I purchased 2 sibling chihuahuas from Kirk and Tracy Newton at Tinytowntexas in 2007. The male died at age 2 in 2009, from pulmonary stenosis and the female died at age 3 in 2010, from pulomary edema. This man is not a reputable breeder; he runs a PUPPY MILL in Edgewood, Texas, near Dallas. I sent him the necropsy of the male and he never responded. He is still using the VERY same breeders that my pups came from. How can someone like this sleep at night. PLEASE BEWARE OF THIS MAN.
