Hi Catherine, I am also looking for a reputable breeder in New England... I see you didn't get any responses here, but I figured I'd ask if you found recommendations elsewhere that you could share? Thank you!
Hello!! I did a lot of research and it's hard to know what is right. It was helpful to go on Bernese Mountain Dog Club of America and search breeders. Once you have found a breeder, go on bernergard.org and search the breeder. It will show results of their dogs tested for genetic disorders. Megan Tavish was very good but more expensive because she literally does everything you could ask for. She's great. However we went with best bernese in nh. She was not on these websites but I had a good feeling about her. She let me call her vets too. Check out Facebook pages for reviews too. I found a lot from that. I checked out Linda from Fairport NY she had a mix of great reviews and some very concerning ones so I ended up not going with her. Good luck !! Hopefully this helps!
