physiological process.

As they age, dogs increasingly suffer from teeth problems. To ensure they continue to eat in sufficient quantities, the shape, size, and hardness of their kibble needs to be tailored to their jaw. A formula that contains calcium chelators will support dental health by reducing tartar formation.

Although important throughout the Chihuahua’s life, cardiac health becomes more important as the dog ages. A blend of nutrients, such as taurine and EPA-DHA, will help maintain cardiac health in mature Chihuahuas.
