Tasha Alternate Ending

I opened the white creaky door expecting the usual, being attacked with kisses by a little red haired pomeranian (AKA the ankle biter.) I got inside, but nothing. Tasha wasn’t by the door. Everything was silent. Maybe she’s getting her hair cut.
I walked to the end of the hallway where we kept her faded, red dog bed that was always heaped with blankets. There I found her lying in the bed. She looked up at me with the saddest puppy eyes I've ever seen. Her breathing was heavy, she trembled as she just laid there perfectly still. I called my mother, and all I said was “it’s time.”
She knew exactly what I meant by those three words.
She replied back, “okay, on my way.” She left work early to come pick us up.
I picked Tasha up and just held
I grabbed Tasha, and we headed out the front door. There we sat on the cold cement steps waiting for my mother to arrive. I heard the sound of the brakes squeak as she pulled to a stop in front of the house. The car ride to the clinic was all a blur. All I can remember is the way Tasha’s little body shook in my lap.
We arrived at the clinic. I had never walked so slowly towards a building in my life. My heart felt like it was in my stomach. I was carrying her, and she felt almost weightless. Her body had slowly been deteriorating since we found out she had congestive heart failure. Once she got sick, she stopped eating, playing, and became very distant from my family and me.
As we walked in, she had one of her wheezing attacks. When this would happen, her whole body would contract in and out, and this horrible screech would come out of her, lasting anywhere from seconds to minutes. Everytime this happened it was very obvious that she was in pain. I would just sit by her on the floor and comfort her the best I could. This reassured me that I was making the right decision to put her
I laid Tasha down on the cold metal table. All she could do was look at me, and I could hardly look at her. I just stared at my reflection on the cold table where my beloved dog would take her very last breath.
“I don’t mean to rush you guys,” the vet said quietly as he entered the room “but are you ready?”
How could I possibly be ready to kill my dog? I nodded yes because the words couldn’t come out of my mouth.
He left the room and came back with a needle.
I just stared at it, thinking that this thing will be putting my dog to sleep for the rest of time. I looked at Tasha and thought, this is it.
I leaned against the cold table to hug her one more time. I gently placed my head on her chest while my arms were wrapped around her frail body, and I heard her heartbeat for the very last time. I whispered to her, “don’t worry Tash. You will no longer be in pain. It’ll all be over soon.”
At the moment my eyes started to fill up with tears.
He approached the table and said, “I am going to insert the needle now.”
I stood up and wrapped my arms around my mom and turned my head the other way. I just had to look away.
I heard Tasha let out a little whimper, and my heart fell to my stomach all over
