How do I add names only in the Name column of the table?

Question

I'm creating a dog top trumps style game using tkinter and need it too display names only in the Name column but it instead spreads the names across all columns

labelText.set("These are your cards")
tree = ttk.Treeview(root,columns=("Name","Exercise","Intelligence","Friendliness","Drool"))
tree["show"]= "headings"
namecol = tree.heading("Name", text="Name")
tree.heading("Exercise", text="Exercise")
tree.heading("Intelligence", text="Intelligence")
tree.heading("Friendliness", text="Friendliness")
tree.heading("Drool", text="Drool")

tree.grid(row=6,column=0,columnspan=5)

lbl = tkinter.Label(root, text="Your Cards")
lbl.grid(column=0, row=5, columnspan=5)


#creates a list with each dog in it
dogs = []

with open("dogs.txt", "rt") as in_file:
    for dog in in_file:
        dogs.append(dog)


for value in dogs:
    tree.insert("", "0", value=dogs)

I end with it displaying the text file over all columns instead of to the name column, instead of it only displaying in names
