A Healthy Puppy Should Be Clear-Eyed, Somewhat Roly-Poly, Loose-Skinned, Free From Any Skin Trouble, Hungry For Its Meals, And Lively. It Should Not Be Timid Or Shy. If The Puppy Seems Warm Or Sleepy Most Of The Time, Ask One Of Your Parents To Take Its Temperature. Pulling On The Leash Is One Of The Most Common Mis-Behaviors Seen On All Kinds Of Dogs. Puppies And Adult Dogs Alike Can Often Be Seen Taking Their Owners For Walks, Instead Of The Other Way Around. Pulling On The Leash Can Be Much More Than An Annoying Habit.
