Can anyone give me some advice for my dog :(

[baba19]

I've had my girl Petal for a month now, she's one years old staffy/pug.
She has just finished being in season, but my circumstances have changed and i'm having to move out of my house into my mums house,
The problem is that my mum has 3 dogs,
A 14 year old staffy girl name star
A 16 month old staffy boy named Diesel
And a 13 month old male Chihuahua
Petal has met the dogs on walks and we have started taking her around my mums house as ive got about a week to move out in, and things are not going so great.
Petal and star get on great, as star doesn't really bother with her and just keeps herself to herself, theres no issues between them
But the two males are a nightmare with her
The Chihuahua boy is CONSTANTLY after licking her girl parts and will not leave her alone for a minute, she doesn't seem too bothered about it but she keeps climbing on top of him and showing dominance, growling and humping him, which he just wags his tail at, but again its not the best situation i don't want it to turn into fighting or anything, and like i said he won't stop going for her girl parts which is a bit of a pain
The Male staffy Diesel is quite shy but he's a really big dog, he towers over all of them, he means no harm but he keeps jumping on top of her (hes a gentle giant)
But she seem's to be more aggressive towards Diesel, showing her teeth and snapping at him if he comes too close, i really don't want to end up with a dog fight on my hands if he decides do react back
I'm so attached to my Petal, i adore her so much but my family have said which i understand, if things don't improve i will have to re-home her as its not fair on any of them,
Is there any way i can get them to get along with each other? I can't spay her until June
And the male dogs can't be neutered until a later date,
I really need some advice i'm getting so stressed and its really hard on me as i'm also 27 weeks pregnant,
I just don't know what to do to make them feel more comfortable around eachother/ get them to leave her girl parts alone 😢
Sorry for the long post

It's probably the lingering effects of her being on heat. Even my neutered boy has shown a great deal of interest in girls at the same point!

I'd be getting her spayed ASAP (ie June) and keeping her separate from the other dogs in the meantime. Baby gates are a great way of controlling access, and will presumably come in handy in the not too distant future with your new baby (congratulations, BTW)

Agree with avocado. Get her spayed asap.
There are ways to help dogs get along you can't give up on her, remember its early days & they will get used to one another. Give tgem as much space as possible- this will make ot easier

Get her spayed ASAP.

If she's only just come out of season, that would explain her behaviour. She is only young still.

Congratulations on your pregnancy

even if she is no longer on heat the affects will still be there, keep them apart

[Doggydoggydoggy]

It’s the lingering effect of her heat as others have said.

The growling and snapping is very normal.
Keep them apart for the time being

You have to separate. It all sounds entirely normal but if you let it continue as well as your girl getting annoyed, you risk fights starting between the two boys. It can all be avoided if you act now and put up stairgates to keep them apart.

I would expect them to settle down once she is spayed but until then you want them to live together without the hassle. If she's just finished a season then maybe a good bath or a groom to change her smell?
