Take action:
Never leave pets alone with toddlers; if your baby is crawling, hold your dog in a sit/stay position; train your toddler to respect pets from an early age; teach your child not to disturb the pet while it's eating or playing with toys; children should also not insist on running after the pet when it's trying to avoid them; and remember that every pet has limits to its tolerance, even the kindest ones.
Pets vs. toddlers
Toddlers can hurt pets badly, and vice versa. So, it's up to parents to control this potentially destructive situation.
