Nasty cut, so glad its not worse as you said, it could have been. Foot injuries usually heal fairly quickly in horses, thank goodness! Keeping clean and sanitized is the toughest part, since its not worse. That's exciting about your daughter; perhaps she will become a wonderful vet. The world certainly needs more of those!!!
"If you talk to the animals they will talk with you and you will know each other. If you do not talk to them you will not know them and what you do not know, you will fear. What one fears, one destroys." - Chief Dan George
