Hello Barb, Hogan is doing extremely well. In addition to receiving his final series of puppy shots on Monday, his overall health is excellent! His heart murmur is now completely dissolved, as you predicted that it would! Hogan began puppy obedient training last night, which is always a fun interaction with a variety of puppies! His favorite trick is to fetch the newspaper every morning and carry it to the backyard where we are still working on the handoff:) Thank you once again for raising the best Goldens on planet earth! Cheers! -Scott
