In general, pit bulls aren’t aggressive with people but are “less tolerant” of other dogs than many other breeds, says Pamela Reid, PhD, vice president of the ASPCA’s Animal Behavior Center in New York. They also have “great tenacity. They put their mind to something, and they do it. That’s what makes them great dogs for sports like weight pulling. They are very strong, athletic animals," Reid says.

Glaucoma: This is a painful disease in which pressure in the eye becomes abnormally high. Eyes are constantly producing and draining a fluid called aqueous humor — if the fluid doesn't drain correctly, the pressure inside the eye increases causing damage to the optic nerve and resulting in vision loss and blindness. There are two types. Primary glaucoma, which is hereditary, and secondary glaucoma which is a result of inflammation, a tumor, or injury. Glaucoma generally affects one eye first, which will be red, teary, squinty, and appear painful. A dilated pupil won't react to light, and the front of the eye will have a whitish, almost blue cloudiness. Vision loss and eventually blindness will result, sometimes even with treatment (surgery or medication, depending on the case).
Two-color varieties always have a white base color with areas of the second color. Tan and white is the most common two-color variety, but there is a wide range of other colors including lemon, a very light tan; red, a reddish, almost orange, brown; and liver, a darker brown, and black. Liver is not common and is not permitted in some standards; it tends to occur with yellow eyes. Ticked or mottled varieties may be either white or black with different colored flecks (ticking), such as the blue-mottled or bluetick beagle, which has spots that appear to be a midnight-blue color, similar to the coloring of the Bluetick Coonhound. Some tricolor beagles also have ticking of various colors in their white areas.[33][34]
