We haven't used this old television cushion chair for years, but our Lab-rotty cross found that it suits him perfectly.
We don't know why, but "Coby" prefers to put his head up onto a pillow, or pretty much anything else that will elevate his head while he sleeps. It could be a breathing thing, or perhaps he just likes to imitate the human pillow practice. He is a funny boy. We love him. Ten years old now.
