Well three now!! My mare who I've had for 9 years, her colt foal born this year and a companion foal I've just bought for him! Can't believe I've gone from one to three horses in a year!!
None. I "handed over the reins" of my second horse to my mum last week. So although I get to help with her (and still have to help pay some costs), she is officially no longer my horse. I am horseless
Give it five years or so and I may have my third horse!
