1f. What experience do you have with puppies and dogs? 

1g. Have you (or your significant other) ever rehomed an animal? ____  If yes - who, when, why? _______

1h.  Is everyone in your household enthused about getting a mastador puppy, is willing to put in the time and effort that it takes to train and raise a puppy, and agrees to the terms of this agreement? ________

1i.  Is anyone in your household allergic to dogs?  ____________________

2a.  You agree not to crate or kennel the puppy for extended periods of time. (Nap-times and Night-time crating while potty training is ok as long as you take the puppy out as needed for potty.)  

2b.  You also agree not to leave the puppy alone for more than a few hours each day.  ie - If you work outside the home - you either take the puppy with you, have puppy daycare, or you have a play area and another pet or person companion for your puppy. 

2c.  Please provide details of your schedule and the pups living area. 

3.  Mastadors are very social dogs, and puppies are babies that need regular companionship.  You agree that you will have another dog or have access to other dogs on a regular basis (at least 3 or more times a week) for "puppy play dates". (I recommend if you do not have another dog or only have an older dog, that you consider two puppies - I've personally found that raising 2 puppies at the same time is much much easier than just one & it is better for the puppies.)  A single furkid that is used to having other dogs in the family can make for a bored and lonely puppy.  

4.  Vet Info:  Name/Clinic/Address/Email/Tele:

4a:  List 3 References (Name/Address/Email/Tele/Relationship to you/How long known):

5.  Your puppy will live inside your home, as well as have regular access to outdoor exercise.  You pup will Not be chained or confined to an outdoor type kennel.  If you ever need to evacuate - you will take your pup with you.

6.  You will provide a high quality food (you will start your pup on LA All Life Stages Dog Food and wellness supplements & order the 40lb bag XL System, case of canned food, treats, ear care, & other supplies, from the provided links before getting your puppy) (offer 5-6 cups a day unless puppy is over weight - on L.A. they will likely eat much less (3-4 cups) unless going through a major growth spurt).   We offer an extended warranty for those who continue their pups on L.A.

7.  You agree that you have adequate income/resources to provide medical/vet/holistic care as needed.  You agree to activate the free 30 day health insurance for your puppy before, or at the time of, picking up your pup, or if delivery - at or before the time the driver picks up your pup.   (For CA residents a small fee applies.)  You agree to authorize me to activate said insurance (Ins is at no cost to you and no obligation - it will automatically drop after 30 days unless you pay to enroll.)  You agree to pay to continue the insurance or carry other insurance for your pup if you would not have the funds to cover any major accident, illness, injury, etc, or if any circumstance arises within the free trial period that would require additional vet expenses.

8. You agree that you will not use oral flea and tick preventatives (if you do use these products you understand all warranties are void and that many dogs are having very serious side effects including unexplained illness, seizures and death. Do a facebook search "Does Bravecto Nexguard Comfortis Simparica Trifexis & Others Do they kill Dogs" to find several groups that also include the other brands of oral flea and tick meds, as well as collars and spot-ons.)  Spot on meds can also be very dangerous causing severe side effects and even death.

9.  You agree that you will not use harsh training methods, regarless of the age of the puppy, that you are resposible for training, (oler puppies can take longer to adjust) and that if a behavior or training issue should arise that you are not able to resolve easily on your own, that you will seek the assistance of a reward/positive reinforcement based professional trainer or behaviorist.   

10.  You agree to socialize your puppy to other people, dogs, experiences, environments, & basic training, etc when you get your puppy through their 2nd year and as needed throughout their life.   We also recommend finding or creating a good puppy class.

If these circumstances were to happen, you agree to return the Mastador prior to whelping to my facility at your expense, (unless otherwise agreed, in writing, that you would have the capability of whelping and raising a litter - in which case you agree that pricing and marketing of said pups will be determined by me, with your full cooperation including requested information, photos, videos, etc, and that I am entitled to all proceeds from said litter.)  You would have the right to pickup your Mastador at your expense once the puppies are weaned.  You agree that all proceeds from the puppies soley belongs to me.  (If you do not cooperate or pay me the proceeds from the litter - Violation of the non-breeding clause will result in damages to me in the minimum amount of $12,000 per litter.)

