The following are general requirements for all dogs at Happy Trails Pet Center. Age All dogs enrolled in basic daycare must be at least three months of age or older. Sex All dogs enrolling in basic daycare must be spayed or neutered except for puppies under six months. We have allowed males that have not been neutered to play and socialize as long as they do not become obsessed with females or marking. Females must be spayed before their one year heat cycle. Canine Vaccinations Owners will be required to provide proof of current vaccinations (bordetella, rabies, and DHLPP vaccinations). Flea and heartworm preventatives are encouraged but not required. This should be discussed with your veterinarian. Pet Health All dogs must be in good health. Owners must certify that their dog(s) are in good health and have not been ill with a communicable disease within the last 30 days.
