Yes my chihuahua actually turned out to be a very healthy dog with NO problems whatsoever....and to think we got her 14 years ago in...GREECE! Here they're not very responsible for animals and not so caring....I mean, there are people that care but a lot more that don't!
So we got her from a pet shop, we didn't know anything back then...we just wanted a white chihuahua (a breed not even known in Greece back then, it was the pre-Paris Hilton era, LOL ) and a friend found one in a pet shop.
She never had any problems and she's just the best dog ever....she even travelled to the US at 13 years old when I stayed there with my mom for 8 months cause I was really sick and needed to get treatment....she's just been great.
Her vet says she's lucky to still be alive at this age....and because she's overweight, she's around 15 pounds...a chihuahua!!! But he says she's too old for a diet now....and she loves food!
