My dog has played zoomies with a large lab. I wasn't too worried about my dog - she's very good these days at not crashing into things but she will use obstacles (people and dogs and furniture) to dodge around to get the advantage on the other dog. And the other dog - not being as agile - will crash into the obstacles.American staffy that was running around and having a great time playing. I was standing up against the bench/seat and he wasn't watching where he was going and slammed right into my leg at full force.
This big lab - wiped out his own owner - bowled her legs straight out from under her and she fell on top of him so they were both hurt and took a while to get up. I was mortified. And now I won't let Frosty keep playing if she uses people for slalom obstacles. And I won't let her keep playing if she skittles other dogs either - no matter how much the other dog might want to.
The chance of injuring dogs and people is just too high.
Dogs get their joints dislocated and tendons broken and so do people. I know people who have been crash tackled by dogs - getting their knees and legs and wrists broken because of it and it's really hard to get the person responsible (owner of dog doing the crash tackle) to pay for the damage they cause.
First you have to identify them and then you have to prove it was their dog and the damage was caused by their dog... and they just nick off and leave you with the medical and vet bills to pay.
Strangely this kind of injury is not considered as severe as bites but joint injuries can be far more debilitating.
So KM - you really have to watch out for zooming dogs, they will crash tackle.
If you had jumped out the way - that Amstaff would have broken its shoulder on the bench and you wouldn't be having to deal with the owner trying to blame you for your injury.
I do find yelling and making noise as dogs approach - often causes them to pay more attention to where they are going. But doesn't guarantee they won't crash into you. Never take your eyes off zooming dogs. Or the ones lying in ambush.
