For those who know the difference an MBF Jack is the best kind of Jack 

In all things give thanks to God, he is the creator of all things.

After 20 years of me raising my lovely little jacks, I have decided to take a break. In more recent years I have raised a fair few litters and it just has become a bit all consuming. Time to step back and slow everything down and just enjoy my dogs. I will announce if and when any litters are coming, we will have litters now through Spring of 2024. 

Welcome to Madra Beag Farm

MBF has been home to the most delightful, sweet natured little Irish Jack Russells for 20 years, it has been a wonderful experience!

After many, many great years, due to changes in my life and family life I have decided to take a step back from raising MBF jacks. We will have a few litters through Spring of 2024, then only once in a while.

Failte and we hope you enjoy looking through our site.

I like to remember this Irish Proverb when it comes to raising my Irish Jacks.

'May you have the hindsight to know where you have been, the foresight to know where you are going, and the insight to know when you have gone too far.'

This is Waffles visiting his dad Rufus (in the background). He is my entire world! I grew up with Jack Russell’s and none were like my Waffles. Best dog ever! Susie Fitzpatrick

We often remark that we could have 10 Baxter's.

He's truly the easiest, funniest dog we have ever had.

All down to great breeding I think. 

Thank you. Alex & Betty. 


Toora and Rosie 5 yrs old, best girls. Everyone says wow I can’t believe they are so mellow for jack russells.

Scruffy is "perfect."  He does not bark. He is friendly to all people and with all dogs. He is reliable on long off-leash walks on the trails where we meet dogs, joggers and bicycles.  He stays at home, comes when he is called, is 98% housebroken....And of course, cute as a button.
Thank you!

It's the Stemmermann family wanting to thank you for the greatest dog ever. Skipper is just the best dog.

We didn't just get amazing family pets, we got the most beautiful, intelligent, loving family treasures with Blaze and Woody. MBF pups and Fiona are so phenomenal we will be welcoming a third little treasure soon .
