I, too, ordered some ostrich and venison tendons and some trachea. Gave Freddie 1 ostrich tendon and he really enjoyed it. Was planning on only giving him one if/when he got over excited in the early evening, which does happen now and then (humping, attention barking and generally wandering about looking for mischief even after games and training sessions!). However, we went out for a meal last night, were gone about 2 and a half hours, and he managed to get in the cupboard under the stairs in the kitchen (which has a hook and eye to keep it closed but the eye sometimes comes out of the door!). We came back to discover he had eaten the WHOLE packet of ostrich tendons! He hasn't been sick today but has been acting a bit oddly and has been farting for England!
