To determine which change in weight is greater, we need to compare the absolute values of the changes.
The dog's weight changed by -7 ounces while he was sick.
To find the absolute value, we disregard the negative sign. So, the absolute change in weight is 7 ounces.
Now, we compare this with the other option you haven't provided. Once you give me the other option, I can calculate the absolute change and determine which is greater.
