Does Your Dog’s coat Get Warmer and More Humid During a Walk?

PAWEVIE JOURNAL · BEHIND THE PRODUCT

Before a raincoat becomes part of a dog's wardrobe, we want to understand what happens underneath it. Our internal tests look at moisture and temperature alongside the checks needed for rain protection.

We take our time bringing new clothing to Pawevie. A raincoat needs more than a promising fabric description: the material, fit and openings all deserve attention. In the results below, our revised sample recorded lower local humidity and temperature than the comparison raincoat under the stated conditions.

Looking at the space beneath the raincoat

Our evaluation covers three stages: fabric testing, wear testing in a dry environment, and simulated rainfall on a heated, humidified dog model. Each answers a different question. Fabric checks examine properties such as resistance to water pressure and water-vapour transfer. Wear tests explore the local conditions beneath clothing. Model tests help examine seams and openings under repeatable rainfall.

The wear-test protocol describes 12 healthy adult dogs with short and long coats, randomized test order, owner consent and review by a professional experienced in canine exercise physiology. Three conditions were compared: no raincoat, a commercially available comparison raincoat, and a revised Pawevie sample. The no-raincoat condition served only as a dry-environment baseline.

What happened during gentle activity

At an ambient temperature of 20°C and 60% relative humidity, the sequence comprised 10 minutes at rest, 10 minutes of gentle walking and 10 minutes of recovery. Local measurements were taken at the side of the chest, between the fur and garment where a garment was worn.

Relative humidity at start, end of walking and end of recovery: no raincoat 61, 67, 62 percent; comparison raincoat 61, 84, 77; Pawevie 61, 75, 68.
Three reported checkpoints; the source does not provide a continuous dry-test time series.

At the end of walking, the Pawevie sample recorded 75% relative humidity, compared with 84% for the comparison raincoat: a difference of 9 percentage points. After recovery, the readings were 68% and 77%, respectively. Both garments remained above the no-raincoat baseline.

Local conditions at the end of walking
Measurement No raincoat Comparison Pawevie
Relative humidity 67% 84% 75%
Local temperature 24.0°C 27.2°C 25.8°C
Absolute humidity* 14.6 g/m³ 21.8 g/m³ 18.1 g/m³

*Calculated values as reported in the internal summary. Local temperature is not core body temperature.

The Pawevie reading was 1.4°C lower than the comparison garment. Together, these observations support a lower local heat and humidity load in this test.

Testing in simulated rain

The rainfall stage used a heated, humidified dog model rather than live dogs. Ambient conditions were 15°C and 85% relative humidity, with rainfall at 5 mm per hour for 30 minutes. The two sample garments had the same coverage and main cut, while the Pawevie sample used the more moisture-permeable fabric. Heat and moisture inputs and spray conditions were held consistent.

Simulated rain internal humidity at 0 to 30 minutes in 5-minute intervals: comparison 85,88,91,94,96,95,94 percent; Pawevie 85,86,88,90,91,90,89 percent.
Heated, humidified dog model · 15°C ambient · 85% ambient RH · 5 mm/h simulated rain.

The comparison raincoat reached a recorded high of 96% relative humidity; the Pawevie sample reached 91%. At 30 minutes, their readings were 94% and 89%, a difference of 5 percentage points. The Pawevie sample showed lower internal relative humidity after the shared starting point throughout the reported observations.

Checking rain protection separately

The rainfall protocol includes sensors at the chest, back, belly and hind leg, plus pre-weighed absorbent pads near potential entry points. It also describes a compatible tracer to help distinguish incoming rainwater from internally formed moisture. This matters because droplets alone do not reveal where water came from.

The humidity results shown here do not quantify leakage or condensation. Those conclusions require the pad-weight, tracer and surface-temperature results, which are not included in this summary. Our aim is to improve moisture management while checking that rain protection is maintained.

What these results mean for everyday walks

These observations help us evaluate the revised sample and guide further product decisions. They are specific to the test conditions, garments and animals described; fit, coat type, weather and activity can change the conditions beneath a raincoat.

About the data: The results presented here are from Pawevie’s internal testing and are not an independent third-party certification.

This article describes only the observed differences. It does not claim that these differences are statistically significant or establish that Pawevie rainwear is superior to all other raincoats on the market.

For us, choosing with care means looking beyond the outside of a garment. We want to understand the details that shape how it performs, and be clear about what each test can tell us.
