It depends on the dog's physical constitution and metabolic ability. Generally speaking, dogs cannot drink coffee. A large amount of high-purity coffee is very dangerous for dogs. If the dog only drinks a small amount of coffee and does not feel any discomfort after 2 hours, it means there is no problem. The breeder can feed the dog more water to help the dog excrete the coffee from the body. If your dog becomes excited or physically unwell, he should be sent to the hospital for treatment in time.
