massive mastiffs
much ado about the big dog
Massive Mastiffs was launched in 2017
as an online shop dedicated to selling big dog products and accessories.
The store was started when the original owner discovered that most pet stores, whether brick & mortar or online, did not have nor stocked dog products that specifically cater to the Big Dog. Knowing that other Big Dog owners like himself were ignored, it made sense to make a way to accommodate the needs of the Big Dog that their humans appreciate.
In the same consideration as "Big & Tall" stores' have impacted the menswear market, there has been a great desire to have a special place for the Big Dog, and the humans that love them.
That place is called Massive Mastiffs - The Big Dog Store.
