New puppy...

Another vote for petal cleanse. My sister is allergic to cats but I use to wipe the cat over and she was fine.

Ah you should never have caved (and I am a dog owner). Seriously I would rehome now while she is still little and your children haven’t bonded too much with her.
Your allergies are likely to get worse not better and you can’t live for the next potentially 15 years changing bedding and clothes all the time and endlessly vacuuming.
Aside from the allergy issues your DH is annoyed already after a week, training a puppy takes a lot of time and patience in the first year! I think he thought you’d cave and end up doing everything for the puppy.
After the paying him back for the puppy comment I’d be tempted to ask him to leave and take the dog with him.

My DD was desperate for a dog but is allergic to some. We got a puppy 2 years ago and use an air purifier and a spray I get from Amazon that kills the pet dander in carpets etc.

Fingers crossed she hasn't had a reaction since the 1st week.

Spray is Allasearch, might be worth a try.

You made a mistake in agreeing to get a dog when you know you are allergic to them. You are now going to compound that mistake by trying anything and everything to control the allergy and all because you don't want your partner to be pissed off and your children to be disappointed. What kind of partner is he if he'd rather you felt unwell than get rid of the dog or insist you reimburse him if you do have to re-home the dog?

You have three choices:
The dog goes.
You go.
You live like this for, potentially, 15 years.

If you care about the dogs welfare at all you will re-home it now. It will also be harder for the children the longer you leave it. Stop pandering to your sulky partner and put your foot down, it will be better for everyone in the long run.

Does your partner work?
Who will look after the puppy when he is at work/playing sport/out doing hobbies?
Who will walk the puppy if your partner is ill?
Who will have the puppy when you go on holiday or out for family days?
Where will puppy go if you have a family wedding, funeral, one of you is in hospital or during medical appointments?
Who will be doing all the dog related cleaning? Washing of muddy floors, blankets, towels, coats?
Who is responsible for socialising pup? During the formative months your pup will need to be exposed gently to all experiences from meeting other dogs, horses, other animals, all sorts of other people, traffic, noises, travelling by car and public transport?
Have you considered costs of pet insurance, vets bills, flea treatments, food, kennels, dog walkers, medication etc? Medication for you and the puppy?
Who will walk the dog on wet nights and dark mornings?
Who will scoop poop in your garden so your kids don't trail it into the house?
You go out for a dog walk and can't take the dog in a shop or cafe - who will stand outside with the pup whilst the rest of you sit in? Or will you all go home?
How will your partner react when pup soils the carpet or chews his best boots?
Will your partner always be available to take pup to the vets?
How will you travel in a car with the dog that makes you ill?

Honestly OP. Your allergy is only the tip of a 15 year iceberg.

Even hypoallergenic breeds, which this is not, arent allergen free. They just supposedly shed less allergens.

Most allergens are in the skin flakes, urine, and saliva though and all dogs produce those. Hypoallergenic dogs just shed less hair, usually have tighter curls that trap allergens closer to the skin meaninf regular professional grooms are necessary to prevent matting, moisture retention and skin issues which cause more flaking and many are small breeds so there is less surface area to shed flakes from. There's no such thing as a truly hypoallergenic breed.

Some allergies to pets get better as you increase your exposure, however some get infinitely worse.

Op you shouldn't have let your dp bully you but you absolutely should not allow him to treat you like shit for a known health issue that his actions have worsened.

I have no advice, other than now is probably a good time to start aligning your ducks in a neat row and getting the hell out of that relationship. Your dp has shown his true colours here.

You've only had her a week. That's no time at all.

what a twat.

I try not to post when angry, but for fucks sake! Rehome the poor thing, and quickly. None of you sound like you want it, and never, ever get another dog, especially from charlatan ‘breeders’ who just want the money.

I wonder what state the pup’s mother is kept in…

Petal cleanse. Buy it online, wipe puppy with it daily, it reduces the dander (skin flakes) that cause our allergies. Harmless to the pet.

I'm very allergic so would never consider getting a dog. Just being around them for a few hours leaves me feeling rough for a good few days, even taking antihistamines.

I have heard anecdotally that people become immune to their own dog after a while but don't know how true that is - I've never been willing to risk it!

And what on earth gave him the idea that this mongrel could be hypoallergenic?

You might find the allergy symptoms go away in time. I was allergic to cats until we got our cats.

I suppose first thing is, do you want to find a solution to try to allow you to keep the dog?

Maybe try an air filter to in each room downstairs to keep on top of the dander. Don't allow the dog upstairs, get a stair gate. Try a robot hoover ran downstairs twice a day or hoover twice a day.

Though if you are struggling and the allergies dont settle down, then maybe its too much, whether your partner likes it or not. You can't suffer for 10-15 years

How much did he pay for this expensive mongrel?

There are wipes you can use on the dog, think called petal cleanse or similar. Hopefully will help.

By the way... There's no such thing as a "maltipoo cockerpoo breed".
It's a mutt. And mutts are great.
But it's a mutt. End of.

Ultimately its the problem of a 9 week old puppy that is going to go from a family home to kennels, because someone with allergies decided they'd give it a try.

What an absolute shit show.

I don't see how you can continue to live with the dog if you are already trying antihistamines and limited contact but you are still having reactions. It's not going to work OP and you know it.

As far as your DH is concerned you need to give this relationship some serious thought. He sounds dreadful.

I would bet money that in no time at all DH will get fed up of all the effort needed with a new puppy and will suggest rehoming it ..but he's going to blame you .

Poor dog deserves better.

she is a Maltipoo x cockapoo

So not hypoallergenic at all, and probably poorly bred on top of that. Does your 'DP' know how expensive some of the health issues of these breeds are? Tbh, the 'breeder' (puppy farmer) isn't going to take the dog back so you are going to have to rehome.

But this is, ultimately, a DP and DC problem. They put their own selfish needs above yours, and i'd be pretty gutted as a partner and as a mother.

I had allergy symptoms when I got my pup, got used to him in about a month and they stopped. That first month was awful, puppy cried, I cried, I wanted to take him back to the rescue because he kept eating his own poo 🤢 it was bloody hard work for me as I wfh and I was trying to house train him. It is ok now 7 years on but we are tied, no spontaneous days out, weekends away as he cant be left more than 4 hours, holiday boarding is expensive.
I love him but I wouldn't do it again.

Unfortunately not all pet allergies are like this.

I went from mild cat allergy to full facial swelling over my last cats lifetime. We tried everything, I had multiple antihistamines a day, the non drowsy ones even knocked me out because that's how the histamine system works, she was wiped with hypoallergenic wipes specifically for pet dander, we gave her a specialist diet to try and reduce the production of allergens, but in the end none of it mattered. I developed pleurisy, my lungs felt like I was breathing sandpaper.

I don't think it's realistic to expect OP to overcome her dog allergy or to take a dogs lifetime of medication either.

Your husband doesn't sound very nice op. I would be more bothered about his response than the dog.

Have you checked terms?

you may get a refund if you return to your breeder? Definitely Check this out.
