Tachi needs help!

Tachi is my 7 year old Yorkie, she has recently gotten soo sick.  She has a distended belly and is in a lot of pain. Right now I am recently taking care of a very sick mom and a daughter who is not well either.. I love my dog but I am unable to financially get my dog the care she needs and I do not qualify for the programs for assistance. Meanwhile Tachi is in major pain she is unable to eat or move around without pain...Please help Tachi if you find it your heart  it would be greatly appreciated
