BluePet Undercoat brush review

An undercoat brush that clears loose hair and works at light matting, sold as a combined thinning, trimming and combing tool for long coats.

What we take from it The cheap workhorse of this family. It does most of what a FURminator does on a long coat, more gently and more slowly.

What it is

An undercoat brush for long-coated dogs and cats: it pulls loose undercoat out while leaving the topcoat, and BluePet presents it as thinning and trimming as well as combing.

Gentler than a blade

The teeth part the coat and pull loose hair between them rather than cutting across it. On a coat that is starting to knot, that is a real advantage — a rigid deshedding edge meets the knot and drags, while a rake works through it. The trade is speed: this takes longer over the same dog.

Where the thinning claim needs care

A tool that thins is a tool that removes living coat if you keep going. Weekly sessions on a heavy undercoat are what it is for; the same patch every evening produces a thinner coat rather than a cleaner one.

Where it stops

Felted mats against the skin. Every brush on this page stops there, and the next step is scissors in the hands of someone who can see what is underneath.

Availability

No such listing: the American Amazon shop answers the reference with a search box rather than a page.

The questions owners ask

Undercoat rake or deshedding tool?

A rake pulls loose undercoat out between teeth; a deshedding edge cuts and lifts it. The rake is gentler and slower, and it copes better with a coat that is starting to knot. For a coat in good condition and full moult, the deshedding tool clears more per pass.

Does it really trim?

BluePet describes it as thinning and trimming as well as combing, which means the teeth part the coat. Used weekly that is useful on a heavy coat; used daily on the same patch it takes out more than the moult, and the coat looks thinner rather than tidier.

Can it deal with mats?

Light tangles, yes — with patience and short strokes from the tips inward. A mat felted against the skin, no. That is a job for scissors in the hands of someone who can see the skin, which usually means a groomer.
