SUMMARY: Boost resorts to body bashing, for everything.
Knowledgeable folks have observed that Boost isn't even trying to avoid knocking bars. I am, at times, at my wits' end when doing bar-knocking drills, trying to get even one single jump that she doesn't touch at all on her way over.
Tika seems different: She usually hits them on the first bar, on a difficult turn, or when I do something wacky on course. But Boost--jeez, they just go flying!
I don't know why it surprises me. She thwangs through the doggie door flap like it's an enemy phalanx and has ripped it out of its frame and torn it into pieces as she blasts through. It's a challenge to keep it taped together (at $60 a flap, we're not replacing it every time she rips it).
She hits doors on her way through. I have had to reseat my sliding screen doors dozens of times, with tremendous fuming and cursing and breaking of fingernails. My bedroom has a double door, and she hits the 2nd door every time, rattling it like crazy, which is particularly bad at 2 a.m. and other people in the house might be sleeping.
She whacks into me when she thinks she's in a particular hurry. I sometimes fear for my life when she hits me going down stairs. I've been trying to grab her when she hits my legs to tell her to cut it out, but--well--when Boost's in a particular hurry, by the time I realize what she's doing--or done--she's 10 feet ahead of me already.
She deliberately smacks into Tika when Tika is running and chasing the fetch toy, although that always strikes me as herding behavior because she comes in from the front, not the side.
In short, she doesn't care what she hits with her body. So it should be no surprise that we have a problem with jump bars.
