Why Smell Persists and How Shampoo Helps
Dog odor originates from skin bacteria, sweat glands, or environmental factors. A good shampoo tackles these root causes.
Common Causes of Dog Smell
• Skin infections or allergies can release strong scents.
• Ear infections often produce a foul odor.
• Dirty paws and fur traps mud and waste.
How Shampoo Eliminates Odor
Shampoos contain surfactants that lift dirt, antibacterial agents that reduce bacteria, and fragrance or natural oils that mask smells.
Choosing a pH‑Balanced Formula
Dogs have skin pH around 6.0–7.0. Shampoos with a matching pH preserve natural oils and avoid irritation.

Tea Tree Oil and Lavender
