A Comprehensive Guide to What Chihuahua Can’t Eat

Have you ever wondered what chihuahua can’t eat? As much as we love to spoil our dogs with treats, it’s important to know what human foods can be harmful to their health. In fact, there are many foods that you might enjoy but can be downright harmful, even fatal, to your little companion. So, before you slip them a bite of your sandwich or leftovers, let’s closely examine what Chihuahuas can’t eat and why. After all, prevention is better than cure.

Introducing Chihuahuas and Their Dietary Needs

what chihuahua can't eat

It’s important to remember that Chihuahuas are small dogs and have smaller stomachs. That means they require much less dog food than a large breed dog would need. They also won’t need their main meals as often as larger breeds. However, the quality of their food is still very important for nutrition, growth, and development purposes. Thus, as a pet owner, you should understand the dietary needs of your chihuahua.

➤Size, Age, and Weight

One of the most important factors to consider regarding a Chihuahua’s diet is its size, age, and weight. Chihuahuas are generally known to be small, so you must adjust their meal intake based on how much they weigh. The average Chihuahua weighs anywhere from 2 to 8 pounds. However, feeding them based on their weight alone might not be enough. You should also consider their age, which determines their energy levels and metabolic rate. Adult Chihuahuas should be fed 1/4 to 1/2 a cup a day, whereas puppies must be fed multiple times daily, 3-4 small meals until they are around 6 months of age.

➤High-Quality Protein

With their high energy levels, Chihuahuas require a diet high in protein. High-quality protein can come from sources like chicken, fish, turkey, or beef. Any meat should always be lean and cooked. Protein works to build and repair muscles, which is important for an active little dog like the Chihuahua. In addition, the high protein diet helps keep the dog feeling fuller longer, which can curb excessive eating and treat begging for food.

➤Complex Carbohydrates

Complex carbohydrates are responsible for providing energy to active dogs like Chihuahuas. The diet of your Chihuahua should have complex carbohydrates such as rice, oatmeal, or quinoa. This kind of diet will give the dog the energy they need to keep up with their active lifestyle. Feeding your Chihuahua simple carbs from processed food or treats can cause them to gain unnecessary weight as these carbs don’t provide sustained energy for them.

➤Fruits and Vegetables

Fruits and vegetables are a great source of essential vitamins, minerals, and antioxidants. They also provide the fiber that keeps their digestive system healthy. Fruits like apples, bananas, or blueberries are all great for Chihuahuas in moderation.

These should always be cut into small pieces and given as a treat. Vegetables like carrots, sweet potatoes, or broccoli are also excellent sources of fiber and nutrients for your chihuahua. These can be steamed or boiled to soften them up if needed.

1: Caffeine

Caffeine is present in popular drinks like soda, coffee, and tea. Dogs, including chihuahuas, are sensitive to caffeine. Caffeine stimulates the nervous system, leading to restlessness, rapid breathing, heart palpitations, muscle tremors, and even death in severe cases. Therefore, keeping your chihuahua away from caffeinated beverages at all times is essential.

2: Chocolate

Chocolate contains a toxic compound called theobromine. This compound is present in all types of chocolate, including dark, milk, and white chocolate. Theobromine can cause various health issues in dogs, such as vomiting, diarrhea, seizures, and even death. Therefore, you should never give chocolate to your chihuahua. Instead, there are many dog-friendly treats available that you can offer them.

3: Fruit Pits, Seeds, and Cores

While fruits are an excellent source of vitamins and minerals, some fruits’ pits, seeds, and cores can be dangerous for dogs. These parts of the fruit contain a compound called cyanide, which is poisonous for dogs. Therefore, you should always remove these parts before giving your chihuahua fruit. Some common fruits that contain pits, seeds, and cores are apples, cherries, and peaches.

4: Artificial Sweetener/Xylitol

Xylitol is an artificial sweetener commonly found in sugarless gum, candies, baked goods, and toothpaste. In dogs, Xylitol can cause insulin release, leading to hypoglycemia or low blood sugar. This condition can cause vomiting, loss of coordination, seizures, and even death. Therefore, keeping any foods with xylitol away from your chihuahua is crucial.

5: Allium Family

The allium family includes onions, garlic, leeks, and chives. These foods contain compounds that can cause damage to your chihuahua’s red blood cells, leading to anemia. Symptoms of anemia include weakness, lethargy, and pale gums. If your chihuahua consumes a large amount of these foods, it can lead to a life-threatening situation.

