Frequently Asked Questions
How do I measure my toy dog for a harness?
Measure chest girth at the widest part behind the front legs and the neck where a collar would sit. Compare to the manufacturer size chart and choose a size that allows two fingers between the strap and skin for a snug, secure fit. If between sizes, size down for small breeds prone to escape but only if adjustments still allow comfortable breathing.
Will the tactical style be too heavy for a Chihuahua or toy poodle?
Tactical models include reinforced panels and handles that add durability but can slightly increase bulk. For the tiniest dogs prioritize XS-specific models and look for mostly mesh panels with minimal heavy nylon. Many small-breed owners report the ONETIGRIS XS fits well when adjusted properly.
How should I care for a mesh harness to prevent smells or mildew?
Hand or machine wash on a gentle cycle per label instructions, rinse thoroughly, and air-dry fully before storage. Mesh dries faster than padded foam and resists mildew when kept clean; avoid leaving damp harnesses in closed bags or trunks.
