She is old now....3.5 years to be exact. She has lost use of both her front and back legs now and can no longer chew. She sorta just flops around and tries to move where she can but fails. I have to feed her baby food throughout the day and give her water through a dropper. My question is, what could be causing this? Should I put her down or let her go here at home? She was doing bad before and improved tremendously when I took her with me on vacation....now that we are back home her condition continues to get worse. The vet I take her to says euthenasia done by her is with an injection to the heart. That seems horrible :/ any feedback is appreciated.
