Most pet parents are aware that chocolate is toxic, but did you know that it’s the amount and type of chocolate that determine the toxicity? While one small chocolate chip from one cookie is not a problem for your pet, certain types of chocolate are very toxic – this includes everything from a pure chocolate bar to chocolate-flavored sweets.
Why is chocolate toxic to my pet?
Chocolate is a mixture of cocoa beans and cocoa butter. In its various forms, chocolate contains theobromine and caffeine, which are both classified as methylxanthines. While humans have the ability to metabolize methylxanthines quickly, our pets ability to metabolize methylxanthines can be 20 times slower – which can result in a toxic overdose.
The amount of methylxanthines present in chocolate varies with the type of chocolate. One key fact to remember is the darker and/or more bitter the chocolate, the more toxic it could be.
What types of chocolate are toxic?
The simple answer is all types of chocolate can be toxic to a pet. However, certain types of chocolate carry a higher toxicity
than others.
Baker’s chocolate, semi-sweet chocolate, cocoa powder, and gourmet dark chocolates are more dangerous than milk chocolate. White chocolate has very little theobromine and is least likely to cause chocolate poisoning in pets.
