Thread: What to do with 308 when I start with my dog

Have started training my pup and all things going well, will be hunting with him next winter.
I am currently running with a Tikka T3 308 18” Hardy Can. Scope is a VX5.
I’m very fond of my shooting set up and would like to stick with it.

Things to note,
-I don’t reload and don’t plan on getting set up to do so.
-I won’t be hunting every week, so don’t foresee putting 100’s of shots over my dog. But I do plan on going out at least every month.
-Majority Bush hunting

What is practical in terms of not stuffing up my dogs hearing?
Is there a factory sub I could use?
Or is this not an issue I should worry about?

Any thoughts are much appreciated
