How the puppy weight predictor works
This predictor uses growth milestone data from Salt et al. (2017), published in Veterinary Record, which tracked the weight development of dogs across five size categories from birth to adulthood. By comparing your puppy's current weight against the expected growth percentage for their age and size category, we estimate their adult weight range.
Factors that affect adult weight
Genetics play the largest role, but nutrition, neutering status, and overall health also influence growth rate. Puppies fed excessive calories during rapid growth phases may exceed their genetic weight potential, while underfed puppies may not reach it. Large and giant breeds grow more slowly than toy and small breeds, reaching full size at 18–24 months rather than 10–12 months.

Tibetan Mastiff Health & Weight Management
Tibetan Mastiffs are ancient guardian dogs from the Himalayan plateau, bred to protect monasteries, livestock, and nomadic camps from snow leopards and wolves at extreme altitudes. They are enormous, heavily coated dogs weighing 80–160 lbs with an independent, aloof temperament. Their giant frame predisposes them to hip and elbow dysplasia, hypothyroidism, and inherited neuropathy. Their massive double coat makes it extremely easy for weight gain to go unnoticed — by the time visual cues appear, the dog may already be significantly overweight, worsening every orthopedic and metabolic condition.
Exercise: Tibetan Mastiffs need 30–45 minutes of moderate daily exercise. They are not high-energy athletes — they are guardians that patrol at their own pace. Evening walks in cooler temperatures suit them best, as their thick coat makes them prone to overheating. Avoid over-exercising puppies to protect developing joints. Mental stimulation through property patrol and environmental enrichment is more satisfying for them than forced running.
Feeding tips: Feed two measured meals daily using a giant-breed formula. Tibetan Mastiffs have a slower metabolism than many breeds of similar size — they require fewer calories per pound than expected. Portion control is critical. Avoid elevated feeders and strenuous activity around meals to reduce GDV risk. Their thick coat demands regular body condition checks by feel, not sight.
Keeping your Tibetan Mastiff at a healthy 80–160 lbs (36–73 kg) preserves joint function and metabolic health. Use PawScale's calorie calculator for Tibetan Mastiffs to manage daily intake, check body condition with our BCS assessment tool, and build a balanced meal plan with the feeding guide.

A typical adult Tibetan Mastiff weighing 55 kg needs approximately 2247–2808 kcal per day, depending on activity level and whether they are neutered. Use our breed-specific calculator above for an exact number based on your dog's details.
Is my Tibetan Mastiff overweight?
59% of dogs are overweight, and most owners cannot tell just by looking. Check your Tibetan Mastiff's Body Condition Score (BCS) — if you can't easily feel their ribs or they have no visible waist from above, they may be overweight. Take our free 2-minute BCS assessment above to find out.
When does a Tibetan Mastiff reach full adult weight?
Tibetan Mastiff puppies reach 50% of their adult weight by 8–12 months and typically reach full adult weight by 18–24 months, according to AKC growth guidelines. Small breeds mature faster than large breeds.
What size crate does a Tibetan Mastiff need?
A Tibetan Mastiff typically needs a 48-inch crate based on breed size. Use PawScale's free crate size calculator for a personalized recommendation.
