I think we can rule out Fanconi and any kind of actual injury to the paw based symptoms and timing of episodes. We are trying to get one of the episodes recorded to show the vet next time we take him in. The seizures, if that is what they are, are relatively minor compared to what I have read about. He seems very out of it while it is happening but snaps back to normal very quickly, with the exception of following my partner around obsessively (more than usual). One friend suggested it might be caused by diet (preservatives and trace metals). Yesterday, we switched him to all natural dry and wet food so we will see if that helps – although preservatives and metals can build up in the body over time so it may take a while. Thanks again for all the posts. He has has a few episodes over the past few days but they have been relatively minor.
