I've changed name for this, as I'm fully expecting to get my arse handed to me, but I'm completely miserable.
Some background:
Puppy is 6 months old, and a standard labra/goldendoodle, weighing 22kg already.
She is incredibly friendly - but massive. We have been working hard on keeping her paws on the floor at home to prevent jumping up (all bets are off with visitors).
She pulls on the lead massively if she sees small children or other dogs. Again, she's friendly, but obviously I don't want her going over to people/dogs we don't know.
She's much better off the lead when there are no people or dogs around, although recall appears to be getting worse, not better.
Yesterday we were out for a walk in a field, and she was off-lead as I had 100m of visibility in every direction and there were no people or dogs. Then suddenly, she just ran, and wouldn't recall. I chased after her, but she'd sprinted 100m to a path and knocked over two toddlers, and when I got there a few seconds later, she was still jumping up at the mum (who understandably was furious - I would have probably kicked her if I'd been the parent, so fair play to the woman who just shouted at me). I came home, shaky and tearful and could barely look at the dog.
So today I took her out and only allowed her on the long lead so we could do some recall practice (no off lead, as I can't trust her). I was picking up a poo, whilst holding the lead, and she suddenly started to run again, towards another dog. I stamped on the lead to stop her, but she pulled it out from under me, got away and jumped all over the dog. Thankfully the owner was fine about it (dog is very friendly - it would be a different story if she wasn't).
I've tried the Halti head collar and she just escapes from it almost immediately. I've tried double-leading her, which is fine for short walks but doesn't help me practise recall. (We have tried whistles, clickers, treats - it feels like everything.)
She is better with my husband who uses a much sterner tone than I do. But he can also physically control her - she can pull me off my feet.
I just feel I've bitten off a lot more dog than I can handle, especially as she's only going to get bigger, and I'm hoping someone can give me some advice other than "you shouldn't even have a dog", which is how I feel about myself right now.