12.  You have a written plan for the puppy if something should ever happen where you would no longer be able to care for the puppy, such as in the event of family tragedy or some other unforseen circumstance.

17.  We post photos and/or video at least every 7-14 days to individual puppy albums and/or our MastadorPuppies Facebook Page.  Photos and videos taken by us can be used by you for your personal use only.  Once you have reserved a puppy, all requests for additional photos and/or video, of reserved puppies, must be accompanied with payment.

Has the sweetest best personality
We have been breeding Mastadors for over 10 years now, and are the first Breeder of the  Mastador (aka English Mastador).  We are located on an 80 acre ranch by Hinckley, MN.   Our dogs live in the house with us as pets and also have access to 80 acres of fields, ponds and woods to explore.  Our adult dogs live in the house as pets and The puppies are raised in our home the entire time they are here with us,  not just the first 2-3 weeks like many breeders who "house raise" their pups.   Our puppies experience everyday household life and noises daily like the comings and goings of people and our other dogs, the TV, vacuum cleaner, blender, bug zapper, and other sounds and activities.  I am a stay at home puppy mamma and the puppies are played with and cuddled everyday.  Once our puppies are big enough to use the doggie door they have access to play outside, explore the yard, and to potty outside.  We also implement ENS for their first 2 weeks of life, and thereafter daily enrichment items and activities, Socialization, Puppy Culture, and starting at 2 weeks old the Misty Method of early potty training.  
Their parents are health tested for over 150 genetic diseases.  Your puppy will come with a great start on potty training, initial vet exam (our vet comes right to our home), regular deworming, lifetime breeder support, health guarantee, free 30 day puppy health insurance, microchip, optional vaccinations, exclusive facebook group just for our puppy families, birth certificate, IDCR registration info/application, Puppy Training &/or Fitness Booklet, Blanket, Harness/leash, swag bag with treats, toys, & more.

We are proud to be licensed and inspected by the Minnesota Board of Animal Health, 
and look forward to participating in the Minnesota Breeders Excellence Program.

We can Deliver door to door to ANYWHERE in the continental US or can meet you at the the Canadian Border; You can pick your puppy up in person by car, or you can Fly in to Minneapolis, rent a car to pick the puppy up, and take the puppy back as carry-on.

PHOTOS/VIDEO:  We post individual photos of reserved puppies to their individual albums approximately every 2 weeks with current weight in the description of the first photo for that week, and/or group videos to our facebook page.    We also post photos and videos fairly often to our Instagram.   If you would like extra photo session (6-8 photos) or video (1-2 minutes) featuring your puppy added to his/her album, you can request that using the Link below.

10 Years Experience Breeding Mastadors

A portion of the proceeds from each puppy will go towards nonprofit 501(c)(3) organizations helping dogs, and other pets and pet families in need.

So far donations have gone to:
People & Pets Together - 
Help pets whose people are going through financial hardship.  
Ruff Start Rescue - 
No kill, foster based, rescue based in MN
​The Animal Rescue Site - 
Funds to Animal Shelters across the United States.


Each puppy is priced individually. 
Prices are based on factors such as:  Gender, Color, Size, Conformation, Disposition, % of Mastiff to Lab, etc

In our 10+ years experience breeding Mastadors, we've found that offering a range of prices is the best way for everyone to find loving furever homes while allowing us to cater to a range of different budgets.  
Some Colors (and the bigger more mastiffy pups) are harder to come by, or may just be higher in demand. 
 The rarer/harder to find colors tend to be what I get the most requests for (Fawn/Sable/Apricot/Brindles).   
Other colors are much more frequent (&/or are in lower demand) so we ask a lower price for these pups.  


We track the pups weights and also follow up with some of our past puppies - 
so that I can give you a better idea of what range their estimated adult weight will be.

There can be a huge size range among our Mastadors - even pups from the same litter.  
Anywhere from 70 pounds on up to 170 pounds. 
Our averages for the girls tend to fall in the 110-130 range and for the boys is in the 125-145 range
