What to take to suppress dog estrus can be suppressed with progesterone or oxyprogesterone at a dosage of ¼ tablet per dog. Both of these medications are recommended to be taken before the dog goes into heat, and neither is effective when used during heat. Dogs in heat are recommended to be spayed if there is no intention of breeding. Long-term feeding of estrus-inhibiting drugs to dogs can cause diseases such as arteriosclerosis, ovarian hemorrhage, and ovarian augmentation in dogs. It is a medicine that is poisonous, so please consider it carefully. There is no suitable estrus suppressant medication for dogs, so I hope that owners will not get drunk on this, but choose to breed or neuter as soon as possible.
