What Does Caffeine Do to Dogs?

Caffeine is a type of stimulant, which humans can tolerate but dogs cannot. Caffeine from products like coffee grounds and a tea bag wake humans up, but it can make dogs hyperactive and cause an elevated heart rate.

It can make dogs restless and jittery, potentially also becoming more vocal. More serious symptoms include seizures or tremors and loss of muscle control. 

Moreover, caffeine can raise blood pressure in pets. This rise in blood pressure and heart rate can cause cardiac arrhythmias, a potentially dangerous condition. It can be more serious if your pet already has other conditions, such as obesity and diabetes. 

Caffeine can irritate the gastrointestinal tract. The irritation can lead to diarrhea, excessive urination and vomiting. The vomiting can be a good side effect because it can help remove some toxins, but the dog will still need to see a vet. 

Caffeine also makes dogs very thirsty, especially if they vomit. Try to keep your dog hydrated until they see a vet. Coconut water may help in a pinch if you are on your way to the vet to hydrate your pooch.

How Do You Treat Caffeine Poisoning?

Ideally, you should bring your dog to the vet if you notice any symptoms of caffeine poisoning. The exact treatment will depend on the severity of your dog’s symptoms and other conditions. Luckily, most treatments are very effective to treat the toxicity.

Common Treatments

  • Induced Vomiting
  • A veterinarian may perform emesis on your pooch. The procedure makes the dog vomit, helping them get rid of any toxins that might still be in their stomachs. They may give your pet IV fluids after for rehydration.
  • Gastrointestinal Decontamination
  • This procedure is another method to clear out any toxins left in the dog’s stomach. A tube gets used to flush stomach contents out to prevent further poisoning. They may also offer activated charcoal to remove the toxins.
  • Treating the Central Nervous System
  • A dog’s central nervous system can experience central nervous system depression because of the stimulant, causing symptoms like seizures. A vet will likely administer different medications to treat the central nervous system to stabilize your dog. 

In some cases, a vet may only need to perform 1-2 of these procedures on your dog, especially if they only have mild symptoms of caffeine poisoning. However, your dog may need all of these treatments, and potentially more, if they show more moderate to severe caffeine poisoning symptoms.

What Does Sugar Do to Dogs?

Most processed sugar, which you can find in soda, is bad for dogs. It is not toxic to dogs, but pet owners should be wary of it. Dogs need sugars from carbohydrates like humans, but this is often a more wholesome source that they can find in their dog food.

For instance, foods like whole grains have natural sugars that are great for canines. However, processed sweeteners are bad for dogs because they can cause spikes in their blood sugar levels.

Dogs are more sensitive than humans, so some simple sugars, even from store-bought peanut butter, can be very harmful to them. So, pet owners need to watch out for their sugar intake.

For example, one tablespoon of sugar may not seem like much to a person. However, one tablespoon that can be more than enough to produce negative symptoms in your dog.

If your dog has a bit of sugar, it may have some mild symptoms. They may be very hyper, restless and jittery because of the sudden sugar rush. They may experience a “sugar crash” once the sugar wears off, making the dog fatigued, hungry, irritable, etc.

How It Affects Canines Versus People

One can of most commercial brands of soda contain as much as 30 grams of sugar. 30 grams is way too much for any dog, and it is even a lot of people to consume.

There is no exact amount of sugar that is bad for dogs. However, dogs should avoid sweet foods and drinks at all costs. Dogs cannot even have a lot of fruit. So, processed sugar is worse for them.

Diabetes in Canines

If a dog frequently has excessive sugar in its diet, it can lead to diabetes. It can also occur if the dog consumes too many sweets in one go because of the extreme blood sugar spike. Diabetes is often a life-long condition that requires specific medical treatment to keep the dog healthy. 

There are two kinds of diabetes, which are insulin resistance and insulin-deficiency diabetes. They require different treatments, but they both cause the same harmful side effects.

The high sugar levels in a dog’s bloodstream can damage its organs. The body will find it difficult to use glucose, an important fuel source for energy. 

How to Treat Excessive Sugar Consumption in Dogs

The exact treatment that your dog will need depends on how much sugar they ate and other conditions that they may have. Some veterinarians may induce vomiting and give other medications to remove the excess glucose from the body.

If your dog ate a lot of sweets, your veterinarian will likely check if your pooch developed diabetes. If that is the case, they will give your dog the necessary medication right away. 

Moreover, the vet will likely teach you how to treat your dog’s diabetes at home with medicine , a change of diet, etc. Most pet owners will have to learn how to adminster insulin to their pooches at home.

However, you may have to be cautious if your dog drinks a cup or more soda in one sitting, especially if they are a small dog.

How Much Soda Is Too Much for Dogs?

There is no exact amount as to how much soda you can give your dog, but all dog breeds definitely should not have carbonated beverages in general. A few licks off the floor by accident can happen, and your dog may be fine.

However, if you give your dog even half a can of soda, your dog can develop some serious issues and even death, depending on the size of your pet.

For instance, a medium-sized dog breed can develop symptoms after they consume 1-2 cups of soda. The amount of caffeine and sweetener in 1-2 cups of soda is enough for mild symptoms to appear.

A whole bottle of soda can easily produce moderate to severe symptoms and other signs of toxicity, especially if pets consumed that amount in one day.
