Higher traffic stables and show barns should boost more. Talk to your vet to find out if you should be these vaccines as many of them are regional. In the fifth, seventh, and ninth month of pregnancy, vaccinate your pregnant mare foaling. At three months you'll boost your foal with the same vaccinations. At one year of age your foal is put into the adult vaccination schedule.
Horses chew in a sideways motion creating sharp edges to their teeth.
Eating can become difficult for your horse if these edges are left. Your horse needs to have his teeth inspected and possibly floated twice per year. At this time geldings and stallions need to have a thorough inspection of their sheath. You can clean your horse's sheath every few months or so but only your vet can do a thorough job. Your horse can develop serious infections if this area is not taken care of properly.
