Hi Ellie, welcome to the forum! Your Remmington is a cutie pie!
I am in California, and I would be happy to help you find out what testing is required for stud dogs and to give you pointers...but you might not find someone wanting to use Remmington...not because he isn't a great dog...but because he is black. Black puppies are very hard to sell (believe me, I have bred them for years now)...they are gorgeous, but not hightly sought after...and there are so many black puppies out there that the market is tough. So, you are starting out with a few strikes against breeding...
There are lots of things to consider too...like, do you have breeding rights for Remmington? Most reputable breeders only sell puppies with a strict spay/neuter contract and unless you paid quite a bit more for your dog, it is unlikely that you bought breeding rights...you might want to check with your breeder.
Finally, it is so important that we breed for good health, along with the wonderful temperament and personality that Remington has...and genetic faults can be carried even though they are not showing up in the dog. So, good breeders do a battery of tests to rule out genetic faults. Breeders with female dogs test their girls and won't use males that are not tested. So there are a few things that you need to invest in before you breed Remmington.
He is a beautiful boy and his coat is a lovely F1 coat...breeding him to a very curly F1B or Poodle would be the best.
I wrote a few articles for this forum, one deals with how to become a good breeder...even though you have the male and not female, you might want to take a look at the things that good breeders consider before breeding their dogs:

Please let me know if I can help you with your questions. Best wishes...and wheter or not you decide to breed Remmington, I hope that you will continue to enjoy this forum!
