<P> Overall, the Shiba Inu is a healthy dog breed . Health conditions known to affect this breed are allergies, glaucoma, cataracts, hip dysplasia, entropion, and luxating patella . Periodic joint examinations are recommended throughout the life of the dog but problems are generally discovered early in the dog's life . Eye tests should be performed yearly as eye problems can develop over time . By two years of age, Shiba Inus can be considered fully free from joint problems if none have been discovered by this point, since at this age the skeleton is fully developed . </P> <P> As with any dog, Shibas should be walked or otherwise exercised daily . </P> <P> Their average life expectancy is from 12 to 15 years . Exercise, especially daily walks, is preferred for this breed to live a long and healthy life . The oldest known Shiba, Pusuke, died at age 26 in early December 2011 and was the oldest dog alive at the time . </P> <P> These dogs are very clean, so grooming needs will likely be minimal . A Shiba Inu's coat is coarse; short to medium length with the outer coat being 2.5 to 3.2 cm (1 to 1 ⁄ in) long, and is naturally waterproof so there is little need for regular bathing . They also have a thick undercoat that can protect them from temperatures well below freezing . However, shedding, also known as blowing coat, can be a nuisance . Shedding is heaviest during the seasonal change and particularly during the summer season, but daily brushing can temper this problem . It is recommended that owners never shave or cut the coat of Shiba Inu, as the coat is needed to protect them from both cold and hot temperatures . </P>
