Toxic Foods For Dogs And Cats - PugsTime

Cats are true carnivores, which means they rarely prefer something different other than meat, milk, and products containing these.

Conversely, unlike cats, dogs are omnivores (just like us humans!), which means that besides meat, dogs also eat vegetables and fruits for a balanced diet.

There are a number of common foods that dogs and cats should never eat no matter how cute they are staring at you when you are eating – including the following:


All types of chocolate, such as white, milk or dark all contain Theobromine (cardiac stimulant and diuretic), which is toxic for both cats and dogs.

According to, dark chocolate is a healthy option for humans but is actually the most toxic type of chocolate for cats and dogs.

Clinical Signs

The clinical signs, which indicate a cat or dog has consumed chocolate can include:

  • Initial excitation
  • Increased need for water
  • Increased urination
  • Vomiting
  • Diarrhoea

If the amount of chocolate ingested was high, you may see an increased heart rate followed by arrhythmia, seizure, and in the most severe cases, even death caused by cardiac arrest.


Besides chocolate, coffee is also harmful to dogs & cats. Coffee contains caffeine and dangerous components, such as xanthines, which can damage the nervous and the urinary system of your pet.

Caffeine can also be found in a number of other products, to name a few: tea, energy drinks, fizzy drinks, caffeine pills, chocolate, some prescribed medication, and even some breakfast cereals.

Clinical Signs

Some of the clinical signs will include in-coordination/ataxia (a neurological sign showing a lack of voluntary coordination of the muscles), excitement (due to the sugar in these products), depression, a slowed breathing rate, and in serious cases even cardiac arrest and death.
