hi, i am a new member. i also had 2 chihuahuas ,
one is cream , and one is tan with black mask.
Blue color chihuahua can be eye-catching. but the blue or gray color is the result of the pairing of two recessive genes for dilution that cause hair that would normally be black to be gray instead. for some reason, these blue/gray hair are often associated with skin problems. but not all blue chihuahuas are affected . those lighter shades of gray/blue are more likely to be affected. no cure are avalible. soo blue chihuahuas need more care than others, a healthy diet with help.
