Petsup straight and smooth dog shampoo review

At around ₱199 as of August 12, 2026 for a dog shampoo sold on a smoother coat. What it is doing is worth being clear about.

A smoothing shampoo coats, it does not change

Hair shape is structural. A curly coat is curly because of how the follicle grows it, and nothing in a bottle changes that.

What a smoothing formula does is deposit a conditioning film along the hair shaft. That flattens the cuticle so the hair lies down rather than standing away, reduces friction so strands slide past each other instead of knotting, and makes the surface reflect light more evenly, which reads as shine.

The practical result is a coat that is easier to brush and looks tidier. That is a genuine benefit, especially on a long-coated dog in a humid climate where frizz and tangling are constant.

It is not straightening, and the effect washes out.

Brushing does the same job, free

Worth saying because it is the better habit.

A brush pulls dead hair out before it can mat, and it spreads the dog’s own oils from the skin along the length of the coat, which is exactly the effect the conditioner is imitating. A few minutes every couple of days does more for a coat than any shampoo, and it doubles as a check for ticks, lumps and sore spots.

Mats are the reason this matters. Once a coat mats properly it pulls on the skin, traps moisture underneath, and has to be cut out rather than washed out.

How often to bathe

Every four to six weeks for most dogs, unless a vet has asked for a medicated schedule.

More than that strips the oils the skin depends on, and dry skin itches, which produces the scratching an owner then tries to wash away. In Philippine humidity dogs do get smelly faster, and the answer between baths is brushing, a damp wipe, or a waterless product.

A dog that smells again within a day of a bath has a skin or ear problem rather than a dirt problem.

What the brand’s own store adds

Petsup sells this itself rather than through a reseller, which in a category where almost nothing publishes an ingredient list is one of the few quality signals available: a single party accountable for the formulation.

The brand’s plain dog shampoo 500ml is the same price with far more Shopee ratings behind it, so if the smoothing angle is not what you need, that is the better-established bottle.

Who this shampoo suits

Buy this if you have a long or tangle-prone coat, you brush regularly, and you want a wash that makes the brushing easier.

Skip it if you expect it to change the coat, or if the dog’s problem is itching rather than tangling.

The alternatives on this shelf

For the brand’s most-bought dog bottle at the same price, see the Petsup dog shampoo 500ml. Between baths, the Petsup dry shampoo odor control costs half as much.
