Sirius is a 9 year old Male Aussie mix, weighs 40-45 lbs., current with vaccinations, neutered and we will microchip him. He is heartworm positive and has started on treatment. He is a friendly boy, housetrained, is food possessive, so may need to be the only dog in the home. He has been exposed to children, but they have been a little older, so maybe no smaller children.
