You want a proper Dominican Dog
Aparently the original dogs were like their own "breed" until it got mixed with muts and strays. I think I have one which unfortunately has been neutered. I would suggest that a trip to the campo might still reveal one or two. - You've seen them around, stocky, light coloured, big erect ears, teeth like "Alien". - These I'm told are the true original dog but perhaps I'm mistaken, are there any experts who can say one way or another?
Every single Dominican who comes to my door is terrified of my dog - she's not big by any standard but they know they're gonna get bitten and 90% of the time I end up apologising for the sudden rip in the seat of their pants!
She spends her days winding up next doors Rottie's - what a dog!
