As your horse gets long in the tooth, her needs change. If you know what to expect, you can give her the chance to age with dignity.

Aging weakens a horse’s immune system, so annual veterinary exams and routine vaccinations are more important than ever. Your veterinarian may also recommend diagnostic tests and can design a diet and exercise program for your equine elder.

Certain disease risks increase as horses age, so watching for signs of new health problems is crucial. Senior horses are more susceptible to colic, diarrhea, weight change, arthritis, hoof problems, endocrine disease and cancer. Equine teeth also change considerably over the years, so veterinary dental exams for seniors are recommended every six months.

Remember that being proactive can save you money and put a shine on your horse’s golden years.
