These are exactly what we use when running dogs in harness on the type of ground that maybe uncomfortable on their feet
Having been for a visit to his yard with friend for her to do photos for his website and waiting 20 mins for him to come out his house due to his mums words "he's rather shy" but when it comes to his business and his horses I guess he isn't
Whenever I have met him he has always seemed very shy and polite, watching him school a horse is fantastic he never pushes too hard and quite quickly picks up their strengths and weaknesses
A friend of mine had a double hip replacement on her malamute boy done by Noel (before the TV stuff came about) and he recovered exceptionally well and has a great quality of life doing all the things her other malamutes do which he didn't get to do before
And it was, fantastic Sally and Ali are some of the most experienced sibe owners/workers/breeders in this country I've always coverted one of their dogs lol
Oh what a little sweetheart she looks and sounds.
It sounds like your doing everything right and I bet she will love being able to go up to the yard with you in future
P.S more pics please
