Was a rescue with a sad history, not suitable around kids, spent some time making sure he goes to a suitable home but didn't work out. He came back to me and I pts as he'd bitten new people badly. I think he couldn't cope with the rehome again but I couldn't trust him around my baby. I feel wracked with guilt that I gave up on him then swing to telling myself that a dog that troubled and neurotic is not a happy one. We tried trainer and a behaviourist suggested he be pts as rehoming again following the failed one would be unsuitable and I agreed. Anyone been in a similar situation? My childhood dog was pts for health reasons and that felt a lot easier
