For about the past 3 weeks, may be a bit longer, every time I've been in the garage I got that wiff of something dead, yesterday I could also smell it outside the garage. Now my garage is more of a junk store than anything else so I've been putting it off, thinking dead rat or neighbours cat that went missing in August. Ok just decided to investigate and it wasn't good. I have a freezer in the garage that has a few roe skins and feet for dog training. About 7 or 8 pheasant carcasses which I breasted out last season and saved the rest as fox bait along with some other bits of roe carcasses. Well something had fallen off a shelf and by a stroke of bad luck had flicked the plug socket switch off. When I opened the door the contents were past defrosted, they were decomposing and giving off some heat. There was about 1/2" of blood in the bottom. I started to bin everything and then went to fetch a bucket of water to start cleaning it out only returning to find the bloody dog in there with a roe skin both dripping in rancid blood. I'm so glad I made it to the back door before the dog or things would have not been good.
All clean now but that smell is lingering DOH!
