Yes, I've had a houseful of Rotties for years, and used to be a member at DITH. You seemed familiar, but nothing I could put my finger on. Grizz-Bang is probably a one of a kind name.
The only two dogs I have from that time are him and Libby. I've lost the others, Rom and DeeOhGee to bone cancer. Rom 4 months after he earned OTCH. I've had a rough couple of years.
Good to see you here!
