My 2 year old pup currently has the same 'horn'. Grew so fast. Vet sent me to veterinarian surgeon who wants to amputate part of her digit to remove it. He says otherwise it will grow back. Wondering what you did and if it worked. Thanks. ShelleyI recently discover a black nail like horn on my dog's paw pad which is called cutaneous horn it growed so fast that i just can't believe myself how i couldn't notiece it until know anyone else's dog suffered this ? How dangerous can it be ?
