Thanks, this has eased my mind :) Things have settled down a lot today. They were in the yard for most of the day and both had good rests/sleep. Marlu (my kelpie) had his final injection today, not sure if like humans it can affect the dog, but today was a better day. I appreciate your reply and Marlu loves the training. He sits, drops, targets, takes his rewards so gently and is slowly coming around to the leash.
