Causes of Bichon Frize body odor:

1. Bichon Frize body odor may be caused by not bathing for too long, especially if the dog has sweat glands on its foot pads, which has not been bathed for a long time. It smells bad when you clean it.

2. Bichon Frize body odor may be an oral disease. When a dog suffers from stomatitis or tartar on its teeth, it will cause bad breath and then body odor.

3. Bichon Frize body odor may be a skin disease. When a dog suffers from diseases such as fungi, mites, eczema, or is infected with parasites, it may cause the dog's skin to smell bad.

4. Bichon Frize body odor may be an ear disease. If a dog suffers from ear mites or bacterial infection, it will cause the ears to emit an unpleasant odor.
