Hello all, I could really do with some help and I will apologise in advance as I have a feeling this could be a long one! 
We picked up an 8-week old bitch pup on Saturday (Cavalier King Charles Spaniel) - Lula and already have a year old male - Oscar.  Since we got Oscar at 9 weeks of age he has always been very timid and wouldn't say boo to a goose.  Unfortunately he picked up Kennel Cough from the vets practice in between his vaccinations and missed out on the crucial socialisation period due to not being able to go out - despite us carrying him round the park every day and to the local shops.  Anyway, he's come along well, plays with certain small doggies over the park and seems to be very happy albeit quite aloof at times to other dogs. He is a hugely affectionate dog with my husband and I and loves a cuddle but has never shown any jealously when we've petted other dogs whilst out on walks. 
In comes Lula!  She is his complete opposite and a typical puppy; not timid, full of beans and quite frankly a bit of an irritation to him at times.  On Saturday he gave a her a wide berth which I could understand, on Sunday she attempted to play with him but he wasn't interested but since yesterday morning they have been playing really well together, with him occasionally telling her off when she goes too far.  The main problem is with their sleeping arrangements.  We have given her his old bed which he grew too big for but for some reason she has decided she wants to sleep in his bed. We have been trying to encourage her to sleep in hers and in the day I now take his bed away and leave just hers out which she willingly and happily goes to when she wants to sleep.
When I put them to bed on the first night she got out of her bed and into his and the look on his face said it all - he didn't want her there.  We put her back in her bed and she finally settled there (with a hot water bottle, ticking clock, toy, etc) and I found her in the morning curled up in a little ball on the kitchen floor in the corner behind his bed.  The next morning they were both in his bed but I could tell Oscar wasn't too pleased and then this morning I found her in his bed and poor Oscar squashed into her little bed! As I walked in she ran out of bed to greet me and went to step into her bed (which he was in) and he growled and nipped her. I don't think there is anything wrong with him telling her off  occasionally but I'm not sure whether to intervene with the sleeping situation.  Should I let them sort it out, try and separate them at night or do something else?  Any advice would really be welcome.  Many, many thanks.

I did have a chuckle when I read your post, sorry.

Don't worry, I think we have all been there when bringing in a new puppy.  Actually Oscar is doing very well if he is playing with her this quickly.

I would leave them to it, they will sort out their own sleeping arrangements.  I wouldn't be surprised to find Oscar has taken over his old bed as it has been given to her.

Enjoy them, give it a few weeks and you will be wondering what you were worring about. :)

LOL me too

My older cavaliers usually steer well clear of new puppies for ages typical male behaviour !

On the other hand my spayed female GSD adores all puppies & lets them take very great liberties-which is a typical female reaction.

He will allow her to boss him so far & then tell her off. this is all quite natural.

They sound as if they are getting along ok so don't worry. You might even find that he becomes more out going, I have a very"in your face with everyone "forward dog & a quieter dog. When they are not together the quiet one will ignore everyone except the person he is with, however together they are both over the top friendly !
