Saw this mini donkey the other day. Had a bulge on the dorsal wall at the coronet band. Wasn't sure what was going on til I started a little exploration. Looks like white line, although I have never seen it bulge out at the top like this before.....

Any comments guys.....
Before exploration





after some exploration

The top photo may be from a "GRAVEL", would have to see the bottom of the hoof/sole area. When the bottom of the foot isd cleaned off the Whiteline will a definite BLACK coloration. If an oxadization agent such as "CLOROX BLEACH" is applied full strength there will be a "FUZZING ACTION" like putting Peroxide on a cut! If it does fuzz then there is definite Thrush and if on the White Line area then it is WLD. In its more advanced stages then there may be much Hoof Loss especially if it goes untreated! "WHITE LIGHTNING" is the best (not the drink) or any Thrush treatment that says it is good on WLD!!

White Line Disease is when the Lamini of the White Line is eaten away by a more stronger fungus but the same as is present in Thrush and starts much the same way-just more potent!! This usually occurs from the bottom and works its way up until stopped or until there is nothing to feed upon! And like THRUSH it cannot live in an Oxygenated environment! Clorox Bleach is good to tell if it is the same Fungus but will not do a good job as far as treatment goes!

Rick, thanks for your info.....Yeh, I believe it to be whiteline. The wall distal to the bump at the coronet, was separated all the way down to the ground surface, from the corium layer underneath.

You know, I'll bet that special "white lightening", known to be brewed in the south, just might kill more bugs than one might think.....

Could be both, a GRAVEL and WHITE LINE DISEASE. The WHITE LIGHTNING was purchased from a magazine COUNTRY MEDICINE-we receive this through the mail, but mainly any THRUSH medicine will work if on the label it states that it is capable of treating WLD! In this case I'd do it anyway not necessarily for this hoof because it may be "DEAD" anyway but to stop the disease so that good healthy hoof can replace it-then I'd teach the owner how to clean a hoof so that it doesn't happen again!
