GPS trackers for small dogs
The honest version of this page: there is one size of Kin One, and on a very small dog that may be the wrong answer.
This page exists because the category pretends size is solved. It is not. Here is how to judge it, including the case where we are the wrong purchase.
Battery life and bulk are the same decision
Specs quoted without the collar
The number that matters is the whole worn assembly: strap, unit and tags together.
A month of battery has a cost
Long runtime means a bigger cell. Lighter trackers usually charge more often. Pick your trade.
Puppies outgrow the problem
If they are still growing, the fit question has a different answer in six months.
Marketing that never says no
Most of this category will happily sell you the wrong size. We would rather lose the sale.
How to judge the fit
Ask your vet about neck load
They know this animal. We do not.
Weigh the full assembly
Including the collar and any ID tags already on it.
Watch them wear it for a week
Rubbing, posture and whether they stop moving normally.
Decide what you would do with a lighter unit
If the answer is a monthly plan, work out the multi-year cost first.
Terriers, toy breeds and puppies
The behaviour wants a cellular unit. The size question is still the vet’s.
Be sceptical. Get sign-off before you order anything in this class.
Consider waiting. The fit changes, the escape risk usually does not.
If the others suit it, no-plan hardware stops the invoices stacking.
How Kin Watchdog works
Set up the tracker
Charge Kin One and switch it on. The SIM is already inside and already paid for — there is no carrier to call.
Add it to your family
Scan the code in the Kin app and name who wears it. Authorised family members see the same map on their own phones.
View location
Open the app for whether they arrived or left a place you named. Follow mode is a live position only while you are looking.
Create alerts
Draw a safe place — home, school, the yard. One nudge on arrival, one on leaving. Nothing in between.

Small dog GPS questions
Do you make a smaller version?
No. Kin One is one size and there is no miniature in the range.
What does it weigh?
We do not publish a figure on this page rather than quote one we cannot stand behind. Ask before ordering, and return it within 30 days if it does not suit.
Is it the smallest dog tracker available?
Almost certainly not. If smallest is your requirement, buy on that and accept the plan.
Can I try it and send it back?
There are 30 days to change your mind and a two-year warranty.
Price?
$129.99 once, lifetime US and Canada 4G, $0/month.
