My Pyr had his dew claws, never a problem and my lab mix has a double back dew claw on one foot and dew claw on the other and never a problem with him either.Both dogs were rescue allthough the pyr we knew the breeder and was already neutered,the lab mix we neutered but as no problems were occuring we decided with our vet why bother and to this day I trim all the dogs nails regularly and there are no problems.The dew claws do grow a bit faster as they don't wear down any but why put them through any discomfort unless it is necessary.None of the others have dewclaws..If the nails are long now do have the vet cut them while she is under and then cut them very frequently and keep them short and little by little you will get them cut back.Plus they get used to it with you playing with their feet alot and I use treats on some of the dogs/some I don't but lots of love and I take my time but it usually only takes a few minutes.
