We understand that there are many important factors that go into making the decision to alter your dog. Recently, there has been veterinary research that reports some benefits from waiting a little longer to spay or neuter than previously recommended for some breeds. There are also benefits to spaying and neutering before dogs become fully mature. At Dogtopia, we are focused on the health and safety of all the dogs that come play with us. Our main reason for requiring dogs to be altered is to reduce the potential levels of aggression that hormones can create. It is not always the un-neutered male that can create the tension; detectable hormones released by an intact dog can trigger other dogs to become more aggressive. Additionally, we have the reproductive concern for dogs in open play.
