How do DNA tests help with mixed-breed adoption?

How breed DNA tests can support adoption decisions

DNA tests for dogs can reveal breed influences and sometimes uncover inherited health risks. For adopters, these tests offer curiosity-driven insights, possible explanations for temperament or size, and guidance for preventive care. However, they’re not definitive predictors of behavior.

What DNA tests provide:

• Breed composition estimates and likely ancestry percentages.
• Approximate size and coat trait expectations based on breed mixes.
• Potential breed-linked health risk information (varies by test and evidence base).

Limitations to keep in mind:

• Results are probabilistic, especially with complex mixes; small breed contributions may be missed.
• Temperament is shaped by environment and training as much or more than breed genes.
• Not all genetic health predispositions are fully understood or clinically actionable.

Use results as one data point: combine them with shelter notes, vet exams, and your observations. If a test flags health risks, discuss screening or preventive steps with your veterinarian. Ultimately, DNA tests can enhance your understanding but shouldn’t be the sole reason to accept or reject a potential companion.
