To find the correct equation, we need to determine the change in height of Ada's dog from when it was a puppy to its current height.

Given:
- Height of the puppy: $$5 \frac{1}{2}$$ inches
- Current height of the dog: $$14 \frac{1}{2}$$ inches

Let's denote the change in height as $$x$$.

The equation representing the change in height can be written as:
$$ \text{Current height} = \text{Puppy height} + \text{Change in height} $$

Substitute the given values into the equation:
$$ 14 \frac{1}{2} = 5 \frac{1}{2} + x $$

Now, we can solve for $$x$$ to find the change in height.
Solve the equation by following steps:
- step0: Solve for $$x$$:
  $$14\frac{1}{2}=5\frac{1}{2}+x$$
- step1: Convert the expressions:
  $$\frac{29}{2}=\frac{11}{2}+x$$
- step2: Swap the sides:
  $$\frac{11}{2}+x=\frac{29}{2}$$
- step3: Move the constant to the right side:
  $$x=\frac{29}{2}-\frac{11}{2}$$
- step4: Subtract the numbers:
  $$x=9$$
The change in height of Ada's dog from when it was a puppy to its current height is $$9$$ inches.
The change in height is 9 inches.
