@Plantlover23 What a beauty! To answer some of your questions from yesterday, I'd say our pup is toilet trained but not sure about fully. She has accidents in other houses, so if she's over at DP's parents' or sister's house she'll wee on the floor sometimes. We honestly haven't had an accident in our house since before Christmas so I'm not sure if it's because she doesn't know how to get out, is too excited and cba going out, or if they're not reading her signals and not giving her enough opportunities. We still pop her out every couple of hours so she has the chance to go. We'll likely just naturally extend the intervals between trips out as she gets older. Your pup is still super young so I wouldn't put a deadline on it, it'll just happen.
And as for when she became more chilled, she calmed down a bit at 12 weeks once the walks started. Biting reduced around this time too. Something clicked in her around Christmas and she just became more pleasant to be around. That was around 17 weeks and I'd say that was the point her attention span improved to the extent she would sit and play with a toy alone, or focus on a training session. Have you tried a chew like a cow ear? That was the only thing that bought us a moment's peace when she was little.
@PugInTheHouse It always sounded like you were lucky with Pugpup very early on, being able to hold his bladder so long. Going back to basics sounds sensible. Ours is 5 months and still has maybe 3 or 4 wees after dinner. But then she's quite energetic so she drinks a lot too.
