Look inside

Real pages from the Mastiff guide. Chapters marked Personalized are written for your home after you answer a few questions.

Chapter 1

Before you begin

Three kinds of health care come up when you talk to Mastiff breeders. They are often mixed together, but they answer very different questions.

Health screeningExaminations of a puppy's parents for inherited problems that can be seen or measured, such as hip and elbow X-rays, eye exams and heart exams.
Genetic testingLaboratory DNA tests of the parents for specific gene mutations that cause disease. A DNA test can find a mutation years before any sign appears.
Puppy health and veterinary careThe care the puppy itself receives: a veterinary check-up, first vaccinations, deworming and often a microchip.

Recommended screenings

Hip evaluation

An X-ray of the hips to look for hip dysplasia, where the ball and socket of the joint do not fit together properly.

Hip dysplasia is partly inherited. It can cause pain, arthritis and lameness, and surgery to correct it is expensive.

Excellent, Good or Fair: Normal hips. All three pass.
Borderline: Unclear. OFA recommends repeating the X-ray about six months later.
Mild, Moderate or Severe: Hip dysplasia was found.
PennHIP distraction index: A number between 0 and 1. Lower means tighter, healthier hips. Ask where the result falls against the breed average.

Questions

What makes it personalized?

Seven quick questions about your home and household write your guide. If you take the free home-fit check first, it answers them, and your guide opens as soon as you pay. Inside the guide, a few more questions about your schedule, the activities you have in mind, your province and dogs you've had add their own sections. Your guide uses your answers to suggest enrichment ideas, write your breed match, plan for time alone and the activities you love, cover your province's climate and local rules, compare the breed with dogs you've had, and add questions for your household. You can update your answers any time and your guide updates with them.

Do breeders see my answers?

No. Your answers are only used to personalize your guide.

Can I keep a copy?

Yes. Read it online in your Paction account whenever you like, or download a printable PDF.

I am considering more than one breed.

Each guide covers one breed. Once you own one, every additional breed's guide is 8.99 CAD and ends with a bonus chapter comparing the breeds side by side, including how each one fits your home. Use the breed picker at the top of this page to preview another breed's guide.

Can I buy a guide if I live outside Canada?

Not yet. Personalized guides are only available to Canadian residents, and checkout needs a card issued in Canada with a Canadian billing address. The advice for your province is written for Canadian provinces and territories.

Is this veterinary advice?

No. It is general information to help you prepare for conversations with breeders. Talk to your veterinarian about your puppy’s health.
