Frequently Asked Questions
How do I measure my dog for these vests?
Measure your dog’s girth by wrapping a flexible tape behind the front legs around the widest part of the rib cage. Use that number to select the size; if between sizes, choose the larger size for comfort and better airflow.
Will mesh harnesses help prevent odor in humid climates?
Mesh and quick-drying materials help moisture evaporate faster, which reduces the conditions that cause odor. Regular washing and thorough drying after humid or wet outings is still important to keep the harness smelling fresh.
Are vest-style harnesses safe for dogs that pull?
Vest-style harnesses distribute pressure across the chest and are generally safer for reducing neck strain. However, if your dog pulls strongly you should select a harness with reinforced hardware or consider training tools to address pulling, since lightweight mesh vests are not designed for heavy-duty restraint.
