What this means for your Xoloitzcuintle (Standard)
Skin protection from sun and cold is a particular consideration for hairless individuals, alongside dental issues that are more common in hairless lines. The breed is otherwise generally considered hardy, having developed largely through natural selection over centuries.
Sun cream formulated for dogs and a coat for cold weather can help protect a hairless Xoloitzcuintle's skin, which lacks the natural protection a coat would normally provide.
