Tip #1: Facebook is your Friend. Facebook groups are really revolutionary in helping people find anything they are looking for . . . whether it's a couch, baby toys, or any pet animal. Almost everyone in the US uses Facebook, so you're bound to find at least one rabbit breeder through these Facebook groups near you.
There are so many Facebook groups available to help you find a rabbit. I'm going to list several below. These are all oriented towards anyone in the US, Canada and beyond, but I'm sure there are several for whatever breed you want just within your state. Most of the ones I'm listing below are exclusively Holland Lops, but I've listed some that are all breeds as well.
Holland Lop Showroom
Holland Lop Rabbitry Websites
District 1 ARBA
Rabbitry Websites/FB Pages for All Breeds in the US
If you aren't into Facebook, there are still plenty of ways you can find a breeder near you with stock for sale.
Tip #2: ARBA Breeders Directory. There are THOUSANDS of breeders listed on this page, since it's open to anyone who is a member of the ARBA and wants to pay for the service of having their rabbitry listed. There's bound to be at least one breeder near you that is raising the breed you're interested in! Click HERE to hop right to that page.
Tip #3: Check your Breed's Club. This way, you will know that all these breeders are committed to the breed you are interested in, because their membership to that club is active and updated. But, you will need to do some digging around; I don't know every club for every breed, and so you will probably have to search for them on Google.
Tip #4: Breed Sweepstakes. On national breed clubs there will usually be a sweepstakes page. Sweepstakes are earned at shows when a rabbit wins a high placement. So the top breeders that win the most often will have the most sweepstakes points. If you're interested in raising show rabbits, choosing the highest placing breeder near you is one of the best options.
Tip #5: If All Else Fails, Transport is Always an Option. If you find a breeder you like and they have rabbits you are interested in, but they are too far away for you to go on a road trip yourself, there are some people that make it their job to transport rabbits all over the country. Of course, there is a fee that comes with it, usually around $15 per rabbit, which is pretty cheap considering how much it would be for you to go on a road trip yourself. Then, there is also the occasional breeder travelling across the state or across the country for a rabbit show that would be willing to transport rabbits for a small fee. After all, it is a nice way to help with gas prices.
