Grooming and coat
Should I brush my dog before or after a bath?
Last updated 23 September 2026 · How we write and check this
Short answer
Always brush before a bath, not just after. A full brush out beforehand removes loose hair and mats that would otherwise trap water and shampoo, and a mat left in place before bathing usually tightens once wet, turning a five minute fix into a much longer one after the coat has dried.
What skipping the pre bath brush costs
Shampoo and water trapped inside a mat can leave the skin underneath damp for hours after the rest of the coat has dried, which is one of the more common overlooked causes of a musty smell or skin irritation in dogs with dense or curly coats that are bathed without a proper brush first.
A quick pre bath routine
A five to ten minute pass with a slicker brush and a comb check, focused on the usual trouble spots behind the ears, under the legs, and around the collar, catches most tangles before they meet water, and takes far less time than untangling the same knots once they have tightened.
Brushing still matters afterward
A second brush while the coat dries, working in sections, finishes the job by keeping hair separated as it dries and giving a smoother, shinier result than skipping straight from towel to done. Both stages serve different purposes and neither fully replaces the other.
Key takeaways
- Brushing before a bath prevents mats from tightening once the coat is wet.
- Trapped water inside an unbrushed mat can leave skin damp for hours after a bath.
- A second brush while the coat dries keeps hair separated for a smoother finish.
