Dad, new GF & puppy drama

[MMoon23]

I have a newborn baby (10 weeks old)

My dad is coming to visit soon from a few hours away to do some work on our house / visit the baby for a few hours. He mentioned on the phone that he is bringing his new girlfriend (we’ve met once before, she’s a bit odd but trying to reserve judgement) and her new puppy (9 weeks old) to our house with them.

AIBU to feel uncomfortable with this? I share an older dog with my ex partner and I am very careful about managing my dog and baby when she is with us (one day per week) and we have strict boundaries for the two of them. I haven’t met this puppy and even though they will be small - I feel it will still be risky particularly as they are not at all trained and my dad is quite oblivious and probably won’t follow any instructions/rules for the visit if I give them.

AIBU to think it is odd that someone would just assume this would be okay without talking it through?! I adore dogs but I am a new parent and don’t want to overlook things that could negatively affect my baby.

Update - I’ve now told him no and the reasons why, rang him to clarify, turns out new gf was in the car and he hadn’t mentioned the trip to her and now he’s being really weird with me. I didn’t say anything bad about the puppy. He said he thinks it would be fine but I said no.

Why can’t he just come on his own to see his grand daughter ffs. Can he not spend 1 day without new gf and her puppy?! Last time he came to visit he did some work on the house, barely said a word, was on his phone texting gf for the whole lunch I made, didn’t really interact with baby or ask questions about her.

I don't think YABU. I wouldn't be happy about my dad bringing someone I essentially don't know into my house with their puppy when I've got a new baby and imagine you're already feeling pretty overwhelmed! I'd tell him no as well.

Had the puppy had its full first vaccine schedule?
in any event regardless of that as someone else who has an older dog and young children, no I would not mix them.
my dog is in charge of her territory and incredibly protective of my children. She would hate a puppy being thrown into the mix.
ny children are very responsible to and sued to being around dogs bit even so their enthusiasm for a nine week old puppy might be difficult to contain

as a responsible dog owner and parent is be inclined to say no. Fairest on the puppy as much as anything or anyone else too

Sorry pressed send too soon with a newborn I definitely would not be having the puppy over

No, she can't come to visit the baby with her puppy. Start saying no and keep saying no. An appropriate visit would be grandad with or without girlfriend visiting for 2 hours. And grandad giving a gift or cash. Then leaving you to it.

You will have to not accept DIY help from your dad, if he is going to pull this nonsense.
