I strongly suspect I will get my arse handed to me for being a fool - I must be a masochist. But I need advice. My 4 month old rough collie puppy has over the last few days started to seriously target my 19 month old. It’s clearly herding behaviour, but she’s leaping at her with mouth open, knocking her over, nibbling at her arms. It’s not directed at anyone else, not my 5 or 9 yo. Today when I was upstairs with a relative looking after them all downstairs, the puppy apparently targeted her repeatedly, jumping on her and my LO now has a big scratch near her eye.
Up to now, the puppy has been lovely - her sweet and friendly temperament has been much complimented. Clearly she sees LO as a litter mate - and LO will, if we take our eyes off her at all, will run around her to entice a chase. Yes, we were stupid to get a puppy with a toddler. But it’s done now. Is this situation salvageable or do we need to return puppy to breeder before LO gets injured and a good puppy gets ruined? The kids will be devastated if she goes and I will be deeply ashamed. But it would be worse if my LO suffers a bad facial injury. I have emailed a trainer/behaviourist but she has no appointments until end June. Should I see if we can make progress to solve this in the meantime but wait for the behaviourists input?
