Plain-English summary
A group of dogs with itchy skin due to dermatitis was treated with a special soap containing linoleic acid (LA) mixed with ultrapure soft water. This combination helped reduce the number of harmful bacteria on their skin, which can worsen skin problems. After using the soap, the dogs showed improvement in their skin condition and less itching. This suggests that using LA soap in ultrapure soft water can be an effective way to help dogs suffering from dermatitis.

Abstract
AIMS: Skin colonization of Staphylococcus spp. critically affects the severity of dermatitis in humans and animals. We examined different types of fatty acid salts for their antibacterial activity against Staphylococcus spp. when used in ultrapure soft water (UPSW). We also evaluated their therapeutic effect on a spontaneous canine model of dermatitis. METHODS AND RESULTS: UPSW, in which Ca(++) and Mg(++) were replaced with Na(+) , was generated using a water softener with cation-exchange resin. Staphylococcus aureus (Staph. aureus), Staphylococcus intermedius (Staph. intermedius), and Staphylococcus pseudintermedius (Staph. pseudintermedius) were incubated with various fatty acid salts in distilled water (DW) or UPSW and the number of bacteria was counted. Among the fatty acids, oleic acid salt and linoleic acid (LA) salt reduced the number of these bacteria. Also, UPSW enhanced the antibacterial effect of LA on Staph. spp. In spontaneously developed itchy dermatitis in companion dogs, shampoo treatment with liquid soap containing 10% LA in UPSW improved skin conditions. CONCLUSIONS: LA salt showed antibacterial activity against Staph. spp. Treatment with soap containing LA with UPSW reduced clinical conditions in dogs with dermatitis. SIGNIFICANCE AND IMPACT OF THE STUDY: Because colonization of Staph. spp. on the skin exacerbates dermatitis, the use of LA-containing soap in UPSW may reduce unpleasant clinical symptoms of the skin.
