Dog birth control is to prevent some pets from disturbing themselves or others' lives because of estrus. When the female cat in the pet is in estrus, it will constantly make a spring cry, and often make a crazy cry in the middle of the night, disturbing people's dreams. Pregnant cats are in heat more than once a year, and each time they are in heat for several days, it will cause great interference to the rest of their families and neighbors. For a dog-owning family, if the bitch is in heat, it may attract those amorous male dogs to come over, urinate and defecate everywhere, and it's annoying to fight fakes. The sex hormones produced by pets in estrus will make them anxious, and when they are sexually frustrated, they will have symptoms such as biting, destroying furniture or being grumpy. Birth control can help pets overcome these problems.
