Fido’s Flea Shampoo in the 250ml size is a gentle flea shampoo used to help treat fleas, ticks, lice and mites on both cats and dogs. Will not irritate even the most sensitive skin types. Also designed to remove any unpleasant odours, not just mask them, plus has a really lovely fresh, clean fragrance - no chemical smell like other flea shampoos we've tried. Includes natural pyrethrin and biodegradable insectice carbaryl. Leaves the coat softer and shinier. Safe for use in hydrobaths. Throughly wet pet then apply shampoo. Work into a lather. Leave for 5 minutes before rinsing off and drying. Also recommended for treating bedding, especially in summer.
