She is cute! you are right she will not be able be a trail dog until fully developed, but you can and should start her training now before she becomes independent. You must become the centre of her world and then she will do anything. Do not be harsh with her and always reward her when she does it right ie. lots of praise and treats. Start with her normal feeds, put the bowl on the floor and make her WAIT till you say go. She will soon learn. You now have a dog that will wait when out on the trail. Similarly when you open the car door make her wait to get out. Recal is another necessary one, when she comes to you reward her with lots of praise and a treat, but make sure she comes all the way to you not six feet away, do not go to her, remember you are in charge. Animals are very good at giving you just enough to keep you happy, you must insist on 100%, then a reward.
My whippet/pointer is a trail dog and is usually ahead of me but always keeps an aye on me. I use a whistle attached to my camelback, 1 beep to stop,2 beeps to recal.
Sorry to go on but love riding with my dog .I will post a picture when I work out how.
