What to do if your dog has poor heart and lung function

Firstly contact with other dogs needs to be avoided as frequent asthma can easily be triggered if they fight or shout. Secondly dogs should not be strenuously exercised or overworked, and in summer must be kept out of the heat and sun and in a cool, ventilated place is best. If the symptoms are critical, take them to hospital as soon as possible. You also need to pay more attention to the diet in general, try to eat dog food and not feed people food high in salt.
