More recent evidence proves that the major contribution to the smell of flatus comes from a combination of volatile sulphur compounds (vsc).[5][12] it is known that hydrogen sulphide (h2s), methyl mercaptan, mm (also known as methanethiol, mt), dimethyl sulphide (dms), dimethyl disulphide (dmds) and dimethyl trisulphide (dmts) are present and cause the smell.Those compounds are the one percent that cause the smell.
Symptoms include a whitening of the lens, which is a clear part of the eye needed for focussing, and the problem impairs sight and may even lead to blindness. The whitening or cloudiness is opaque and thus cannot be seen through. Inherited cataracts can occur at any age in the affected dog.
But there isnât just one cause for cloudy eyes, and you should make sure that you see your veterinarian to confirm that your dog is just experiencing the normal aging process. Just because your dog has cloudy eyes, doesnât mean it canât see and even if it canât see, doesnât mean that your dog isnât happy! Blind dogs adjust well to their environment and function very well. The next time you take your elderly dog to the veterinarian, make sure you discuss its eyes.
