Such assumptions beagle....see note to PF earlier! Debate is the forum, argument is the constructed communication involved in the forum Strangely though we actually agree...this horse indeed needs to see a vet...my main claim...probably not you though as whilst not a couch but I do guess you might be seated in a chair! Princeton, a hoof abscess is an infection. It causes destruction of tissue in it's localization...hence you see the hole in this horse's hoof. An infection can spread to involve other structures deeper in the hoof. One of the concerns is the pedal bone...a very porous bone in the horses foot. If an infection gets into the pedal bone if infection gets into this structure you can have destruction of the bone....anyway I could go on but this is one of the reasons xrays are required to check for evidence of further destruction. It helps with diagnosis and treatment options.
