Where to Buy the Dexas MudBuster — PetSmart vs Amazon (2026)

Why people search for the MudBuster at PetSmart

Most paw cleaner buyers want to see the product in person before they commit — the MudBuster is a plastic cup with silicone bristles, and feeling the bristle firmness in hand answers the "will my dog tolerate this" question faster than reading reviews. PetSmart is the natural first stop because it's the biggest pet retail chain in the US, and the Dexas brand has shown up in their stores on and off for years.

The catch: the MudBuster has never been a permanent PetSmart SKU. Stock comes in waves, often regionally, and a store that had it in stock six months ago may not have it now. The petsmart.com search box returns the MudBuster in some periods and not in others. That's why "Dexas MudBuster PetSmart expansion 2025 or 2026" shows up as a common search query — people want to know whether the product has been added permanently.

Current availability (May 2026)

If you walk into a PetSmart hoping to find the MudBuster, the Medium is the size most likely to be on the shelf — and the size most people need. The XSmall and XL are almost never in physical stores; for those, Amazon or dexas.com is the only reliable source.

The case for buying online instead

Three reasons most owners end up on Amazon even when there's a PetSmart nearby:

1. Size selection. The "right" MudBuster size depends on paw width, not body weight. A Beagle and a Corgi can have different paw widths despite similar weights. If the store stocks only the Medium, the Beagle owner who actually needs a Small has to either buy the wrong size or come back another time. Amazon's listing shows all five sizes side by side with the official sizing chart.

2. Color choice. The standard run includes Pro Blue, Fuchsia, Grey, and Light Gray. PetSmart usually stocks whichever color the buyer ordered, often just one option. Dexas also runs seasonal colors (limited-edition pinks, greens) that show up on Amazon and dexas.com but rarely in physical stores.

3. Returns and reviews. The MudBuster has 18,742+ Amazon reviews as of 2026, with size-specific feedback in many of them. If a Maltese owner has already documented that the XSmall is too tight, that's information PetSmart's shelf doesn't give you.

What about the Dexas MudBuster "expansion" rumors?

Some search variants of "Dexas MudBuster PetSmart expansion 2025" or "2026" come from speculation about whether Dexas has signed a permanent retail agreement with PetSmart. As of May 2026, there's no public announcement of an exclusive or permanent partnership. The MudBuster's primary channel remains Amazon, with PetSmart and Chewy as secondary distributors that stock the product opportunistically.

If you see the MudBuster on petsmart.com and want to confirm it's the genuine Dexas product (not a look-alike), check that the listing references US Patent D799,126 — that's the original Dexas patent. Knock-offs do exist; they use thinner plastic and stiffer bristles that some dogs refuse outright.

Buying decision in 30 seconds

If you can walk into a PetSmart in the next day or two and a Medium is in stock: fine, buy it there. Same product, same price. For everything else — any other size, a specific color, sizing uncertainty, or a dog with a sensitive feel that benefits from reading owner reports first — buy on Amazon. The 18,742 reviews and the all-five-sizes selection are worth more than the savings of one day of Prime shipping.
