    There are a couple factors at work in the differences you are seeing. 1 is the fact that blooms are set in late summer/early fall; therefore, pruning in winter removes blooms. However, it is easier to see the structure of the limbs when leaves are off which helps in determining which to remove. Insects are dormant in winter and borers are a potential problem with summer cuts. Lastly, pruning wounds heal fastest in early spring as growth begins which limits exposure to disease and insects. Summer blooming is sometimes done right after blooming. Wounds may bleed sap at this time of year although I've recently read that this isn't harmful to most trees. Back to the issue of disease and insects, summer cuts (wounds) are during the time of greatest exposure. It is up to you to weigh the pros and cons; personally, I would lean toward late winter/early spring pruning. However, right away is the best time to remove damaged, diseased or dead branches. The longer they remain, the greater the risk of insect and disease problems.

    What you describe is a very dire situation. The tree cannot survive extensive bark loss. The most likely reason for this is that the tree has died from lack of water. But there are other possibilities.
    You don't say if the tree still has any green foliage.
    Without photos of the tree and the site, and description of the growing conditions and history of soil and water management, we cannot determine the cause and remedy if any.

    Yes it is of grave concern. It appears that the trunk was severely wounded and now wood rot fungal infection is present in the exposed heartwood. The bark peeling from the trunk at the higher point may be another wound, or could be a fungal infection due to the impaired circulation as a result of the lower wound.

    Not much you can do but wait and see if it can overcome the wounding and infections. Provide good soil fertility and water management to enhance health and wound closure.

    Pull back the mulch to 6 inches or more from the tree trunk, so it is not piled up against the trunk keeping it too wet.

    If mine I would apply a biological fungicide as a soil drench around the base and also as a trunk drench. Now and once a month through the growing season. One of these:

    It sounds like you have red osier dogwood, also called red twig dogwood. If you are in a house that was just sold, the shrub is considered part the buyer's property if it isn't explicitly excluded in the sale document. Since the ground is probably still frozen, digging it up isn't possible. But, it is possible to take cuttings. Red osier dogwood readily roots from cuttings. Here is an article that explains the process.
