Oh, Poor Anvik~ He sure has been through the Mill today!!!! I feel so bad for him, but I'm glad that his lungs are working !!!!! ;)
I'm very optimistic since reading your up date, ( blood work is normal :o )
He'll just have to take it easy for a few weeks, and you'll have to keep an eye on him!!!
Thank-You for posting the up date, and Please give Anvik a Hug!!!!!
