My dog drank my coffee
If your dog drank coffee, monitor closely and call your vet if more than a small sip was consumed.
Coffee contains caffeine, which is toxic to dogs in higher amounts.
Emergency level
Moderate to high depending on amount and dog size.
A few licks from a mug is usually not an emergency.
A half cup or more, especially for small dogs, is more concerning. Call your vet.
A full cup of coffee, call your vet
Cold brew and espresso are much stronger and increase risk.
