Back in March of this year a painting was featured on here and nobody was really sure of the breed but it could have been a Glen of Imaal Terrier. There has been another one sent for the opinion of people looking on here. Have to say what a fabulous photograph it is but is it a Glen?

Just look at those eyes-of course it is a Glen
Looks glenny to me 🙂
