Meet the breeder
I'm Dannie R., the breeder behind Riot River Mastiffs located in Riddle, OR. This program is focused on longevity and workability in the modern Mastiff. I currently have a few crossbreeds, as it is still early in the program. I have so far produced stable and confident, relatively versatile dogs. Mainly hard hitting workers, a few therapy dogs and SDs as well. Q&A is welcome.
Q. & A. with Dannie
Why did you start breeding?
My mom. My family has always been involved with animals and breeding. It wasn't until I was older did I find that I was really interested in just learning about the world and genetics. My first litter as a young child, when I was hooked. And I was good at it. My mother was my mentor. She chose the matriarch for this program. Madelyne. And I owe that dog so many more of my lives.What makes your program special?
I am not sure if we're special, I just care deeply about how long such tremendous creatures get to be around. And the quality of the life they live, as well as the quality of their golden years. It gets disheartening sometimes. Breeding is hard work. If I can make a small change and bring hope to others, while also keeping these guys healthy, then I have some my part and then some.What are the different breed coat colors in your program?
Our puppies include black and brindle. Colors will vary depending on the parent dogs.Where do your breeding dogs live?
They live in my home and guardian homes.

Jumanji, mom
Perro de Presa Canario
About Jumanji
Jumanji is out of Spartan Presa Canario Kennel (Sergio Vergara) and was unfortunately not treated the best by her first placement, who later ghosted her breeder Which is how I ended up with her! She absolutely lives up to her name. She is a little pocket rocket at just twenty four inches TtW, and eighty five pounds. She knows who she likes, and what she wants She is Presa to a tee. Endlessly affectionate, a little hard headed, and absolutely put all my patience to the test. A true guardian. Proven on small game, and on man.
Uploaded health tests
Hyperuricosuria (HUU), Multifocal Retinopathy 1 (CMR1).Valkyrie Mae, mom
Bullmastiff
About Valkyrie Mae
V is a Bullmastiff x Mastiff outcross. Partnered with Project Guerrero Bullmastiff. A true gem of a dog. I value exceptional communicators skills, and V dog here has that in troves. Happy go lucky, always down to play, work, or cuddle, she is a dog who goes from zero to two hundred in an instant. She has an injury as a pup that caused her to have partial vision in one eye, but you'd never know. She is an all around stable, well rounded dog, who has taken any challenges she's been faced with, we completely devoured them. Proven on man and small game.

Mastiff
About Trigger
Trigger is off my foundation female, Madelyne. He is majority Mastiff, with a small bit of Neapolitan. Defensively driven, and very owner oriented. He's very intelligent, and has a very goofy streak with his family. Medium prey drive, and biddable.
