Cassie & Me Welcome

Sierras' has been involved with the TM for nearly 35 years. We are willing to help others with evaluations as well as mentoring. Our dogs are working flock guardians on a 114 acre farm and protect our poultry and livestock from predation, four legged and winged.

We show AKC, owner-handle our own dogs to AKC championships as well as having produced AKC champions WHEN we determine we need to breed for authentic type for the future of the working Tibetan Mastiff.

Our working dogs are also our AKC champions so one does not need to produce two different types to achieve property protection and show wins.

We Have Dogs Available For Adoption!

We have adult TMs ranging from 1 year to 5 years available for adoption, male and female, all are sterilized. Black/tan and gold. More information here.

Our new website is a work in progress, visit us often for changes and updates to our new site.



When GOD had made the earth and sky
The flowers and the trees
He then made all the animals
And all the birds and bees.
And when His work was finished
Not one was quite the same
He said I’ll walk this earth of mine
And give each one a name.
And so He traveled land and sea
And everywhere He went
A little creature followed Him
Until it’s strength was spent.
When all were named upon the earth
And in the sky and sea
The little creature said “Dear Lord,
there’s not one left for me”.
The Father smiled and softly said,
“I’ve left you to the end…
I’ve turned my own name back to front
And called you DOG my friend”.
