Can my dog eat coffee grounds?کافی
No.
Grounds and beans are far more concentrated than brewed coffee, and bin-raiding is how most dogs get them.
Already ate it?
If they ate itCall a vet with your dog's weight and roughly how much. Take the jar, packet or used filter with you. Don't make them vomit unless a vet tells you to.
Watch forRestlessness, pacing, a racing heart, tremors — usually within an hour or two.
Thinking of giving it?
Why not even a littleSigns start from about 20 mg of caffeine per kg of body weight, serious heart effects from 40–50 and seizures from about 60. A teaspoon of instant coffee carries roughly 60 mg; a tablespoon of ground coffee 60–100 mg; used grounds a bit less.
WhyCaffeine causes restlessness, a racing heart, tremors and seizures. A dog will happily eat used grounds straight out of a bin.
