Compound Cortex Phellodendri liquid coating is a traditional Chinese medicine, and its main component is Cortex Phellodendri. Cortex Phellodendri has antibacterial, anti-inflammatory, hemostatic, and dampness-removing effects, and is often used to treat oral ulcers and skin inflammation. However, for dogs, it is not appropriate to use compound phellodendron bark liquid coating. The reasons are as follows:

1. Different animals have different physiological structures and metabolic abilities, and their responses to drugs are also different. Therefore, drugs for human use cannot be directly applied to dogs.

2. The dog's skin and mucous membrane are highly sensitive to chemicals, and the components in the compound Cortex Phellodendri liquid coating may cause irritation or allergy to the dog's skin.
