TIP #1: DON'T IGNORE (OR PUNISH) A GROWL
Growls, lip curls, stiff bodies, and hard stares are all messages from our dog that she is uncomfortable and that, if pushed much farther, a bite is imminent. Instead of ignoring or, worse yet, punishing a dog for these displays, take it seriously for what it is, a warning. Take a step back and assess the situation by asking yourself "why is my dog feeling uneasy, and what can I do to help her?"
TIP #2: HOLIDAY HEALTH & SAFETY
