The more stress, the more likely someone or somedog is likely to "react". For mom, that would be swatting, for the dog that would be biting, the toddler acting out.
Emphasis should be placed on managing the situation to reduce stress. Tie the dog in a safe spot with a bed and chew toy. Put the toddler in a "play pen" with suitable toys. Then mom can have a break to cook supper with just a small amount of supervision rather than doing damage control.

She needs to set EVERYONE (including herself) up to succeed in the
cooking-dinner situation. What she's got now is a recipe for disaster.
Do what Pat does--make it so that both the kid and the dog can be praised
for exhibiting the desired behavior. Then, the mom is working to create
that behavior as the normal for her home.
Plus, the mom doesn't lose her cool and also her credibility as the worthy
leader of the group of beings.
