Answer 1

The correct interpretation of the conditional mood in the sentence "If my dog is feeling better, I could take her for a walk" is:

it expresses uncertainty that the dog will be walked due to its sickness.

The use of "could" indicates a possibility that depends on the condition of the dog feeling better. If the dog does not feel better, then the speaker may not take her for a walk.
