Puppy in heat; slowly going crazy

Hi friends! Sooo my 7 month old puppy is going through her first heat cycle and I think I’m slowly losing my mind.

I’ve had female dogs in the past, but they’ve all been rescued and spayed before I got them, but current Bebe was too young when I rescued her.

Took her to the vet and he said newer evidence is showing to wait until they’re “skeletally mature” for spay so I’m gonna go with what’s in my girls best interest health wise.

But guys- I am on the STRUGGLE bus and have so many “dog mom” questions my vet obvi cannot address in one small appt. So if anyone has experience and can help (sans judgment please to all the trolls) ya girl needs to know Its gonna be okay.

She has officially un-potty trained herself. Previously, 4-6 months no accidents to speak of. Now, she like REFUSES to go outside and then when I force her she just stays out and barks at the wind. Occasionally will poop. Then I’ll let her back in and like 5 mins later-puddle on the floor. I’ve started having to go outside with her or walk her every morning so I don’t come home to any surprises.

She also hasn’t been eating as much (of her food. She goes after the cats food like a wild hyena). And she will eat treats and other delicacies but she is officially a diva and her dry dog food with chicken broth is now for plebeians.

I just don’t know how to gauge what’s “normal” vs what’s “concerning” and how to handle it. I really don’t want her learning it’s okay to pee in the house again and like I am paying way too much for a rental with a yard just to have to go outside with her to get her to pee anyways. I have diapers as well that are as ridiculous as they are adorable But I like to give her time out of the diaper cause like…I wouldn’t wanna be in a diaper all day long either.

If anyone has any advice, tips, commiseration, etc I could use some cause I’m just trying to take care of my Bebe girl but I’ve never done this before!!!
