sister/dog tired rant

Basically her dog got hit by a car yesterday, he's had stitches in his leg and is ok. So she stopped at home (I'm currently at my mums waiting to have baby due to long health issues and husband working weird shifts/away) rather than going back to hers as her housemate/friend has a dog - which I totally get and understand she doesn't want the other dog irritating hers etc - not an issue.

What I have an issue with is the dog sleeping on my bed (long story short my sister has never lived in this house apart from a few months when she left her husband)  which is why I say it's my room and my bed as it was for 20 years till I married and moved out. That maybe wrong of me but tuff. 

I was ok with the dog on the bed (this once) and sharing the bed with my sister however all night the dogs been licking its wound, whimpering as it's wanted to get in bed with my sister, I've had to wake her to let him go for a wee, I've had to be on my side with about 6 inches of bed because she has taken up so much room in the bed with the dog crawling over me/jumping off me onto the floor then her calling him back up etc. I've had very little duvet most of the night as she keeps pulling it off me so I'm freezing.

I'm due to give birth next week (if comes on due date, like in 4 days), I feel shocking from a sore throat and bad cough and ear ache and now I'm getting a headache due to no sleep.

On top of all this (I don't care if she's kidding) she keeps asking to put the dog in the Moses basket and on the pram - NO!!! I won't even let my hamsters near the baby stuff I'm not letting a dog near it!! I get the dog is her baby I do but this is my actual 'spontaneous conception' as it says on my medical records baby that I thought I'd never have. Now I won't be totally paranoid but at least give me chance to have the baby!!!  I know he is excited about her niece/nephew but even when I announced to her that I we got a positive all I got was;

'Your going to get fat' 

And

'Don't forget (dogs name) was here first'

And

'(Dogs name) is your first grand child.

Stop comparing my baby to the dog!! I don't even do that with my fur babies (which have been around longer than the dog!)

Sorry I'm tired I just needed to rant as there is only so much I can cope with.
