How to introduce Grey to a new puppy brother

[Moo]

Sorry for two threads on one day! 

I'm living with my parents at the moment who have just got a 4 month old border collie pup. So chalk and cheese having a collie and a grey in the same house. 

 

We did gentle introduction outside, Rumble (grey) was very patient and gentle, and wagged his tail which was lovely to see, as he's a quiet boy who never really gets to interact with dogs much. We've been keeping them both in the living room, but the room is separated by a somewhat clandestine bollard made of a coffee table. This way Rumble gets to peep over so he's not excluded, and pup can't pester Rumble. 

 

When it gets up the stage when puppy can go out for walks, we'd like to be able to bond them a bit more, so I have a couple of questions:

1. Can they be walked together at this stage? I know the pup would only be able to go a short distance, but I'm wondering if this would help with bonding. 

2. Should we keep them separate until puppy is an adult? I'm a little concerned about the pup pestering Rumble, who mostly just wants to chill, so they haven't been together in the house yet, just in the same room but separated. 

3. Rumble has never shown any aggression towards other dogs, squirrels, cats, etc. Is there still a possibility something could trigger in his brain and he could attack/chase the puppy while he's small? Should we always have a muzzle on him while they interact, or will this teach Rumble that we don't trust him? 

4. Any advice you might have for me! 

 

Thanks!

I am introducing a new puppy to my almost 9 year old grey later this month.  I wound up getting a soft sided ex pen to provide the puppy with a comfortable place to be around my grey but not in his face all the time, I have it set up in the family room where we spend most of our time.  Jack can be in the same room with "Scout" but also have his own space.  Of course we will be working to integrate them and luckily have a very large fenced in yard for them to be supervised while they play.  I also have a crate for the puppy to sleep in at night next to my bed.  I was also lucky enough to take a week and half off from work after the puppy comes home to help set up a routine and schedule for Jack and Scout.  Let me know what works for you!!!  Good luck!

Also, I am planning on walking them together as soon as I get Scout. I will bring Jack on walks alone also as I want to give him some special attention but, again, will try to integrate them together as much as possible.  This approach has worked for me in the past and will adjust as needed.

That's a really good idea about the space inside a space thing. Currently half the living room is Rumble's (grey) and half the puppy's. I might put the puppy's crate in Rumble's "room" for a bit, so Rumble can interact as he wants to, maybe 10 mins a day or something? Rumble is generally good natured with the puppy, will wag his tail at him, but when the puppy gets a bit in his face he will do a polite low grumble (not quite a growl) as if to say "ok that's enough, GTFO now please", so I don't like to leave them together loose too long. Pup is ready to start walks soon, so I'd be interested to know how your walks work out!
