I'd like to add some more hill work in, but we've honestly not had time!
I'd be curious what kind of massages you learned--that wasn't part of any of our rehab schedule.
Hill work is so easy. There's a nearby park that has a great grass-covered bowl. I stand at either the top or the bottom of the bowl and toss the frisbee or ball, up or down. Phebe loves it.
Massage is very simple. I use a pad that you heat in the microwave. I got mine at Walgreens. It's filled with clay that retains heat (or cold) and has a cloth cover.
With Phebe laying on her side, I place the pad on her shoulder for 3-5 minutes. Then, I start at the top of her shoulder and massage with a kneading motion all the way to the tips of her toes and back up again. You don't need to try for deep tissue massage, but it is important to go down and then up to help move any waste material in the muscles back toward the lymph system, since the lymph system is gravity driven. After the massage, then we do passive range of motion with that leg -- support the elbow or knee, flex and hold for 5 count, extend and hold for 5 count (10 reps).
While I'm massaging her shoulder I put the pad on her hip and rear leg, and then massage that area. I also do some light massage of the iliopsoas (groin) muscle after I've warmed that area, I put the pad on the iliopsoas while I'm massaging the hip and rear leg. Flip her to the other side and do the same. Then, I stand her up and massage her spine by placing my thumbs on either side of her back bone and massaging in small circles. I usually start at the neck and work my way to her tail.
After the massage, we do some nose to rear foot stretches, 5 reps each side (use a treat), and some cross leg stretches front and rear, 5 reps each foot.
I do feel fortunate to train at a place that offers conditioning classes. They've also had a PT vet give workshops on physiology and massage. Maybe if you asked your instructors they might consider doing something like that. The PT vet we use has a non-profit foundation that helps dogs who need major surgery and rehab, so we did the seminar as fundraiser for the foundation. I think we paid $25 to attend a 2 hour session.
