Hi everyone,

I have a 3-year-old Border Collie. She's incredibly smart and knows a lot of commands—we've done plenty of training together.

The only issue is that she becomes extremely aggressive toward other dogs, but only when she's with me or my husband.

If she's with someone else, she's perfectly fine around other dogs.

She knows all of her commands, but once she sees another dog while she's with us, it's like nothing else matters. If she's off leash, she'll run over and try to bite. She's never aggressive toward people—only other dogs.

Our trainer thinks she's being protective of us, but I'm really worried that one day something serious will happen.

Has anyone dealt with something similar or have any advice?

Finally got my hands on a HEAD Gravity. First thing — the design is stunning, easily the best-looking frame I've owned.

The good: power is insane when you catch the ball center. Shots land deeper than usual without extra effort.

The bad: miss center even slightly and it goes straight into the elbow and wrist. No mercy.

The weird part: this is the first racket I've ever owned that whistles on the takeback. Full audible whistle. My hitting partner thought I was messing with him. I wasn't.

Anyone else running the Gravity with solinco mach 10? Curious if the off-center harshness is normal or a string tension thing.
