- For Dogtra units over two years old from the
purchase date, the batteries may need to be replaced.
You can replace them yourself by contacting Dogtra.
But, damages incurred to the unit due to improper
battery installation are not covered under any warranty
and any other unauthorized servicing or tampering
with the unit voids your limited lifetime warranty. This
will be up to the user's discretion. If you are still having
problems after replacing the batteries, Dogtra strongly
recommends sending the unit in for inspection.
