Calvin Coolidge also had two other collies while in the white house. Bessie a “yellow” collie (we now call this sable) and Ruby Rough a brown collie (which would be a mahogany sable). Try as I may I have not been able to find any pictures of these two collies. Seems they were outshone by their two white family members.
The first mention of a Collie in the White House was of Benjamin Harrison’s Dash. Below is his picture. I think he was probably a half-breed collie, but he does have collie in him by the looks of him.
In the 1890’s Dash was at the White House….
After the Coolidges had their collies Herbert Hoover then took over with several dogs including a collie named Glen. I have found no pics of Glen but here is Herbert Hoover with his most famous dog, King Tut.
Next came Johnson in the 1960’s with his white collie named Blanco. As far as I know unlike his hounds Johnson never picked his collie up by the ears. Johnson should’ve had other ppl name his dogs… after all Him and Her, big beagle and little beagle are not great names but to each their own I guess. Below is a picture of Johnson with his White Collie, Blanco;
Thats it for collies in the White House. Hopefully our next President will have a collie.
