our dogs are very good about staying out of the garage, unless someone is in the garage , and theyre called in, they dont go into the garage. from working on the K20 i have a catch pan of misc fluids sitting on the floor, under the frame for my 92. mind you neither dog will go under anything. so, i hadnt put too much thought into it because of them not ever going into the garage, and neither liking to go under anything. i was out working on the truck for about 45 mins earlier tonight, probably 25' from the door, and the door was open. i never saw her go in, nor did we see anything unusual about her. about an hour ago, our female came flying out of the bedroom, we heard her hit the wall in the hallway at least twice. she then bolted around the corner, hit the rug on the ceramic tile at the entry way, and barrel rolled head first into the door. she got up, and tried to come to both me and my dad. she couldnt make it across the living room, she kept falling over, and she couldnt sit up straight. after a while we got her calmed down, and she went right back to normal. i'm 99% positive that she didnt go into the garage and get into the antifreeze, but that 1% is scaring the hell out of me. what other symptoms would i be noticing at this point (roughly 6 hours after the fact)? anything we should watch for? im probably not going to sleep much tonight. lesson learned, the antifreeze will be in jugs tomorrow.
