Why the dogs ability to sit and roll over on command is an instinct?

The ability of dogs to sit and roll over on command is not an instinct. It is a learned behavior, trained through classical and operant conditioning.

Here's why:

* Instinct is an innate, unlearned behavior pattern that is present from birth and often triggered by specific stimuli.

* Sitting and rolling over are complex movements that require coordination and understanding of commands. These actions are not naturally occurring in dogs.

* Training: Dogs learn these behaviors through repeated exposure to cues (verbal commands and hand signals) and reinforcement (rewards for correct actions). This process involves classical conditioning (associating a cue with a behavior) and operant conditioning (rewarding desired behaviors to increase their frequency).

In summary, a dog's ability to sit and roll over on command is a result of training and learning, not instinct.
