We put our Cochy to sleep today...

Question:
 I am an absolute mess right now... I can't stop crying. Today we just euthanized my 17 year old Cocker Spaniel, Cochy. She was such a beautiful and wonderful dog with an amazing personality. I hate this feeling... I feel so guilty. She had been on a special diet for her kidneys for over a year... This past year she slowed down a lot. She was always extremely strong and healthy before this past year. She hadn't eaten for the past 3 days and over the course of the past few months had lost a lot of weight. She still acted happy though... responsive and sweet. We took her to the vet this morning and he told us that her kidney enzymes were sky high and her liver wasn't doing well either. She only would have a few days left... or we could spend $1000 getting her better, but she'd only last a week or two more. I made the decision to euthanize her today at 4 PM. I spent the next 5 hours with her... petting her and giving her good food. She was so responsive to me that it broke my heart knowing that I had to put her to sleep. I feel so guilty... she still wagged her tail and licked my hand. Was it wrong of me to do what I did? I didn't want her to pass away painfully. The vets were actually shocked at how resilient she was. They said with enzyme levels that high, she should be feeling awful. My baby girl was strong though. She also had severe arthritis, which made her walk really slow. Additionally, her cataracts were quickly robbing her sight... and she was experiencing hear loss. When I list all these things, it sounds like she was awfully sick. Perhaps she was... but her personality just shown through it all, which makes me feel so bad for doing what we did. All I do is cry... one minute I'll feel ok... and then a wave of intense crying and turmoil comes over me. I miss her... I will never forget taking her in the car and going to the vet's office. What a horrible day... my baby is gone.
Answer:
 So sorry to hear about Cheeko... it's so hard losing a pet. I think that's the worst part about having them, but they're worth it, right? I just am going through an emotional roller coaster... I'll be ok for a bit, and then burst into tears the next. It's the worst feeling in the world... But it's nice to know that I'm not the only one dealing with this kind of pain.
Answer:
 :'( Hi ~ I'm sorry about your loss of Cochy, I hope you can find peace inside knowing how she lived her life, loving your love. The painful decision you had to make, came from that same love and undoubtedly was the kindest thing you could have possibly done for her. I lost my dog, a Griffon called Ganny, 4 mths ago and here I sit today, still crying, still missing him as if it were yesterday. It was very sudden, totally unexpected and he died at home in my arms, total nightmare. He was my baby, everything revolved around him. My rollercoaster ride is still going, it's just a little slower and I've become accustomed to the pace. I don't know how I'd have made the decision, had I known he was suffering, but I know I couldn't have prolonged any misery :-( I'm sure if our dogs could speak, they'd forever be saying thankyou. I wish you well throughout this tragic event in your life, keep talking to her, vent your feelings, she will live on inside you and guide from within, knowing now is the time when you need her the most. Ganny does for me, he just needs the occasional nudge... Gans mum, also still at a complete loss sometimes.
