So, my girl (27kg greyhound/collie/husky Cross) has 2 staples in her chest and a big bruise above the wound after playing with our friend's 7mth old collie pup all day on Sunday.
They are good pals, but the play is usually tumbling and chasing. They were in the garden with us all day whilst we were bbqing etc and noone noticed anything unusual, and certainly no yelps or growls from either of them.
The play is usually a chasing game, but can be wrestling and some mouthing - usually ears and jowls. Clearly it went too far at some point, as we all suspect the pup has bitten her.
How do we change the play? Re directing? The pup is ball obsessed, so I'm loathe to use a ball to distract her - I've also noticed she's getting protective over tennis balls, so it's possible the bite was down to that?
They're never unsupervised, but our dog is so stoic she rarely makes a noise - barely a squeak and a wriggle when she was stapled, poor love - so if it does go too far, they are not showing it.
