Rescue greyhound bit our child’s face

are we doing the right thing sending our rescue greyhound back to the kennels?

we adopted a gorgeous 2 year old retired racing greyhound about 6 weeks ago. had a few issues at the start but he has now settled in nicely and we love having him here

we also have a 4 year old son, who isn’t the best listener, we’ve always been super careful not leaving them alone etc

the other morning I was standing at the cooker preparing food (downstairs is open plan so i was in the same room meters away - dog and child were on the sofa)

noticed my child was putting a blanket on the dogs face so asked him to stop that, trusted that he did (my fault- i shouldve went and took the blanket off him but it was 6am I wasnt thinking too rationally) and then there was a bark and a scream. our dog had nipped my son in the face. no blood but It left a mark

there’s been 2 other occasions where the dog has went for me and my partner but both times had a reason ie sleep startle (I got up off sofa when he was sleeping nearby and he got a fright, i didnt Intentionally startle him)

we’ve been going back and forth with the decision for the last couple days as were gutted this has happened but we have decided we’re going to take him back to the kennels over the weekend.

im so sad about this I feel like we haven’t given him a fair chance but also can’t risk anything worse happening to our son. hes at school during the day and now we muzzle or crate our dog when he’s home until our son goes to bed

are we making the right decision? each time he’s snapped has had a reason to; he isn’t aggressive usually.

im really going to miss him

Thank you
