I say this all there time and it goes in one ear and out the other.
Knowledge sharing post No.1.
Digital/Phalangeal Alignment in a wet environment.
Pollitt and Hampson did a study at University of Queensland a couple of years ago.
They concluded the hoof wall has a constant moisture content. The sole however is like a sponge, soaking up all available moisture .
When hydrated to capacity, it loses it's tensile strength and the ability to support the hoof capsule as intended.
The back third of the hoof, which is also the shock absorbing section, drops or prolapses as a result. Counter rotation of the coffin bone occurs.
This is now known as negative palmer/planter angle. That is the angle the bottom of P3 makes in relation to the ground.
As a farrier, the best results to help this are to engage the back third in a load sharing package. Traditionally a heartbar shoe or wide bar was used. More recently dental impression material or pour in material is added to load share with frogs and commisures.
Plastic frog support pads are available most recently, as skills to fit a heartbar correctly are highest level. Protecting the internal structure are paramount whilst load sharing.
Horse's hooves are not designed to be constantly wet. Best results are to remove the cause.
A dry bedding of pine sawdust draws moisture and helps kill bacterial invasion of the whiteline and/frog's.
Overloading of the over hydrated hoof is exacerbated by the weight of the horse. To many horse's are overweight for the tensile strength of the hoof capsule.
If your horse gets to the situation where it needs this specific shoeing package, it's your responsibility as an owner to change the management or husbandry process.
Horse's shod with a load sharing package should be in a confined environment where they can't gallop about with the possibility of overreaching causing premature shoe loss. They should not be in a herd environment where other horse's can stand on the shoe's at play causing premature shoe loss.
Your farrier sees your horse at a cyclic time to reshoe, trimming the hoof to keep in balance perimeters.
The management between visits falls squarely on the owner.
Unfortunately to often expectations of correct digital alignment are overshadowed by owner mismanagement. I'm older and get grumpy when "buck passing " ends up in my lap.
At the end of the day as a professional tradesperson, it's me who decides if I continue to be trying my best for your horse's welfare 🙏
