Yes John ...it,is prob all due to the season. dogwoods do lose their leaves now to show off those red srems.
I would just assume your dogwood is fine and take some hardwood cuttings .....either in pots or in the ground. I find they root very easily and form a decent shrub in 2 years.
out of interest what weed killer did you use? If it was glyphosate it will have no affect at this time of year.
