Well I'm sure I'm very biased but I'd say go for the cardigan! Did you do a breeder search on the club's website? It looks like there are quite a few breeders around your area. There are a couple in Ohio that are around 3 hours from you too I think.
Just one word of warning - when I started looking for a cardi 2 of the 3 breeders I contacted were extremely slow responding to my email (like a month+...). Hopefully you won't have the same experience, but it might be worth it just to call some of them if you want a quick reply.
There are plenty of Pembroke breeders in PA and Ohio, but most of them don't have websites.
www.pwcca.org, click on breeder referral, search by state.
Hi Krystal, it all really depends on Moose, his personality, how submissive / dominant...etc. Some corgis do very well when they are out meeting other dogs on neutral ground, but when it comes to adding a new member on home turf? Totally different story. Many corgis are perfectly fine on their own, it is often the owner who thinks adding a companion is a good idea. Read this FAQ.
Since we've all experienced the joy of dog ownership, I am not going to bore you with the positive side. It is not my intention to discourage you from getting another dog, I just want to present you things that often get overlooked. Do an honest evaluation of you and your fiancee's financial, living and job health. What happens when one of you loose a job for 1 year? Do you have 6 months worth of savings to carry you through? We've had members here who have lost their jobs, homes, married / divorced, newborn with allergies...etc and they had to make the hard choice of letting their dogs go. I personally have fostered many corgis because of those reasons. No one likes to think about those things, but they are very real.
The economy plays a big role, when you add another dog to the family, you are looking at 2K+ for the first year (1 dog), 2 emergency vet visits will bump that up to 4K easily. Getting married is stressful and costly, when you bring two dogs on the road, it's $25-45 per dog / night + your human hotel bill.
As far as Cardigan goes, there is currently an excess inventory of Cardigan on the East coast, there are 22 litters of Cardigan puppies from Florida to Ontario. One show breeder that I talked to recently is having a tough time placing hers, so there are a LOT to choose from.
I'm going to give you a list of dogs that my corgis have "LIVED" in the same house for a few days.
Again, every corgi is different and these are the dogs that my corgis have done well with.
Here's a list of dogs that we "MEET" on a daily basis and have done well
Here's a list of dogs that my (racist) corgis met and CANNOT get along
Chow Chow - my neighbour have 2 big fluffy ones, they are very well trained chow, but my Mocha is scared of them and would not stop growling and barking, we work with our neighbour every chance we get but so far not successful.
Jack Russell - 1 block away from us, always bark through the window or across the street, its the owner, not the dog or the breed.
