Our friend Llyr has his own blog now, which you can find at Llyr's Blog
I encourage anyone with a corgi or other dog with DM to start a blog. If you aren't a writer, do it with pictures. It is a nice record to have, it helps educate others, and it helps the owner to see the changes in her own dog as time goes by, something that is harder to do on a day to day basis. Millie Williams suggested it to me soon after Merlin's diagnosis and now I am grateful to have kept it.
