My deaf border collie girl is reactive when out and about, predominately when startled by people or dogs approaching with no warning. The bright yellow stands out, the padded harness can be adjusted to fit perfectly and helps to keep her under control. Absolutely recommend, especially in combination with the 'deaf dog' lead also from Friendly Dog collars.
Crystal just loves her new harness. She'll push her head through the collar as soon as it's held out to her.
