Oh, I didn't realize he was in such soft ground - sorry! No, he doesn't need water then. My horses are on 24/7 365 days a year turnount, so I have to get my horses hooves access to water everyday, just imagine what your fingernails would be like if they received no moisture....
I don't know what diet your horse is on, but you might be able to supplement him to help him harden his hooves. I just finished an interesting book - "Healing Horses - Their Way" and have actually contacted the author on a few things. I am sure she would help you find something natural to help out. This is the website - www.rivasremedies.com
- she is from British Columbia.
It is good to hear that you are taking your guys out onto hard ground everyday - movement will definitely help the healing process. Keep that circulation going and help the blood stream take out any toxins that may be stored under those under run heels.
I am totally impressed with this thread, lots of info! Keep us posted!
