Another problem with the Chow is that he is subject to heat prostration if left in a hot, closed-in area or in the sun. He is particularly bothered by extremely high humidity, especially if the temperature climbs above eighty degrees. Hot-spots, allergies and probably the most common causes. If your Chow starts scratching excessively or has raw, irrated skin that looks infected consult your veterinarian immediately. The Chow needs to be brushed at least twice weekly or more if possible.
Grooming is essential to keep the long, thick coat in peak, clean condition.
Chows have a dense undercoat that supports the coarser outer coat and gives it its fluffy appearance. Many adult Chows have a ruff almost like that of a lion that must be handled with care because it can be stripped away by too much grooming. The puppy undercoat, however should be brushed out when it starts to loosen so that the adult coat may come in properly. Always brush out the dead coat and be careful that the remaining coat does not mat. The rake is useful in the removal of the fluffy undercoat and the pin brush to groom the longer, off-standing guard hairs which are of coarser quality.
