About a month ago, I was having a terrible day at school. Just one of those days and after I got out, I drove straight home. When I got home, I remembered my housecleaner had come today so I went through the front door as to not let the dog out. When I walked in the front door, I heard the carbon monoxide meter going off, and remembering how it freaks my dog out when she hears it, I go upstairs and turn it off. I started to notice something was wrong when I walked in the door but didnt think anything of it. When I walked downstairs and opened the door to the garage, my dog wasnt there. Remembering that she sometimes sunbathed out on the patio, I walk into the backyard from the garage and start calling her name. Nothing happened so I ventured farther into my backyard. Finally I turn the corner that leads to my pool and see her laying there. At this time I start patting my legs calling for her to come over to me only to notice she is not responding. I walk over to her and find that her toungue is black and she is stiff as a rock. To my worst fears she was dead and had been dead for a while. Before then, she was perfectly healthy and happy. It appeared that she had died while barking at the pool due to a heart attack. I still remember the vivid details that happened that day when I found my 4 year old dog dead in the backyard. It was one of the worst days of my life.
TL:DR Walked into my backyard to find my 4 year old dog dead.
