It is normal for urine to be yellow and sticky after taking some medicine during a cold. You can't just give it Radix Isatidis, but also add some anti-inflammatory drugs. Infants can be given anti-inflammatory drugs, a small amount at a time, twice a day. Be sure to keep your dog warm at night. When the weather is sunny during the day, we should also pay attention to let the dog bask in the sun, pay more attention to feeding clear water, control the temperature of cold water during the day, and add a little hot water.
