- Adults (1-7 years): Annual wellness exam, vaccinations, heartworm test, dental cleaning, screening for Lymphoma
- Seniors (7+ years): Twice-yearly exams, blood work, urinalysis, and monitoring for Lymphoma and Hip Dysplasia
Life Stage Health Guide
Bullmastiff life stages and what to expect over 7–9 years:
- Puppy (0-12 months): Socialization window, house training, vaccination series, growth toward 130 lbs
- Adolescent (1-2 years): Boundary testing, Responds to consistent, positive training but can be stubborn; early socialization is critical because a poorly socialized 130-pound guardian dog is a liability., filling out to 24–27 inches
- Prime adult (2-7 years): Peak energy (2/5), established routine, preventive care including Lymphoma screening
- Senior (7+ years): Activity adjustment, monitoring for Lymphoma, enhanced veterinary monitoring
