is that terriers hpr or gundogs? reason i ask is i do the same with gundogs ( a lite meal before work and the main after) but when i had terriers i fed at night ,my reasoning gundogs are on the go all day and need a steady release of energy but terriers work in generally shorter burst ,unless on a long dig Both its just something I've always done . I've dug with lots of other people and none of them do it . You never know how long your dogs going to be to ground or how many dogs there going to have in the day . So if it's done you know there right for any occasion . Jmo .
