Why a medicated bath?
Many skin diseases and infections improve, sometimes resolve, with medicated baths. They are used as prescribed, and often work better alongside an oral treatment or a cream on the skin. The bath itself is simple and very doable at home.
Skin to treat
An infection or skin disease your veterinarian confirmed after an exam.
Alongside other care
Often more effective with a tablet or a cream at the same time.
The contact time
The whole effect comes from leaving the shampoo on for a few minutes; the watch is your ally.
A medicated bath often goes alongside a cream or ointment on the skin. See the creams and ointments guide
What you need
Nothing complicated: mostly lukewarm water, a way to keep time, and the prescribed shampoo.
Bathtub and sprayer
Ideally a handheld shower head. In warm weather, outdoors in a well-drained area. Otherwise, a bowl or small bucket to pour water.
Lubricating eye ointment
Sterile, to protect the eyes from the shampoo.
A watch or timer
To respect the contact time, which is essential.
Medicated shampoo
The one your veterinarian prescribed.
A rack for the tub
For cats, so they can grip the bottom.
Two people is safer
For a large dog or a pet that dislikes baths, plan for two people: one to lift or steady it safely, the other to wash.
Before you start
A medicated shampoo only suits certain specific conditions: use it only if your veterinarian recommended it after examining the skin. Contact us promptly if you notice:
- An increase in skin discharge.
- More redness, swelling, or heat over the area.
- Pain that is increasing.
- A condition that is spreading.
- Being unable to give the bath (an uncooperative pet, pain, or doubt about doing it properly).
Tell us about other conditions
If your pet has a heart, respiratory, or eye problem, let us know: a poorly tolerated bath can worsen them, and bathing may then be inadvisable.
Is your pet strongly resisting? Stop.
If your pet struggles enough to make the bath difficult, stop and call us. Do not put yourself at risk. Strong reluctance can also hide another skin problem that deserves a prompt check.
The bath, step by step
Two things make all the difference: the contact time and a long rinse. The rest is simple.
Protect the eyes
Place a thin strip of sterile lubricating eye ointment in each eye (about ¼ to ½ inch, or 0.5 to 1 cm). This keeps the shampoo from irritating the eyes, since pets do not keep them closed.
Settle in and wet the coat
Place your pet in the tub and soak the coat with lukewarm water, pleasant to the touch. If the skin is red or inflamed, water that is too hot or too cold can be very painful.
Wet from head to tail
Start at the top of the head, then work down the spine to the base of the tail: gravity helps the water reach the skin. One hand directs the stream (or pours the water), the other works the water through the coat. For a fine coat, under a minute is enough; for a thick coat with dandruff, secretions, or debris, allow up to 10 to 15 minutes to soften and loosen the buildup.
Shampoo and contact time
Lather the shampoo over the whole body. Most medicated shampoos need to sit for 10 minutes (or the prescribed time). Time it: this contact time is what makes the bath work.
Rinse meticulously
Rinse thoroughly until no soap remains. A good rinse lasts at least as long as the shampoo, often 10 minutes or more: soap residue irritates the skin too.
Towel dry
Dry with a towel only, never a hair dryer after a medicated bath (we explain why in the FAQ).
A tip for cats
Place a rack at the bottom of the tub so the cat can grip it. Tilted at 45 degrees, it keeps the cat from sliding on the stainless steel and noticeably eases its anxiety.

After the bath
Once the bath is done, it remains to watch the skin over the following days.
- A passing redness: the skin can look redder right after the bath, because circulation increases. This is often normal.
- Compare each day: at the same time, look at the color, warmth, and comfort of the skin. Gradual improvement is reassuring; worsening warrants a call.

The secret: contact time and rinsing
Protected eyes, lukewarm water, the shampoo left on for the prescribed time, then a long, careful rinse and a towel dry: that is what makes a medicated bath work. Follow the prescribed schedule, watch the skin day by day, and call us at the slightest doubt.
