Rocket seems better but is still not quite himself. He seems more tired than usual, but has also been going on at least 2 walks a day since the weather got better. Maybe we're just not seeing that pent up energy that he had when he was stuck in the house due to snow and ice.
We have a vet appointment to update his shots this evening, so we'll have him checked out and take along a couple of "samples". Hopefully it's nothing, but will let you know what we find out.
