CHOOSING A SUPPLEMENT
Feed the coat and the skin beneath it
Pet Gala brings collagen, omega fats and ceramides together for daily skin-and-coat nutrition. It is a prepared powder for the usual meal, so caring for the fur also includes the skin beneath it.

LA PETITE LABS
Pet Gala — Skin & Coat Defense Complex
Collagen is a protein ingredient; the omega blends and ceramides add a different part of the formula. Ceramides naturally help form the outer skin’s barrier against water loss. Pet Gala combines these with hyaluronic acid, biotin, zinc and other companion ingredients in its 15-active Skin & Coat Defense Complex.
Choose Pet Gala for that combined nutritional approach. It has not been shown to regrow bald patches, and persistent or patchy hair loss still needs its cause assessed. The full recipe includes marine, whey, beef and chicken ingredients, so check it against any food restrictions.
From $1.43/day
