Thank you so much everyone. While the bleeding of my heart is no longer gushing, it is still painful.

I got Taz in September of 1995. My sister brought him home from work and I said "he's mine!". I called him Spazzy Tazzy because he was so full of energy and would tear around the house, up and down the stairs.
Taz has been through so much with me in almost 14 years. We've moved about 7 times together. Each time he would hide out for a couple weeks then be just fine. He was my rock when I was upset. I could be angry or sad and petting him would calm me down. He knew when I was upset and would come to me and sit with me.
He has put up with other animals, dogs and cats, in the places we've lived. The only animal he really bonded with was my mom's Min Pin, Kodi. I think it's because they were both so young together.
Taz is no stranger to the vets office. In the late 90's the vet told me he needed to lose weight. He weighed in at 21 1/2lbs. About 4 years ago he had to have one of his "fangs" removed. And a couple years ago he had a mysterious illness and lost weight. Only it was a little too much weight. He was down to about 12 lbs and that was too skinny for his body. Then in Nov of last year we went through his surgery to remove psuedo-cysts from around both of his kidneys. I believe (as Catty1 said) that may have been the start of his decline. Even though each time he was tested his numbers were "okay". I also believe the two latest additions to the household added more stress on him and that didn't help either.
Last night he weighed in at 6.8 lbs. There wasn't much of him left. So it was time to let him go. Unfortunately, I never saw it in his eyes like many of you said I would. Maybe it was just denial on my part, or he wouldn't let me see it. But the way he acted at the vets told me he was ready. Usually at the vets he will hide his head in the crook of my arm or in my jacket. Last night he laid out and had his head resting on the doctors hand. I said "oh, look how cute he looks". And the doctor said "yes, he is cute. But it's not Taz." I knew she was right. She was ready to send me home with some more fluids to get him through the weekend. But I couldn't do that. I didn't want to walk around the house and see him knowing he would be leaving me. I'd burst into tears every time I looked at him. That would add more stress to him. So I made the difficult decision to let him go right then. Bruce was unable to be with me, but that was okay. I was with him and that's all that matters.

Gosh, I am so sorry I am going on and on like this.

RIP my baby boy, Tazmosis, MoeMoe, Mosephine and several other names that would pop into my head with the moment.
