Legs may be bandaged with either disposable stretchable wrap that sticks to itself, or with washable fleece or cotton wraps that are reusable and fasten at the ends with a hook and loop closure. Bandages may also be taped with medical tape to help them stay on. Veterinary care There are many disorders that affect horses, including colic, laminitis, and internal parasites. Horses also can develop various infectious diseases that can be prevented by routine vaccination. It is sensible to register a horse or pony with a local equine veterinarian, in case of emergency. The veterinary practice will keep a record of the owner's details and where the horse or pony is kept, and any medical details. It is considered best practice for a horse to have an annual checkup, usually in the spring. Some practitioners recommend biannual checkups, in the spring and fall. Vaccinations and travel requirements Horses and ponies need annual vaccinations to protect against any number of sicknesses, though the precise vaccines required varies depending on the part of the world where the horse lives and the uses to which the animal is put. In most nations, rabies and tetanus shots are commonly given, and in many places, various forms of equine encephalitis are a concern as well as West Nile virus. Horses that travel or are exposed to other horses that travel are often recommended to receive equine influenza vaccines, since the disease is highly communicable. In the United States, many people also vaccinate against Equine Herpes Virus strains 1 and 4. Many additional vaccines may be needed, depending on local conditions and risk, including Rhodococcus equi (strangles), Botulism, or Potomac Horse Fever. As a general rule, a horse or pony that has never had a particular vaccination will be given an initial vaccination and then a booster a few weeks later, then normally once a year after that. Animals kept in a public boarding facility, those shipped for breeding and those frequently on the show circuit often require more vaccinations than horses that are not exposed to outside animals and who do not travel. Some type of veterinary certificate or proof of vaccination is often required for horses to travel or compete, especially when crossing state, provincial, or international boundaries. In the US, a certificate stating that the horse has a negative "Coggins" test must be in the vehicle carrying the horse when crossing state
