What about using dew claw protectors for when she plays ball? I have a friend who asked the same thing a while back and one of my other friends recommended these:

As far as I know, the removal of bony dew claws can be quite nasty to heal. If she's wrecking them often it might be in her best interest but I think I would go down the vet wrap/protector type route before considering removal. Rear dewclaws are regularly removed from young pups in the first few days of life, this is definitely different to removal as an adult.
What a nuisance for you both though, hope you manage to sort it whatever you do :)
