Today i was out mowing an account thats beside this really run down apartment in town. They have a huge rottwiler mix on a chain in the yard and it ignored me till I stepped off my Proslide and checked under a few trees. When it saw me walking it started barking like crazy and charged me showing its teeth.. I wasnt too worried till it reached the end of its chain and snapped its collar in half There was about 20 feet between me and the dogs chain and i swear I almost lost that pair of tighty whities. The good news is when it reached me he did some sniffing then was friendly as anything. Does anyone carry mace spray with them or anything for dogs?
