The next time your dog dives for something on the ground during a walk, it may be more than unpleasant—it could be dangerous. According to the Pet Poison Helpline, poisoning ranks among the top causes of emergency veterinary visits in the U.S., with over 1,000 cases reported each day.

As warmer months bring more frequent walks, the risk of dogs encountering harmful items increases significantly. From discarded food and toxic plants to residues of substances like antifreeze or xylitol, everyday streets and sidewalks can pose real hazards for curious canines.

Karen Piwinski, a certified dog trainer with Woofz by nove8, says this behavior is more common—and more instinctual—than many pet owners realize.

“Scavenging is in their DNA. It’s how their ancestors survived,” Piwinski explains. “Your dog isn’t being bad—they’re acting on natural impulses. But natural doesn’t always mean safe.”

To help prevent a trip to the emergency vet, Piwinski shares four expert strategies to curb the urge to snack on walks and maintain good pet health:

1. Teach a Solid ‘Leave It’ Command

“This command can be a lifesaver,” says Piwinski. Begin indoors with two treats—one visible and one hidden. When your dog reaches for the visible treat, say “Leave It.” As soon as they stop or look away, reward with the hidden treat. Never give the one they were told to ignore. Gradually move to floor-level items, and eventually practice outdoors. A well-reinforced “Leave It” can help your dog steer clear of everything from food scraps to hazardous chemicals.

2. Keep Walks Structured and Focused

Uncontrolled sniffing and zigzagging often mean you’ve lost your dog’s attention. Use a 5- to 6.5-foot leash and maintain a steady, purposeful pace. “Be unpredictable—change direction, ask for focus, and keep them engaged with you,” Piwinski suggests. Allow brief sniffing breaks, then move on. If your regular route is cluttered with trash or hazards, consider driving to a cleaner, safer walking area.

3. Reward What You Want to See More Of

Most owners only respond when their dog misbehaves—but reinforcing good behavior is just as important. “If your dog walks past something tempting without reacting, immediately praise and reward,” says Piwinski. Consistently recognizing good choices helps reinforce them and shifts your dog’s motivation.

4. Train Gradually in Low-Distraction Areas

Avoid jumping straight into busy streets or parks. “Start indoors, move to a quiet backyard, then try calm sidewalks,” advises Piwinski. “Only increase the challenge when your dog is consistently successful. If they regress, return to a simpler environment to rebuild their confidence.”

Know the Signs of Poisoning

While training is key, early detection is also critical. Watch for symptoms such as drooling, vomiting, lethargy, tremors, or loss of coordination. If poisoning is suspected, call your veterinarian or the Pet Poison Helpline immediately at (855) 764-7661.

Being proactive is the best way to keep your dog safe. “It’s not about panic—it’s about preparation,” Piwinski says.
