Will our client’s dog [name withheld] and his heart condition, benefit from a Protocol session?

This is the case. It is not that a total cure is readily achieved in this way, but there are things that can be done to reduce the severity of symptoms and in particular, to avoid a further downward spiral and that is the next best thing. Much will depend on the animal's own response to the shift in energy and experiences and to what extent it feeds the problem with negativity in its efforts to help the owner. For animal healers, this is the greatest pitfall, that in taking on the energy of discord from the loved ones, it will be added to existing misalignments because it is a match vibrationally, and they inadvertently worsen their own weakest link. So this is not the best way to heal, but a trap many animal healers fall into because they are going by instinct essentially, and the energies have a life of their own without more direct oversight and guidance, which would be the case were the conscious self making deliberate decisions and choices on what to do about each circumstance being addressed. Left on their own, and to their own devices, animal healers will take the path of least resistance by internalizing everything and then adding it to their own energy in a way that, in effect, it truly becomes their own problem to deal with and that will exacerbate current issues. A healing outreach from you would have material benefit.
