Mastiff: Breeder selection and lines

When choosing a Mastiff, verify the named records and the issuing scheme before relying on a breeder's description. Treat the record as background information, not proof of how this individual dog will respond. Ask for named tests, dates, scheme or laboratory, parent identity, and the written result; compare the record with the intended home routine. Verify the document with the issuing scheme or laboratory before treating it as evidence for a decision.

What to verify before choosing

Mastiff's recommended parent-club health tests is recorded as ['Patella Evaluation', 'Hip Evaluation', 'Elbow Evaluation', 'Cardiac Exam', 'Ophthalmologist Exam', 'Cystinuria DNA Test', 'Autoimmune Thyroiditis']. Here, that matters because it identifies a record to verify, not a diagnosis of the dog in front of you.

Read the record, not the promise

  1. Ask for named tests, dates, scheme or laboratory, parent identity, and the written result; compare the record with the intended home routine.
  2. Keep the recommended parent-club health tests in view (['Patella Evaluation', 'Hip Evaluation', 'Elbow Evaluation', 'Cardiac Exam', 'Ophthalmologist Exam', 'Cystinuria DNA Test', 'Autoimmune Thyroiditis']) and make the next step reversible, observable, and easy to stop.
  3. Verify the document with the issuing scheme or laboratory before treating it as evidence for a decision.

Walk away or pause if

Do not proceed on verbal assurances when required records are missing, unverifiable, or inconsistent.

Exercise: Bred to be guardians of 'hearth and home,' Mastiffs have comparatively low exercise requirements and can live happily in an apartment.

Training: Obedience training and early socialization are 'musts' for Mastiffs. Mastiffs learn quickly and want to please. However, the repetitions in a typical training class will quickly bore them, at which point they may lie down, snoring. Make eye contact with your Mastiff; they communicate a great deal with their eyes, and they are excellent at reading your…
