I rescued another Chihuahua.She is 2 years old 4-5 pounds and short apple head(I'll add a picture)She has the most adorable little under bite and smile
She came from a farm with 10 other dogs,10 goats,and a horse and I was told by them ("SHE JUST HAD PUPPIES PULLED OFF HER")two months ago.She has been with us for 3 days now and for the first two acted GREAT was very playful,fell immediately in love with my older Romeo chihuahua and others.Is GREAT in the house no accidents.

PROBLEMS:She threw up twice this morning and is acting not as playful as before..Is Drinking water and ate a few kibbles(not like she has been eating*She eats more normally food wise drinking the same amounts*)(taste of the wild)
She came from a farm with well water!! I DON'T know if it was softened or anything

???? Here on our acreage we have a septic block home CITY WATER. So is this throwing up from her new water change?
I've never had to inter grade a chihuahua to city water from well water.Could this be the reason for her not feeling well and throwing up? What do I do!! find some well water and mix it with my city water or will she be ok in a day if I don't?She is still drinking and ate a small breakfast so far,but with the throwing up obviously not feeling good
