You could .pivot() your DataFrame so that Year becomes the index and SubCategory the columns, then plot it.

df = pd.DataFrame({
   "Year": [2000, 2000, 2001, 2001, 2002, 2002],
   "Pet": ["Dog", "Cat", "Dog", "Cat", "Dog", "Cat"],
   "Weight": [10, 5, 11, 6, 10, 6]})
df.pivot(index="Year", columns="Pet", values="Weight").plot.bar()

As an aside, I don't love bar plots with years along the x-axis, as I don't consider years to be a categorical variable.
