-2.26 lb

Step-by-step explanation:

Let the dog's initial weight be d.

Then, one year later, the dog weighs 3.73 lb less, and thus weighed d - 3.73 lb.  

During the next year, the dog gained 1.47 lb, so now weighs d - 3.73 + 1.47 lb, or

d - 2.26 lb.  This indicates a total weight loss of 2.26 over these two years.
