In the first step, the veterinarian will inject sedatives to put the dog to sleep, which usually takes several minutes to take effect. After the dog falls asleep, the veterinarian will immediately inject a second lethal agent, which usually takes a few seconds to complete.
Generally speaking, generally speaking, the whole euthanasia process takes about 10-20 minutes. However, if the dog has a strong heart or extremely weak body, it may lead to different effects of injecting drugs, which may lead to different euthanasia time.
Finally, it should be pointed out that euthanasia of dogs is a very sad decision, which must be made after careful consideration and consultation with professionals. At the same time, always treat pets in the most merciful way and help them finish their last journey.
