and that is: sometimes it is just their time
my little dog decided one day (about 8 weeks ago) to stop eating and drinking.
well...!
tests at the vet the next day, trying her favorite foods, alternative foods, force feeding her baby food and water out of a little syringe (with no needle of course)...
a couple days later and we did more blood work, urine test, xrays...
she had a strong heart
(oh good, right?)
and she was getting weaker and weaker
one week and $1,000 later, for some unexplained reason, she just died.
omg!
it was as if she decided (for whatever reason) it was "her time" and i prolonged it for about a week by feeding her but she got her way and she died. and i still can't figure it out. and i still can't get over it. and i'm still devastated.
i just googled and found that the lhasa apso life span is 12-14 years. my baby was 13.5 years. but i wanted more. i suppose we always do.
i'm sorry you're going through this. i wish both of you well.
my advice: do what you can and whatever you feel is best.
