How Much Does a Good Dog Shampoo Really Cost? (Real Cost Per Bath)
Partager
A €5 shampoo versus a €25 shampoo: which one is really cheaper? The answer depends on a single figure: the cost per bath. And it's rarely the one you'd expect.
How to Calculate the Real Cost Per Bath
To calculate the real cost of a shampoo, you need to divide the price by the number of baths it provides.
A highly concentrated 250 mL bottle (diluted 1:10) can provide 25 baths. A less concentrated 500 mL bottle used undiluted might only provide 10.
Concrete Examples
- Supermarket shampoo, 500 mL for €4 — used undiluted: about 12 baths — €0.33/bath
- "Premium" shampoo, 250 mL for €18 — diluted 1:5: about 25 baths — €0.72/bath
- Gust Care 1 L — diluted 1:5: about 40 baths — around €0.50/bath
Why Dilute Your Shampoo?
Most professional shampoos are designed to be diluted before use. This allows for more even distribution through the coat, better penetration, and easier rinsing. Our 1 L shampoo can be diluted in a squeeze bottle at a 1:5 ratio for around 40 baths on a medium-sized dog.
What Doesn't Get Calculated but Still Matters
A cheap shampoo that irritates your dog's skin means a €60 vet consultation plus a €25 dermatological cream. That's the real cost of a bad shampoo.
