Dog Aggression Help in Highland Park and Chicago’s North Shore

If your dog growls, lunges, snaps, or bites, you may be worried about what happens next. You may have tried trainers, tools, or advice that made things worse. Aggression can have many underlying causes, and understanding your individual dog and household is where we begin.

Canine Family Guidance works with Highland Park and North Shore families, with remote assessment available across Illinois. In-person availability and travel are discussed for each case. You can reach Marnie directly at (872) 222-3851.

What are you seeing?

• Growling, snapping, or biting when people approach, visit, or touch the dog.
• Fights or threatening interactions between dogs at home.
• Tension around food, toys, furniture, people, or shared space.
• Barking and lunging around dogs or people on walks.
• Changes in behavior that need a closer look at health, context, and the dog’s history.

Start with the sequence

“Aggression” describes a concern; it does not explain its cause. What happened just before the dog tensed, growled, or lunged? Who moved, what changed in distance, and what happened afterward? How does the same dog respond in other settings? Those differences help us understand the case before choosing what to change.

How individualized support works

2. Video behavior consultation. We review suitable video and your dog's context together, remotely anywhere in Illinois. In-person visits may be available near Highland Park.
3. Your individual plan. Guidance built around your dog, household, and the observations we make together, with follow-up options.
