Awww.
We always trained dogs [and horses] to the gun by having them outside while shooting so they would understand it was just a noise.
Even my Dobes freak out when someone is shooting outside because they just can’t figure out what’s happening.
Oddly, the sight hounds couldn’t care less about guns or thunder.
It’s been too cold to have him running outside free, but soon, supposed to be mild for a bit.