6: Currant-family Foods

Grapes and raisins belong to the currant family and are toxic food for dogs. This can cause kidney failure and can be fatal. Avoid giving them any food or snack that contains currants, raisins, or grapes. Other foods that belong to the current family are cherries, strawberries, and blueberries. While not necessarily toxic, they should still be given in moderation.

7: Sweets and Candies

Sugar, in general, is not good for your chihuahua’s teeth, and sweets and candies can cause tooth decay or even obesity if given in excess. Chocolate, specifically, is very harmful to dogs. It contains caffeine-like stimulants known as methylxanthines, which can cause vomiting and diarrhea, and in large amounts, they can cause abnormal heart rhythm and seizures can be fatal. Other sweets and candies, like gum, should also be avoided since they contain xylitol which can cause liver failure.

8: Onions

Onions are toxic for dogs as they contain a chemical called N-propyl disulfide that destroys red blood cells, which can cause anemia. Consuming a small amount may not cause harm, but it can accumulate in their system and lead to toxicity over time. Onions are used in many food preparations, so be careful with what you give them.

9: Cooked Bones

Chicken, turkey, or any other type of cooked bones can break easily and splinter during your chihuahua’s digestion process. These sharp pieces can cause issues in their digestive system. Cooked bones are a choking hazard and can cause internal blockages, which can be life-threatening. Instead, give them raw bones or approved dental chews designed for dogs.

Nutmeg is a common kitchen ingredient used as a seasoning in well-known recipes. However, it is toxic to dogs when consumed in large amounts. This spice contains myristicin, which can cause hallucinations, increased heart rate, stomach pain, and disorientation in dogs. When used in small amounts, it may not harm your Chihuahua, but it’s best to avoid giving it to them altogether.

12: Avocado

Avocado is a superfood for humans; it’s packed with many nutrients that can benefit our health. Unfortunately, it’s not suitable for dogs, including your Chihuahua. Avocado contains persin, which is toxic to dogs and can cause vomiting, diarrhea, and even heart congestion. It’s best to avoid giving them guacamole, avocado, or any other food that contains this fruit.

13: Mustard Seeds

Mustard is a common spice found in our kitchens. However, mustard seeds are not suitable for dogs because they contain isothiocyanates that can cause gastrointestinal issues, including vomiting, diarrhea, and abdominal pain. These seeds can also irritate their skin, leading to burning or painful sensations.

14: Coconut Oil and Coconuts

Coconut and coconut oil have become a natural remedy for humans, but when it comes to dogs, it’s a different story. Large amounts of these products can cause diarrhea and upset stomachs in dogs. Coconut oil is high in fat, which can lead to obesity and pancreatitis. Raspberry ketone, found in coconut, has also been linked to reducing a dog’s metabolism, which can lead to weight gain and serious health problems.

15: Dairy Products

Products such as milk, cheese, and yogurt can cause digestive issues in dogs, including your Chihuahua. Dogs do not produce enough lactase enzymes to break down the lactose in milk products. Consuming too much lactose can lead to bloating, gas, and diarrhea. It can also cause allergies in some dogs, leading to inflammation, rashes, and skin irritation.

As much as we love blue cheese in our salad or pizza, it is not recommended to give it to your chihuahua.

If you must give your chihuahua cheese, opt for cottage cheese or mozzarella, which are low in fat.

Chihuahuas are prone to obesity, and too much fat in their diet can contribute to this health problem. Foods like bacon, sausages, and fried chicken are high in fat and sodium and should be avoided. These foods may also cause pancreatitis, a serious inflammation of the pancreas.

20: Any Salty Foods

Salty foods such as chips, pretzels, and popcorn can harm your chihuahua as they can cause excessive thirst and urination. Too much salt in their diet can also lead to kidney problems. If you want to give your chihuahua a crunchy snack, try offering them fresh veggies like cucumber or carrot sticks.

21: Yeast Dough

It is often used in bread and pastry recipes and can be a major problem for your Chihuahua if ingested. When your Chihuahua ingests yeast dough, it expands in the stomach and produces gas. This can cause the stomach to bloat, a serious and life-threatening condition. Signs of stomach bloat include vomiting, abdominal pain, and restlessness. To prevent this, keep any yeast dough out of reach of your Chihuahua.

Medications that are safe for humans are not always safe for pets. Never give your Chihuahua any medication without consulting with your veterinarian first.
