There will always be a point at which the vessels feel full, big and toned - in other words, when the vessel anatomy takes over and it is not just vasotone mediating the force and compressibility of the pulse. The femoral artery is close enough to the aorta that I would expect it to be one of these locations.
That's why I encourage (for example, in horses) finding a distal pulse like at the coronary band, the face or the underside of the tail to do your pulse diagnosis, rather than the carotid, as Qi grads are taught. Moderating the pulse at the coronary band would likely not produce much change at the carotid.
If you were able to change the distal pulse in these dogs and the points that did so make sense given what is going on, then I'd say what you were feeling distally was real, regardless what the more proximal portion of the femoral felt like
