thanks so much!! He seemed playful and was looking through his bag for cheerios on the way home from the vet. the breeder had him tested for liver shunt and he came up negative, but the test results I got back were for a puppy whose age was 10 months. Either the breeder gave me the wrong copy of the test results OR the vet hospital entered 10 months instead of 10 weeks.
Either way, I just hope he's feeling better soon!
