- Coffee contains caffeine which has stimulant effects on dogs. When consumed, it can make dogs feel more energetic and alert. Too much caffeine can be dangerous for dogs, leading to increased heart rate and blood pressure, muscle tremors, or seizures.
- Caffeine levels vary depending on the type of coffee. Coffee drinks made from roasted white coffee have more caffeine than black coffee, because of its higher caffeine content.
- Coffee with sugar and milk is not healthy for dogs because it can upset dogs' stomachs. When coffee is mixed with dairy products like milk, it becomes more difficult for dogs to digest. This can lead to diarrhea and vomiting.
