Girl's Best Friend?

So, I have been thinking A LOT lately about getting a puppy of my own. I'm pretty "fun-sized" 5'2'' a little under 110lbs so I've always wanted BIG things. For example, I've always wanted a big SUV or truck (even though I drive a small scion tC)...and I've also always said I want to get a HUGE puppy when I get one!

I am in love with Mastiffs! So I have been reading up on Mastiffs, and all of the hybrid "designer" breeds of Mastiffs there are. Out of 17 different hybrid Mastiffs, I narrowed it down to 11 (haha) and now to about 4, but I still can't decide.

Top of my list is the "Daniff or Great Daniff" a cross between a Great Dane and a Mastiff:

Apparently from something I read online that someone wrote, they have a 4 month old Daniff and it's already way over 60lbs.

Next choice is the "Mastador" a cross between a Labrador Retriever and a Mastiff:

This Mastador is only 15 months old and weighs a little over 100lbs! So cute!!

Now this hybrid Mastiff, the "Irish Mastiff" a cross between a Mastiff and an Irish Wolfhound:

Okay, so this dog is just absolutely stinkin adorable! Reminds me of an old man and I love the look of it! According to the website this picture came from, this Irish Mastiff is 6 months old! It's so big too :)

The last hybrid I narrowed my long list down to is the "Giant Maso Mastiff" a cross between an Old English Mastiff and a Cane Corso Italiano. My best friend's family has a Giant Maso named Willow and when I met her I fell in love with the dog! So I am leaning towards the Giant Maso.

This is a Giant Maso Mastiff at 4 months old and below, the same dog, fully grown at 140lbs.

I am looking for breeders currently or anyone who knows about these types of hybrids. Any input would help :) xo G
