TAMPA, Fla. (BLOOM) — The next time your dog lunges for something on the sidewalk, it might not just be gross, it could be dangerous. Poisoning is one of the leading causes of emergency veterinary visits in the United States, with more than 1,000 cases reported daily, according to the Pet Poison Helpline.

As spring and summer bring more outdoor strolls, the risks of sidewalk snacking increase dramatically. From discarded chicken bones to toxic plants and even remnants of harmful substances like xylitol or antifreeze, the urban environment can quickly become a minefield for curious pups.

Karen Piwinski, a certified dog trainer at Woofz by nove8, says the problem is more common, and more natural, than many pet owners realize.

“Scavenging is instinctive. It’s how dogs’ ancestors survived,” said Piwinski. “Your dog isn’t being disobedient—they’re just doing what they’re hardwired to do. But that doesn’t mean it’s safe.”

Here are four expert-backed strategies Piwinski recommends to stop the “sniff-it, snack-it” behavior before it turns into an emergency vet visit:

1. Teach a Reliable ‘Leave It’ Command
“This is a lifesaving cue,” Piwinski said. Start training in a quiet space using two treats—one in each hand. When your dog goes for the first treat, say “Leave It.” The moment they pause or look away, reward them with the second treat. Never give the one they were told to ignore. Progress to floor-level items, then eventually practice outside. A consistent, well-trained “Leave It” can prevent dangerous encounters with everything from chicken bones to street drugs.

2. Walk with Purpose
If your dog is zigzagging, sniffing constantly, and pulling in every direction, you’re likely not in control. Piwinski recommends using a 5- to 6.5-foot leash and maintaining a brisk pace. “Be unpredictable—change direction, cue focus, and keep their attention on you,” she said. “Give short breaks where they’re allowed to sniff, then get back on track.” And if your usual walking route is littered or dirty, consider driving to a cleaner, safer location.

3. Reward Good Choices, Not Just Bad Ones
Most dog owners react only when their dog misbehaves, but rewarding good behavior is key to changing habits. “If your dog walks past a tempting object and doesn’t lunge, say ‘Yes!’ and offer a high-value treat immediately,” said Piwinski. Over time, dogs learn to ignore street snacks in hopes of earning something better from you.

4. Train in Low-Stress Environments First
Don’t expect your dog to perform perfectly in a chaotic environment without preparation. “Build up gradually,” Piwinski said. “Start training ‘Leave It’ or ‘Focus’ indoors, then the backyard, then a quiet street. Only when they succeed in those environments should you try busier sidewalks or parks.” If your dog struggles, take a step back to a calmer training zone and rebuild confidence.

Emergency Awareness
While training takes time, knowing the signs of poisoning can also help. Symptoms may include excessive drooling, vomiting, lethargy, tremors, or loss of coordination. If you suspect your dog has ingested something toxic, contact your vet or the Pet Poison Helpline immediately at (855) 764-7661.

Dog owners are encouraged to stay vigilant and proactive. “It’s not about being paranoid,” Piwinski said. “It’s about being prepared.”
