I couldn't help but think about the heat loss with wet hooves andThat's OK. We're used to you!
Absolutely right that cold and wet is worse than just cold. Heat is
transferred to water very easily.
Hoof perfusion does change with temperature too. Blood is shunted
away from the periphery when it's cold by opening arteriovenous
shunts inside the hoof. Angela had her vet do a thermographic study
of two of her horses 2 winters ago. Compared to a horse with a less
extensive laminitis history, under the same conditions they found a
dramatic drop in her hoof temperatures after 20 minutes in a 40
degree room without her feet being bundled up.
