Trying to get your new corgi to interact with other dogs is not hard. It’s training them to BEHAVE properly that can difficult if the other dogs are different breeds than corgis. Dogs are instinctively natural pack animals. Having 3 or more dogs can be especially dangerous if some of the dogs are not corgis. No matter what size they are, they will initiate a rank system among themselves and decide who the pack leader is.

If you already have 3 or more dogs of different breeds and then decide to bring a new corgi into the household, it is likely that all of the dogs will gang up against your new corgi and attempt to dominate him. If they succeed, which is likely because Welsh Corgis are a small breed, then your new corgi can be traumatized for life. Although corgis have a pleasant disposition, your new one will treat all new dogs in your house thereafter in a ferocious way, much like how he was treated when he arrived.

Dogs are known for their territorial “ownership”. Much like wolves, they form a pack and do whatever they need to or want to in order to protect their territory. A lot of the reason why they’re dominant over the household against new dogs is that they have to adjust their entire rank every time someone new comes in.

The trick is to make sure you, as the human, are the pack leader. They need to respect you or else they will just do whatever they want to. You have to show them that you are the boss. It is perfectly possible for your dogs to love you without respecting you.

Another approach is to get some type of collar. A prong collar – one of those metal collars with spikes all around it – is not the kind you want. This’ll only aggravate them more. You might one to try out a shock collar, but some people just don’t want to do that (I personally would never use one because I consider them to constitute animal abuse).

Alternatively, you could purchase a muzzle for each dog, at least the bigger ones who are not corgis. This should be used only when you are unsure of what the dog is going to do or how multiple dogs will interact together. A muzzle may be good when first getting a new corgi, but should be taken off before too long. I’ve never seen a corgi that needed to be muzzled so if a muzzle is used, it should be used sparingly and only with a larger breed dog that might threaten your new corgi.

If you want to go through the trouble, you could setup several large sections of fenced in area of your yard so that your corgi can run around and have more room to relax. They can still smell each other trough the gate, but they won’t be too aggressive because (1) they can’t really fight each other if they’re separated, and (2) they have more room to not be so picky about territory. In any case, it’s not very fun having a dog that is restrained. The whole point of having a corgi is to love it, so make these kinds of decisions wisely.

Aside from getting new gadgets to restrain dogs, just try to get dogs of the same breed, i.e., get all Pembroke Corgis or Cardigan Corgis.
