Meet Logan. He is one of 3 we got from the 50 Shelties Atlanta Humane Society. He is 6 to 7 years old, oversized at about 17.5 inches and thin at 28 pounds. Unfortunately he is heart worm positive. He has had blood work and chest x-rays and has started on Doxycycline. He will be in rescue for several months being treated for the heart worms. He is a little timid but very sweet!
