I think ANY of my three dogs would have killed a fox cub. None of them are ex racers!
Killing a fox cub or a rabbit for that matter, does not mean your dog is going to eat little tiny dogs in the park.
But, do exercise some caution. Whilst a little dog sitting minding its own business may not be 'lunch' a little dog hurtling past at speed may trigger your dogs chase instincts.
I actually DONT like exercising greyhounds/tall pointy dogs in muzzles for two very good reasons.
1/ Most of them WILL still catch whatever they are chasing, and instead of killing it quickly, will just batter it to death with the muzzled face (the dog doesnt KNOW it cant bite with a muzzle on).
2/ Many lurchers/greyhounds will attempt to remove the muzzle whilst they are running, which in a smaller, shorter legged dog might not be a problem -- in a long tall greyhound that can = broken neck/leg/back.
Use caution and common sense, and LEARN your dog first before letting him off in an area with lots of little dogs.
My saluki x grey is safe around little dogs now. She worked up until last year, killing basically anything her previous owner pointed her at, including cats!!! She is EVEN safe around MY cat, EVEN outside (although i dont ike her playing wth him!), however other peoples cats are still fair game for her.
She has not once injured any other pet animal and with me has only killed squirrels (at my request) and the odd rabbit -- and she has had 9 years of zooming around killing anything that moves!
It can be done iwth patience and time.
