Hi,
So we've been thinking about getting a second dog for a while now, but ideally a smaller dog than our lab X cocker, mainly for space tbh, as our house isn't massive.
Our dog is 2 and is FULL of energy, but has calmed down a bit in the past couple of months. She's lovely with other dogs and very playful. Never aggressive, although does sometimes need to know when to back off 
Anyway, someone I know has a one year old Frenchie that they can't afford to keep anymore, due to unforeseen (pressumably financial) circumstances. Apparently she doesn't have any health issues, which I know is notorious with this breed. Actually, before I go on, I understand the controversy of this breed, but I wouldn't have been interested in a puppy, as I don't necessarily agree with continued breeding of them, but this is essentially a rehoming. I wouldn't be interested in breeding her, but anyway, I'd rather not get into a debate about that.
All that aside, after researching their temperament, she could actually be a good fit for us from the sounds of it.
So, if we did go ahead, does anyone have any tips or advice on how to make the transition/introduction run as smoothly as possible?
They'd need to sleep in the same room (kitchen/diner)but the plan was, at different ends of the room.
Do dogs normally just accept a new addition or are there usually teething problems? I know this can vary so much, but just wanted to hear your experiences.
My main concern are the sleeping arrangements tbh. Our dog just goes to bed and sleeps through til morning, so am concerned they'll disturb each other in the night.
I should also say, we honestly think a buddy for our dog would be really good for her, as I think she can get a bit bored and as I say, she's great around other dogs.
Thanks for reading
