Below is a PS to a letter I wrote not long ago. I think I was frustrated at the time, and though I do not hold it against them, they really are perhaps the least swift dogs I have ever dealt with. (Swift is Not meant to be a comparison to Grey Hounds in this case.)
PS. I am also sending some pics of the most stupid dogs in all of everything there is or ever was or ever will be. We installed a dog door more than a month ago and these two dogs, are just now starting to go through the door by themselves. I thought, its not their fault, poor little things have no room for much of a brain in their little melons. I had spent hours doing everything from very nicely coxing them and bribing them with all manor of treats to gently stuffing them in head first and ramming them through with the butt of my hand like a man ramming the powder and ball down a muzzle loader, lol. There are two clear rubber flaps that hang down so things don't blow back and forth and your AC doesn't have to cool all of creation. They would go through after a while if I pinned these flaps up, but no way if they had to push through them by themselves. I really did think they were the stupidest dogs ever, but than i looked at them one day, and realized it is genetic. Somewhere in their past their distant relatives must have run head first into something very hard. This is how they got the flat faces, and now by instinct they will not push their faces up against anything. it is the only answer. or if not that, they are about as smart as a polished rock. Which is about how much room they have in that little tiny flat faced head for a brain.
