A dog can’t cough up phlegm to avoid catching a cold

1. Owners can measure the dog’s temperature by themselves. The dog’s normal body temperature is between 37.5 degrees and 39.2 degrees to avoid catching a cold.
2. You can feed the dog some probiotics to relieve the symptoms. It is better to put a blanket on it when sleeping at night. Diarrhea is also caused by gastrointestinal flora disorder. If the condition does not improve after 2 to 3 days, If it gets better, it is recommended to go to the hospital as soon as possible for anti-bacterial and anti-inflammatory treatment to feel more at ease.

Avoid respiratory infections when dogs have phlegm and cannot cough it up

Generally, dogs with respiratory tract infections will have inflammatory secretions in the respiratory tract. The accumulation in the trachea is called "phlegm" and accumulation in the lungs It is called "pulmonary effusion" and in severe cases may develop into "pulmonary edema". Even a mild cold and cough is not a trivial matter for dogs. Dogs’ immunity is not as good as that of humans. It does not mean that they will get better on their own after a week.

Don’t ignore it if your dog is coughing up phlegm.

Many times, especially for puppies, the condition gets worse as time goes by. Even if you treat it at home, you cannot control the progression of the disease. I suggest taking your dog to the pet hospital for a checkup before he becomes seriously ill. If the puppy is not fully vaccinated, it will also need to be checked for infectious diseases. Canine distemper is a viral infectious disease with the highest fatality rate in dogs, and its initial symptoms are just cold symptoms.
