"I know some K9s have issues with typewriter biting"
I bet there are readers who will be confused by that because they don't know what a typewriter is or just don't get what is meant by "typewriter biting." As such, I will provide context to those few.
A typewriter is a device use to type up documents like you would do in Microsoft Word. The difference is that a typewriter uses paper and ink like a printer and prints the document as you're typing.
As for how biting can be like a typewriter, typewriters have a siding mechanism that moves the paper in the direction opposite to the way your language is written (left for left to right and right for right to left). The typewriter types by striking the paper with hammers covered in ink to leave its mark. So from that context, typewriter biting is what happens when an animal rapidly bites and releases over and over while the bitten area moves back and forward.
