Methodology
How SizeMyPet creates sizing guidance.
Recommendations are cautious planning estimates. They help shoppers measure better, not replace brand charts or professional instructions.
Breed Estimates
Breed pages use typical adult weight ranges, size categories, and known body-shape traits such as deep chest, short muzzle, long back, or dense coat. Individual measurements matter more than breed name.
Expected Measurement Estimates
Expected height, body length, chest girth, neck circumference, and crate-length ranges are planning estimates based on size category, breed weight range, and body-shape cautions. They are used to help readers narrow searches before measuring the individual dog.
Measurement-Based Results
Calculator results prioritize the measurements that matter most for each product type: crates use length and height, harnesses and life jackets use chest girth, collars use neck circumference, cones use neck and snout length, and beds use body length.
Source Hierarchy
The strongest guidance comes from direct measurements, manufacturer size charts, veterinary or humane-society guidance for safety and handling topics, and reader corrections with supporting details. General breed data is used only as a starting point.
Conservative Notes
The site favors cautious notes when a product affects safety, recovery, containment, buoyancy, or comfort. Life jackets, recovery cones, giant-breed gear, and puppy sizing include extra reminders.
Product Picks
Product pick cards are organized by fit criteria such as adjustability, support, hardware strength, washability, and intended use. Affiliate relationships may exist, but product links should still be compared against brand size charts before buying.
Limits
SizeMyPet does not test every product, diagnose medical needs, provide veterinary advice, or guarantee fit. For post-surgery, safety, flotation, or restraint products, manufacturer and veterinarian instructions come first.
Review And Updates
Pages are reviewed when product categories change, new product links are added, site methodology changes, or readers report corrections. Important policy and legal pages show a visible last-updated date.
Corrections
Sizing data can be improved. If you find a mismatch, send the breed, product type, measurements, product brand, and chart or fit issue through the contact page.
