My puppy drastically changed overnight.

She’s an american black lab and i got her at 8 weeks old, she was the typical puppy. Constant biting/mouthing, endless energy, ripping up things in the house etc etc. She was SO difficult, i was suffering from the puppy blues and everyday i debated if i should give her away. I have scars on my entire body from her biting me, tons of things were ruined in the house, she didn’t settle at all unless she was in her crate and honestly she was like HELL ON EARTH.

She’s turning 8 months old in a few days and she’s completely changed. Around a month ago, i woke her up on the morning to take her out and she was weirdly calm. I made up her food, she sat and waited for it (usually she would jump up for it) and then played with her toys for a bit and suddenly went to sleep right next to me. This was the FIRST time she had went to sleep outside of her crate since the day i got her, i was in absolute disbelief, and she was sound asleep for a good hour and a half. I enjoyed the moment and cuddled with her and prepared myself for another horrible day once she woke up, but when she did… she just laid there playing with another toy.

She is currently asleep on my bed. I’ve looked up this sudden behaviour and made sure that she’s not lethargic, she still gets excited for EVERYTHING but maintains it so much more better. She now signals to me when she needs to go potty, cuddles me everyday, naps outside of her crate everyday, way more calmer and overall a lovely girl. I never have to fight with her everyday now, i do still need to correct her constantly with the “leave it” command and she listens so well.

I really don’t know how or why she changed overnight, she puts herself down for a nap so she is rarely ever in her crate unless it’s time to sleep on a night or if i need to go out. She is now allowed in my room without me worrying that she might break something or pee on the carpet (accidents occasionally happen but it’s not an issue, she’s still learning.). I really don’t know what happened to her overnight but i now wake up every morning excited to see her, happy to spend the whole day with her but how on earth did this happen!?

We have trained everyday since the day i got her, settle training took 5 months every morning to finally click. Toilet training is 90% successful. She never bites anymore and i can even put my hands in her mouth and she will be the one to turn away from me. Has anyone else ever gotten this with their lab? I was expecting her to only be like this in a few years time, never mind at nearly 8 MONTHS OLD.
