Sure, let's break this down step by step:

1. Independent Variable:
The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable. In this scenario, the independent variable is the type of dog food given (new dog food vs. normal diet).

2. Dependent Variable:
The dependent variable is the factor that is being measured or tested in an experiment. In this case, the dependent variable is the weight loss of the dogs after one month.

3. Experimental Group:
The experimental group includes the subjects in an experiment that are exposed to the variable under investigation. Here, the experimental group is the group of 50 dogs that are given the new dog food.

4. Control Group:
The control group includes the subjects in an experiment that are not exposed to the variable being tested and are used as a benchmark to measure how the other tested subjects do. In this scenario, the control group is the group of 50 dogs that continue their normal diets.

So, summarizing the scenario with their corresponding groups:

- Independent Variable: Type of dog food (new dog food vs. normal diet) - [tex]\( 14 \)[/tex]
- Dependent Variable: Weight loss of the dogs after one month - [tex]\( 15 \)[/tex]
- Experimental Group: 50 dogs that are given the new dog food - [tex]\( 16 \)[/tex]
- Control Group: 50 dogs that continue their normal diets - [tex]\( 17 \)[/tex]

Using the provided numerical values:

- Independent Variable: 14.
- Dependent Variable: 15.
- Experimental Group: 16.
- Control Group: 17.
