How to use dog size in grooming prices without oversimplifying the job

Size bands are a starting point, not the pricing engine

Small, medium, large and giant categories can make a price list easier to understand, but size alone does not predict the workload. A small double-coated dog with compacted undercoat can consume more time than a larger short-coated dog. A nervous dog may need slower handling. A heavily matted coat may change the service entirely.

The most reliable approach is to use size as a planning input, then price from the expected minutes and direct cost of the actual appointment.

What size changes in a grooming business

Larger dogs often increase bath and drying time, shampoo usage, table time and physical handling. They may also use more conditioner, towels and dryer capacity. Those are genuine cost effects. The mistake is assuming every larger dog automatically needs the same percentage uplift.

If the business uses published size bands, define them clearly. Weight can be one guide, but body shape and coat volume can make weight alone misleading. Internal notes on breed, coat and historic appointment time are often more useful than the label itself.

Coat type can outweigh size

Short smooth coats, long silky coats, dense double coats, curly or wool coats and hand-stripped coats have different time and equipment demands. A grooming business should therefore avoid a single size matrix that assumes identical labour within each band.

Use the expected service time as the core driver, then add any predictable product, blade, scissor or specialist-tool cost. Where coat condition is poor, assess the dog before confirming the final service and price.

Separate base service from extra labour

A useful pricing structure is to define the expected base appointment for the service, then account for genuine extra time. Examples include de-matting, de-shedding, behaviour-related breaks, hand stripping or additional finishing work. That keeps the price explainable and helps staff understand why two dogs of the same size can legitimately cost different amounts.

Build size-based prices from appointment economics

1. Estimate the base service minutes for the size and service.
2. Add coat, condition and handling time.
3. Multiply total paid minutes by the loaded labour rate.
4. Add shampoo, conditioner, specialist products, utilities and equipment wear.
5. Allocate salon overhead or mobile travel costs.
6. Allow for payment fees and other predictable leakage.
7. Apply the retained margin target and minimum charge.
8. Use the resulting prices to build understandable customer-facing size bands.

Why a minimum grooming charge still matters

Short services such as nail trims or quick tidy-ups can use booking capacity, customer handover time, cleaning time and payment processing even when the hands-on service is brief. A minimum charge protects the business from filling the diary with low-value appointments that do not recover overhead.

Use real appointment history to refine the bands

Once the business has enough completed appointments, compare planned time with actual time by service, size and coat profile. If “large full groom” appointments consistently take longer than the model assumes, update the underlying time rather than applying random surcharges at the till. This creates a more defensible and trainable pricing system.

Common size-pricing mistakes

• treating weight as a complete measure of workload
• using breed labels without checking coat condition
• failing to charge for significant additional handling time
• pricing extra product use but ignoring extra labour
• using market prices without checking the salon's overhead
• making every adjustment a vague “large dog surcharge” instead of linking it to the work
