Dog Barks and Lunges on the Canal Path?

Quick answer

Most dogs that bark and lunge on a canal path are reacting to things that come at them fast on a narrow bank with no room to get away: bikes, runners and other dogs. The fix starts with more distance and quieter times, then teaching your dog a few skills at home before you ask for them on the canal. Keep the leash on. SRP asks canal users to leash their pets, and in Phoenix the city leash law applies on the bank too.

Why the canal sets dogs off

SRP says Valley residents can use more than 80 miles of canal trails for free, and pedal bikes are welcome on them. That makes the canal one of the easiest places in town to walk a dog (our snowbird guide covers canal-path basics). It also makes it one of the hardest for a reactive one.

Think about what the canal looks like from your dog's end of the leash:

• Nowhere to go. On one side is water and on the other is a wall, a fence or a drop to the street. When a dog walks toward you, there's no side street to duck into.

• Head-on traffic. On a long straight bank your dog can see another dog coming for a full minute. That long, building stare is often what tips a dog over.

• Things that come up from behind. Bikes and runners pass close and fast, often without a warning. A dog that's already on edge can spin and lunge at them.

• Busy windows. In the cooler months everybody wants the canal at the same sunrise and sunset hours.

Barking and lunging at other dogs or people is what trainers call reactivity. It usually comes from fear, frustration on the leash, or a dog that simply has no idea what else to do. It's very common, and it gets better with practice.

The leash rule on the canal

SRP's canal safety tips ask people to use leashes on their pets near canals. City rules apply too. The City of Phoenix says that outside of gated dog parks, the Phoenix Leash Law applies at all times and in all places. In Scottsdale's city parks, the rule cited on its dog parks page calls for a leash no longer than six feet outside a dog exercise area, which is a good length for the canal as well. Our off-leash guide covers the rest of the Valley's leash rules.

A loose dog that charges your leashed reactive dog makes everything harder, so it's fair to keep your distance and step off the path if you see one.

Walk the canal smarter this week

You can lower the number of blow-ups right away by changing when and how you walk.

• Pick the quiet hour. Mid-morning on a weekday is usually calmer than sunrise on a Saturday. Watch your stretch for a few days and learn its rhythm.

• Choose a wide spot. Some canal stretches have a dirt shoulder or a side path. Those few extra feet make it much easier to keep your dog calm.

• Have an exit plan. Know where the next bridge, ramp or side street is. When a trigger shows up early, turn around or step off before your dog reacts. Every reaction you avoid is one less rep of the barking habit.

• Put yourself between your dog and the traffic. Walk your dog on the side away from the passing lane, so bikes and runners pass you, not them.

• Use a regular leash. A flat four- to six-foot leash gives you control. Retractable leashes let a dog shoot out into the path at the worst moment.

• Keep sessions short. Ten good minutes beats forty tense ones.

Mind the water too. SRP tells people to keep a close eye on pets near canals and says never to jump in after a person or animal in the water; call 911 instead.

Skills to build at home first

Save the canal for later. Build these at home and on quiet streets, then bring them to the bank.

A name or "look" that works every time

Say your dog's name and pay the second they look at you. Practice in the living room, then the yard, then the driveway. You want a look that happens without thinking, so you can turn your dog's attention away from a bike before the stare starts.

An easy U-turn

Teach a happy "this way" turn with a treat at your dog's nose. When it's smooth at home, it becomes your way out of any head-on meeting on the canal.

Seeing a trigger at a distance

Find a spot far enough from other dogs that yours can notice them and stay quiet. Every time your dog sees another dog and doesn't react, feed. Over many sessions, the other dog starts to mean "good things happen," and the distance your dog needs gets shorter.

A loose leash

A tight leash tells a nervous dog something is wrong. Practicing loose-leash walking on your own street makes canal walks calmer for both of you.

If your dog also goes off at the fence when the pool tech arrives, our post on dogs that go crazy at the pool guy or landscaper uses many of the same skills.

When to get help

Call a trainer if your dog has redirected onto you or another dog during a reaction, if you've started skipping walks to avoid it, or if things are getting worse instead of better after a few weeks of careful practice. Starting early is easier than undoing a habit that's had a year to grow.

How Mark helps with canal reactivity

Reactivity is one of the main things Mark works on in the Home Program. He starts at your house, where your dog is calm enough to learn, and builds the attention, U-turn and loose-leash skills there. Then he takes those skills out with you to your own neighborhood and canal stretch, so you know exactly what to do when a bike or another dog comes around the bend. Mark works with families across the Valley, from Phoenix to Scottsdale.

If canal walks have turned into a fight, book a free consultation or call (602) 960-0011.

Questions about dogs that react on the canal path

Why does my dog bark at bikes on the canal?

Bikes move fast, come up from behind and pass close on a narrow bank. Many dogs react out of startle or fear. Walking on the side away from traffic and teaching your dog to look at you when a bike passes helps a lot.

Do dogs have to be on a leash on Phoenix canal paths?

Yes. SRP asks canal users to keep pets on a leash, and the City of Phoenix says its leash law applies everywhere outside gated dog parks.

Why does my dog lunge at other dogs only on leash?

A leash takes away a dog's option to move away or greet normally, so fear or frustration comes out as barking and lunging. That's reactivity, and it responds well to training.

What should I do if my dog falls into a canal?

SRP says never to jump in after a person or animal in a canal. Call 911.

Should I stop walking my reactive dog on the canal?

You may want to take a break while you build skills at home and on quieter streets, then return at calm times with a plan to step off the path early.

Can Mark help with a dog that reacts on walks?

Yes. Mark's Home Program covers reactivity, starting at home and moving out to the streets and paths where your dog struggles.
