Is chocolate dangerous for dogs?

Different dogs react to different things. Some dogs can tolerate human chocolate without any apparent ill effects. Other dogs will react very badly to certain foods and for some and it could kill them.

Dogs are masters at sniffing out chocolate and have been known to go to extreme lengths to access this tasty treat. Don’t imagine that just putting it out of reach is sufficient because if they want it, they will do their best to get it!

However, chocolate (particularly dark chocolate) can be extremely dangerous for dogs. Chocolate is the cause of death for numerous pets every year.

Chocolate contains a stimulant called Theobromine, which is similar to caffeine and is poisonous to dogs. Vets say that chocolate is one of the most common causes of poisoning in dogs. Not only can it make them extremely unwell, but it can also, in some cases, be fatal. Different types of chocolate contain different amounts of Theobromine. For instance dark chocolate contains the most, while white chocolate has very little. Despite this, it is still important to be aware of the risks.

Signs and symptoms of chocolate poisoning in dogs:

If my dog has snaffled my chocolate – what will the Theobromine do and what symptoms will I see?

Theobromine primarily affects the heart, central nervous system and kidneys. Symptoms will occur from 4-24 hours after your dog has eaten chocolate and will vary depending on the amount of chocolate (Theobromine) your dog has eaten.

Symptoms you may see:

• Vomiting (possibly including blood)
• Diarrhoea
• Hyperactivity and restlessness
• Rapid breathing
• Muscle twitching
• Increased heart rate
• Seizures / fitting

What the vet will do and first aid:

If your dog has eaten any chocolate contact your vet as quickly as possible. Be prepared to provide details about the amount consumed and the type of chocolate. Save any wrappers or remains and take them with you to the vet.

Unfortunately, no antidote exists for Theobromine. In most cases, vets induce vomiting, wash out the stomach, and administer activated charcoal to absorb remaining Theobromine. However, do not attempt to make your dog vomit yourself, as this should only be done by a vet in a controlled environment.

Please note that not all pets react to the same way to toxic foods. Some appear to tolerate grapes, raisins, chocolate etc. with no apparent ill- effects. There is no way to predict the effect foods will have on your dog and so it is always safest to avoid them entirely.

If you suspect your dog has eaten chocolate, even if they do not appear to be having any adverse reaction, always contact your vet for their advice. Your dog’s survival often depends on how quickly you act. Symptoms of poisoning can take hours or even days to appear, and by then, it might already be too late.
