<human>: My families dog(dachshund) has been diagnosed with diabetes, and my parents have decided on euthenasia.. I've offered to pay the vet bills(very expensive) and the insulin etc. However their not willing to give the needles twice a day. To be fair my father works out of town as well so its my mother. My younger sister who still lives at home said she would do the needles whenever she can(most days). However they won't budge, and have basically shown resentment towards me for trying to help.

I love the dog very much, and I do not know what to do.. My hands are tied, and I'm trying everything I can.

I hope they change their mind, the dog is only 8.5 and otherwise very healthy..

It just seems ludicrous in my mind to put down a dog simply because it has diabetes.. Ultimately there's only so much I can do, but I'm conflicted and heartbroken.. So I needed to vent.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: my 8.5 yo dachshund has diabetes, and my parents plan on putting her down, because they feel the needles are too expensive, and too much of a hassle.
