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.

Welcome to Madra Beag Farm

MBF has been home to the most delightful, sweet natured, little Irish Jack Russells for over 20 years, I am so grateful for that.

MBF farm has developed and grown over the years, I feel incredibly fortunate to have been able to follow my childhood dreams and do what I really love.

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.'

I started raising my jacks as a stay at home Mum, just a litter once or twice a year. Over the years MBF grew, in the last 10 years I have been mad busy with raising dogs and I am realizing it is time to slow things down a bit. I considered retiring altogether but I can't, MBF is part of who I am. Instead I will just be enjoying my Jacks and having a litter once or twice a year again.
As always, we will announce all litter plans in advance.

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 .
