I agree rear dewclaws are the ones most likely to cause problems.
They can vary from proper toes to skin tags with just a claw.
We don't get them in our breed, but I fostered an Elkhound Husky crossbreed of around 18 months.
On homing with her new owner he hadn't got his Insurance set up before she tore one and needed surgery, he could have kicked himself not getting the Insurance in time.
Traumatised one took longer to heal than the one removed at same time.
Stupid thing is it's perfectly legal fro a breeder or anyone else to dewclaw a puppy before it's eyes open, yet a vet has to d tails, in situations where it's still allowed..
