Blind rage

OK, so maybe I should have anticipated this.
While we were at work Monday, a "stump jumper" came to our house to remove some woody old azaelas that have become magnets for invasive weeds. These azaelas are located on the side of our house.
Because it's so narrow there, the stump jumper was unable to use his equipment; he had to remove them manually. This cost extra. On the upside, we figured, the process would be quieter, and wouldn't unsettle Zorro.
Wrong.
Late Monday, I discovered that the lower slats of blind over the window in the guest bedroom--which looks out over that section of the yard--was covered with teeth marks and gashes. Pieces of the blind were on the floor. (note: this is not a cheap blind).
Denny called the stump jumper, who said Zorro was highly agitated by the axe he used to remove the azaelas. Every time he swung the axe, he could hear Zorro raging on the other side of the window and said he feared he would come right through the screen. He said he felt sorry for Zorro--he's the owner of a rescue lab, which speaks to both to his character and common sense--and tried to calm him from the outside, but was unsuccessful.
So now the cost of our stump removal has gone up by $150. Off to the vet today for blood tests.
