The legal limit where you walk
Rules are local, and they often apply only on park land. Here are real examples, so you know what to look for.
| Where | Most dogs at once | When you need a permit |
|---|---|---|
| San Francisco (city park property) | 8 | From 4 dogs, walked for pay. $333 the first year, $1 million liability insurance |
| Golden Gate National Recreation Area | 6 | From 4 dogs, with a Commercial Use Authorization |
| Toronto (city parks) | 6 | Permit for 4 to 6 dogs, $305.99 a year, $2 million liability insurance |
| West Vancouver | 6 | Commercial walker permit, park use permit and $2 million liability insurance |
| Tower Hamlets, London | 4, or 6 with a licence | Licence for 5 or 6 dogs |
| North Devon, England | 6, max 3 off the lead | Voluntary validation to have more than 3 off the lead |
Your real limit is lower than the legal one
Tower Hamlets set its everyday limit at 4 because, in the council's words, evidence suggests that's the most the average adult can be expected to control. A permit to walk 8 doesn't mean 8 is safe for you, on your route, with these dogs.
Size and strength
Two large dogs that pull can be harder to hold than four calm small ones.
Leash manners
One puller or lunger takes most of your attention.
Who gets along
One bad pairing can turn a calm walk into a fight.
Your route
Narrow sidewalks, traffic and other dogs on the trail all lower it.
On or off lead
North Devon allows 6 dogs, but only 3 off the lead unless the walker is validated.
Your hands
Bags, a phone and gates. Can you still pick up after every dog?
What the 4th dog earns, and what it costs
Here's an example from the planner's sample file, with made-up dogs and walkers at $22 a dog. Each extra dog on a walk adds $22 of revenue to a walk you were doing anyway.
- 4 dogs × $22$88
- Walker pay$31
- Mileage$5
Profit for the walk$52
A 3-dog walk in the same file makes $66, and $33 after pay and mileage.
That Monday walk is also the one the planner flags, because two of its dogs aren't allowed to walk together. That's the trade-off: the extra dog is where most of the profit comes from, and where most of the risk comes from too.
Build a group one dog at a time
Walk them solo first
Two or three solo walks show you leash manners, triggers and recall.
Write down the details
Size, energy, walk type and anything that sets them off.
Trial with one group dog
A short walk with the calmest dog in the group, on lead.
Join the full group
Only if the trial went well, and with the owner's OK.
Keep a "don't walk with" list
If two dogs clash once, they don't share a walk again.
Give each walker their own maximum too. A new helper might take 2 dogs while you take 4.
Dogs that walk alone
Some dogs shouldn't join a group at any size. Book them as solo walks and price them that way.
- Dogs reactive to other dogs
- New clients, until you've walked them alone
- Dogs the owner asked to walk alone
- Dogs on vet restrictions after surgery
- Puppies not yet cleared by their vet
- Any dog after a scuffle
Put it in writing for owners
Owners should know whether their dog walks alone or in a group, and the most dogs in that group. Tell them before the first group walk, not after.
Text or email to the client
"Hi Sam, from next Monday Biscuit will join my 9:30 group walk. It's never more than 4 dogs, and I've walked each of them on their own first. If you'd rather Biscuit kept walking solo, just say and I'll keep the solo slot."
After each group walk, a short report tells the owner how it went. Our free pet visit report cards include a dog walk design, with space for water, potty, mood and notes.
- Check the limit and permit rules where you walk
- Ask your insurer if your policy caps the number of dogs
- Agree solo or group walks with each owner
- Set a maximum per walker, not just per business
Frequently asked questions
How many dogs can a dog walker walk at once in the UK?
There's no national limit. Councils set their own through dog control orders (PSPOs). Tower Hamlets in London allows anyone 4 dogs, and 5 or 6 with a professional dog walker licence.
North Devon caps it at 6, with no more than 3 off the lead unless the walker is validated. Check your own council's website.
Do I need a permit to walk 4 dogs?
In some places, yes. San Francisco requires a commercial dog walking permit to walk 4 or more dogs for pay on city park property, and Toronto issues permits for walking 4 to 6 dogs commercially. Many places have no such rule, so search your city or county name plus "commercial dog walker permit".
How many dogs should a new dog walker start with?
Start below any legal cap, with dogs you've already walked on their own. Two or three dogs you know is a sensible first group. Add one dog at a time, and only after a trial walk with the group.
Can I walk dogs from different households together?
Yes, if the owners agree. Say in your service agreement whether a walk is solo or group and the most dogs in a group, and get each owner's OK before their dog joins one.
Does my insurance limit how many dogs I can walk?
It might. North Devon Council notes that many professional walkers are already limited to 6 dogs for insurance reasons. Ask your insurer for the number in writing before you grow your groups.
