So sorry to hear about the loss of your cherished boy. He was a great ambassador for the breed and showed that the " Black Ones " could more than hold their own against what many considered  to be  the " flashier " Tervueren at the time all varieties were shown together. Some Groenendael breeders at that time either gave up or would not show their dogs but Felix showed time and again that colour made no difference to a beautiful dog. He was a once in a life time dog and I know Vic and Lyn considered him to be the best they had ever bred and I am sure they are also feeling very sad at his passing. I am sure you have many wonderful memories of your time with him which will, as the sadness fades, make you smile when you think of  them..  Take care.........Lynda McNamara (Kehala, UK)
