Walk through the house as if the adult dog already lived there
Before choosing a Mastiff, check the route from its resting area to the outside and from the front door to your vehicle. Where are the slippery turns, narrow passages and steps? What would happen if the dog could no longer climb into the car independently? Ask your veterinarian about an appropriate assistance plan and practice any equipment before it becomes necessary. This is a more useful preparation than assuming a gentle temperament makes size irrelevant. AKC emphasizes early socialization and gentle, positive training for this powerful breed. Teach manageable greetings and comfortable handling while the puppy is small, then keep those routines consistent as it grows. Include an adult-sized resting place, drool cleanup and access for brushing in the household plan; a short coat does not mean the dog takes up little space or creates little work.[1]
Make a bloat emergency plan before you need it
Gastric dilatation-volvulus, or GDV, is a rapidly progressing emergency. ACVS describes warning signs including unsuccessful retching, an enlarging abdomen, anxiety and drooling; weakness or collapse may follow. Suspected GDV needs immediate veterinary attention, not observation until the next meal. Because a Mastiff may normally drool, pay attention to a sudden change alongside distress or retching rather than treating drool alone as a diagnosis. Save the emergency hospital’s number and route, and decide who can help transport this large dog. Tell a sitter where those details are kept. This preparation is not a way to diagnose the problem at home; it is a way to avoid losing time when urgent assessment is needed.[2]
Compare the health statement with the actual records
The Mastiff Club of America’s January 2025 statement lists hip, elbow, eye and cardiac evaluations for its CHIC requirements and recommends a broader set of screening for breeding dogs. Its additional recommendations include thyroid and patellar evaluations and named DNA tests. Ask for records for both parents, linked to permanent identification, instead of accepting “vet checked” as the equivalent of the listed evaluations. Put the test name, date, result and dog identity together and note what is missing. The statement distinguishes a cystinuria-associated DNA marker from annual urine testing for intact males; these are not interchangeable descriptions of one test. Bring the records to your veterinarian to discuss their relevance to the dog you are considering. Screening information supports a decision but cannot predict every future illness or replace care for the individual.[3]
Frequently asked questions
Should I wait if my Mastiff is trying to vomit but nothing comes up?
No. Unproductive retching, especially with abdominal enlargement or distress, can indicate GDV and needs immediate veterinary attention. Contact an emergency veterinarian and arrange transport; do not wait for every possible sign to appear.
Source [1]Does a calm Mastiff still need training for greetings and handling?
Yes. Quiet behavior does not remove the practical consequences of an adult Mastiff’s size and strength. Build positive, consistent routines while young and check that every caregiver can manage them safely.
Source [2]Is “the parents were vet checked” enough detail about Mastiff health screening?
No. Ask which named evaluations were performed, when, and with what results. The MCOA’s January 2025 statement distinguishes its CHIC evaluation list from broader screening recommendations; a general examination does not document each of those tests.
