My horses require trimming every 4 weeks this summer. Usually by the end of 3 week after the trim they have splits on the very end of wall. Nothing very bad, but still doesn't look great. Nothing in trimming was changed since last year. However the weather is EXTREMELY dry this year. I think that can be a case. I know some people use that "rain maker" and some says it's better not to use. Does anyone have same problems with hoofs? Any solutions?
