Hi Quanzhan, yes I remember you and Zack. He went through so much with heartworm, but thankfully he did recover and it sounds like he is doing wonderful now. He must love the life he is living , playing with his doggie friends, swimming and chasing birds, etc. etc. Thank you for updating us on Zack and lots of hugs go to him. I'm sure Logan would love to hear about him, but she is in Las Vegas right now on business and pleasure.
