It's hard to believe he have never had any vaccines. He needs to be protected from the flu, West Nile, and the rest. Not sure what England requirements in the way of shots. He will really need them as he get older and his immune system weakens.
Does this horse hold any conformation problems you can see?   How much will my legs sway down on a 14.2?   What is that call? 10 pts best answer?   Arabian Hunters and Sporthorse Under Saddle..?
