Jack is two years old, and we would like to add another Corgi to our household. We would be getting a female puppy. We are not sure on timing; either this summer or next spring, depending on litter availability (we really hope to use the same breeder we did last time, as we are very happy with Jack).
Jack is a happy-go-lucky guy who has never once gotten in a squabble with another dog, and has no serious behavior issues, so I'm pretty sure he'll be good. We've had another dog in the house visiting, and he was thrilled for the company. I understand how to introduce a puppy to the resident dog. But I have some questions on making sure they continue to get along after the introductions, and I get conflicting info online. Some sources say you should let them sort out their own pecking order, while others say the opposite: you should step in at any sign of growling or air-snapping. Here are my questions:
1) I know to feed them apart to avoid food aggression, but what about toys? Should they be expected to share everything? Or should they each have their own toys? Puppies have special puppy toys that would be kept in pup's confined area, but I'm more concerned about when they get older.
2) When should I step in if there is a bit of a dust-up? Is it ok to allow the occasional "back off"growl between dogs? Or should that be stopped outright? I know out-and-out fighting shouldn't be tolerated, of course, but I am of course hopeful it would never come to that.
3) Should I continue to take both dogs out separately at times so they don't get overly dependent on each other, or is it ok to pretty much take them both out together? (I'm thinking I would want them to get used to going places on their own; Jack for instance does Therapy Dog work, and it would be a couple years before a pup would reach that level of training, if she even has a suitable disposition for it).
4) I have seen it recommended that you ALWAYS feed, treat, and pet the same dog (usually the older one) first in order to not upset the natural order. Is this a good idea?
5) The puppy would be in a round pen during the day when we are not home, and crated at night (this is the method we used with Jack, and it worked well). Jack now has the run of the house. Would it be okay to allow Jack into the room with the crated/penned puppy when no one is home (they could then interact through the wire mesh)? Or would it be best to use baby gates to keep Jack away from that room altogether when no one is around to supervise? (I would make sure they liked each other before I would consider letting him near her alone, even through the pen or crate).
6) Finally, a minor issue, is it ok to use the same brushes on both dogs (assuming they don't have any diseases), or should they have separate brushes. I'm sure they'll be on top of each other all the time, so I would think any contagious things they might pick up would eventually spread from dog to dog anyway, shared brush or not.
I know that is a lot of questions for one discussion, but I know we have several breeders/rescuers here who successfully maintain multi-dog households all the time, so I am sure you all have great tips!
Thanks in advance.
