How to differentiate single coat and double coat German Shepherd? This undercoat works as a fantastic insulating coat, and during the winter months, the undercoat tends to get thicker. This, coupled with the second coat, makes double-coated dogs especially well-suited to all types of weather. Single-coated dogs, on the other hand, only have an external, protective coat. #CameraBaba #doggo #germanshepherdofinstagram #germanshepherdworld #gsdnation #dogtraining #sch #cute #husky #gsddaily #instagr
