Lately I have noticed a change in the way my yearling Alpine is standing. Her rear hooves are growing almost sideways inward towards each other and not straight to the ground. This has caused her rear hooves to look like they "toe in" especially in the morning before she gets milked and her udder is full, which makes her rear legs spread apart and looks uncomfortable. her hooves are trimmed every few weeks and her last Bose shot was in March. Oh, she has also had a copper bolus given last month. Does this sound like something that Bose would fix or genetic? Her feet were perfect prior to this.
