Hi Skip, Thank you for contacting "ask extension" with your question on ground cover. I'm going to send you links to a lot of information. I'm attaching an article which discusses two native grasses that are good for erosion control. Both are types of wild rye. ("Arlington" and "Elkton"). You could plant the grass now and then changeover to something else next year. https://today.oregonstate.edu/archives/1997/oct/native-grasses-tapped-revegetation-erosion-control
Other good options for ground cover would be Coastal Strawberry (Fragaria chilioensis) and Kinnikinnick (Arctostaphylos uva-ursi). https://extension.oregonstate.edu/news/native-groundcovers-are-great-home-landscapes
Here is a link with pictures of more ground covers you could use: http://www.pnwplants.wsu.edu/Groundcovers.aspx
And if you would like to use shrubs instead, here is a list of trees and shrubs for erosion control: https://extension.oregonstate.edu/collection/trees-shrubs-erosion-control
There is a lot of material here! Let me know if you would like help narrowing down your options.
Love your dog!
