A Conversão Real

Regra dos 7 é falsa. 1 ano ≈ 15 humanos. 2 ≈ 24. Depois: 4-5/ano. Cachorros grandes envelhecem mais rápido. Dogue Alemão de 7: geriátrico. Pinscher de 7: auge.

Expectativa de Vida

Pequenas: 12-16 anos. Médias: 10-14. Grandes: 10-13. Gigantes: 6-10. SRDs (vira-latas) vivem 1-2 anos a mais que raças puras de mesmo porte.
