Free Pet Euthanasia in Fresno?

My dog Kachow is a mix of Chihuahua, Dachshund, and Rottweiler. He is 7 1/4 yrs old and for the past few years hes been having problems walking as well as becoming paralyzed for several days each month. It has been getting worse and worse the past few months. The times he's paralyzed are lasting days longer and he is having a harder time walking after each bout of paralysis.

I have also noticed that he is getting meaner after each episode. He has become aggressive as well. He is constantly growling at my service dog every time she moves. If she's anywhere near him, wthin a foot or two, he's actually bitten her and threatens to bite her daily. I have moved my hand, my leg, or foot near him and several times he's bitten me. Any quick movement within his vicinity and he becomes higly agitated and aggressive.

I am on a very fixed income and am barely able to pay my household bills or buy their food for the month. Because of this I have been unable to take him to the vet for further testing. The one time I did take him the vet told me they need to do x-rays and and an MRI to be able to diagnose him correctly as well as treat him further. They also told me that he will be needing to have surgery for the problem if it's what they suspected it is. I was told that the surgery may not even be able to fix the problem completely and that it may not work at all and could possibly paralyze him.

Since then I have been stressing over what to do. I love my Kachow so very much and this situation has me heartbroken. I have finally come to terms with the fact that my baby needs to be relieved of his pain one way or another. So I have decided to put my baby down. My dilemma is that I cannot afford to pay to have the vet do it for me as he charges too much and will not take payments.

I have spoken to the ASPCA here in Fresno, CA and they will not allow me to stay with him when they give him the shot. I refuse to allow them to take him, place him in a cage until they have the staff and time to get around to euthanizing him. Then they will inject him and just leave him to die. I'm sorry, but I have heard the stories about them not giving enough meds to do the job right and how the animals suffer. I cannot have this happen to my baby.

Is there someone or somewhere that I can take him and stay with him when they give him the injection until he's gone. I'm begging. Please can someone help me? I have found only one vet I might b able to come up with the money for. They charge $50. The only thing is I have no way to get there as the vet is in Selma. I am disabled and don't drive. So far I have been unable to come up with the $50 let alone gas money to get there. If anyone can tell me of a free place to have him euthanized or who will allow payments here in Fresno, CA please let me know ASAP.
