This senior horse presented for the evaluation of nasal discharge. He was severely underweight, weighing approximately 300lbs less than he should. He had a Body Condition Score of 2/9, despite the owner believing they were feeding the horse adequately. We want to emphasize the fact that age is not a disease. Horses should not be skinny just because they are old - it is either because there is an underlying condition or because they are not being fed properly.
Upon oral exam, this horse’s teeth had excessive wear due to geriatric attrition, meaning his teeth were quite smooth with very little grinding surface. There was rotting feed material packing in between spaces in between his cheek teeth causing severe periodontal disease, which you can see in the photos. The periodontal disease had caused significant bone loss of his cheek teeth. In the radiographs posted, the red marks where the bone should be, while the yellow marks where the bone actually is.
As we have mentioned before, periodontal disease is a painful condition. Between the smoothness of the cheek teeth and the painful periodontal disease, these are certainly contributing factors to this horse’s inability to properly digest his food and gain weight. This periodontal disease had also caused a tooth infection which was now causing his sinus infection. When periodontal disease has advanced to this point, the only course of treatment are extractions.
The extraction of the diseased teeth along with diet modifications will allow this horse to be more comfortable and regain weight. If your senior horse is looking thin, don’t say “Oh, it is just old age.” Instead, have your veterinarian out to do some investigating.
