The 2 in 1 brush is very useful because it is very easy to use. One side is bristled for short or medium hair dogs and helps to remove loose hair and dirt and the other side with long bristles is like a carder and can be used for long hair dogs, to remove knots and dead hair. To begin, we must make a parting on the hair and separate it. With one hand grab the top hair and with the other, brush, stretching the hair from the roots to the ends. WARNING: do not touch the dog's skin as this could cause irritation. The way to proceed with the combing is from the bottom to the top. That is to say, giving the opposite direction to the direction of hair growth. This is favorable for our pets, as it remains free of knots and well stretched. Characteristics: - For long and short-haired dogs - Plastic handle - Detangles knots - Removes dirt, dust and hair Sizes : S- Length 19,5 x width 6 cm L- Length 24,5 x width 6,5 cm
