I know it was the right thing to do; she's 9 months, a terrier/min pin cross, and the interactions between my kids and the dog weren't really helping her. My DD1 in particular, whilst she adored the dog and is now distraught, just could not learn to respect the dog's space or back off when the dog signalled (why, I do not know). So before things got irredeemable we found her a new home - lovely older lady with 3 dogs (one of whom turned out to be ddog's sister). I'm gutted, I made a mistake (a reasonable one, but a mistake nonetheless). I know some of you will flame me and I probably deserve it. I really hope she has a happy life now.
