If Fern is a " woolie " no striping/grooming will change that - she will need to be clipped every so often . Otherwise handstripping (no knives/blades anything sharp/cutting involved !!! ) can improve a dogs coat to a degree - did this only with my terriers , for whom this is the normal way of grooming . Never stripped anything else but the ears of a deerhound , too much work and , for my girls , luckily not necessary - let alone , that deerhounds are not supposed to be stripped . Also , spaying/neutering can affect the texture of the coat , make ist softer , more profuse
Perhaps you can check with her breeder what best to do?
