I speak from experience in this area

Smokey, my buddy who I rescued as a six-week old baby



had to be rehomed a while back at age two and a half.

(smokey at one year old)



Although he grew up with the kids, he was just too nervous and if any little people scared him or cornered him he would automatically snap.
The sad thing is that he loved the kids and only reacted instinctively, and immediately felt bad about it.
He's in a fabulous new home (thanks to border collie rescue Wiccaweys.org) and they have two teenage girls (great because he has LOADS of energy!)

But I had to do the responsible (however hard) thing and choose to rehome him because we had two incidents where the baby was bitten on the face (well, snapped at and accidentally made contact)

Anyhow, it's just the responsible thing to do, for the dog and for the family.

JMO I miss him.
