A dog tank top is the coolest thing a dog can wear: sleeveless, light, and open under the front legs so there is nothing to rub when the dog runs.

Why sleeveless

Leg openings are where most dog clothing causes friction. A tank top removes them, which suits active dogs and hot days. It is a style and light sun-cover piece rather than a warmth layer.

Fit

Measure chest girth behind the front legs. The armholes should be wide enough that the dog can stretch fully without the edge cutting in. Light colours stay cooler in sun.

Frequently asked questions

Do tank tops keep dogs cool?

They add very little heat and some sun cover. On very hot days shade and water matter far more than clothing.
