If a horse is hot then it's pores are open, and indeed more likely to absorb fly spray than if it's cold. It is for this reason that fancy-pants cosmetics sell you a toner to apply before using moisturiser - to close the pores after a hot shower before you clog them up with moisturiser. Anyway - I digress
Absorbing the fly spray into the pores isn't necessarily a problem per se, but is probably not the best thing for a horses comfort and welfare. It might sting a bit!
why would you give your horse a hot bath?most people give them a bath after a long hard ride to cool them down.It doesnt sting them at all,that would ahve to be on a warning label and it isnt.
